• Seagate 3TB hard drive loses format information

  - by Victor Bugarin

  I have a Windows 7x64 Ultimate, 6 GB memory, 1 TB HD. 3TB Barracuda XT HDD. The HDD is installed on a StarTech 4 bays external enclosure I had troubles so I converted to a GPT, created 1 partition and formatted as NTFS. The hard drive I can write and read to and from the hard drive but it will become unreadable at some point while I am copying files or after I have copied files to it. I have copied large Bluray movies and diverse video files, I have also copied 32 GB of pictures, and I have copied about 86 thousand music files in different formats. At some point the partition becomes unreadable and I have to format the partition again (all files lost) and I have to start the whole process again. At some point I have been unable to copy large ISO (Bluray movies) file images. I have partitioned the HDD in 2 partitions P1 - 2TB, P2 - 1TB and I have lost every single file in either partition the same way. I reformat the HDD and it seems fine. I have run seatools to check the hard drive and it reports to be OK. What gives?

• Fedora 19 no longer bootable

  - by Parisa

  I had fedora dual-booted with windows on my laptop for a while but with windows refresh grub was gone and my system directly booted windows. I booted fedora with my systems boot options and with this tutorial: https://fedoraproject.org/wiki/GRUB_2 I reinstalled grub2 but then had my system booted into an empty grub prompt: grub So I found the drive containing vmlinuz and initramfs (completely sure about thair location and versions) and tried to manually boot it but after the boot command it said: no suitable video mode found booting in blind mode and nothing happened. Such a tragedy... I have already tried to use live disks rescue system. Funny but troubleshooting options don't apear on my laptop while they do on my desktop pc. I cant even go to boot prompt on my lenovo idepad z400 laptop. I also tried EasyBCD so maybe I could boot it with windows but it comes up with this error: missing AutoNeoGrub().mbr Now I have removed the grub prompt (don't know why) and its really hard for me to reinstall my dearly customized fedora. If anyone knows a way to help boot it again or reinstall it keeping my files and installations I really need it. Thanks PS:I have already tried Boot-repair Disk but it asks me to enable the repo containing grub-efi on my fedora to reinstall the grub2 and fix the boot for me (how could i?).

• Windows 8 install from USB freezes

  - by Rafael Almeida

  I'm trying to install Windows 8 from an 8GB Kingston Data Traveler. I'm currently using the Windows 7 USB DVD Download Tool to put the iso into the flash drive. It copies the files, but in the end it says it 'had a problem with bootsect' and could not make the flash drive bootable. This seems to be because my current system is Windows 7 32bits, and the bootsect.exe in the ISO is a 64-bit executable. Then I downloaded the 32-bit bootsect.exe and made the drive bootable by running: bootsect /nt60 E: /mbr Then I restarted and managed to boot via the flash drive, but now everything is very slow. It takes about two minutes for the initial black screen with the Windows logo and the spinner go away, then it goes to a purple-ish blank screen that stays on for about five more minutes and then it finally shows a dialog asking for the installation, date/time and keyboard languages. I input then, click "Install Now" and it takes about three more minutes with a "Setup is starting" screen. After that, the PC apparently reboots, the CPU fan speeds up considerably, and there's no video and nothing more happens even after more than ten minutes. What is happening? I already tried using another USB port and even installing from a Samsung G3 Station 2TB external hard disk, but the same thing happens. The file transfer speed to the Kingston drive was about only 3 megabytes per second.

• Scaling a LAMP website hosted on EC2

  - by Gublooo

  Hello, I'm very new to all this - I've recently managed to launch my website on EC2. As next step, I want to learn how to scale the website. I have a general idea but wanted some input from the experts about how to go about it. My website is based on LAMP but also has Red5 server which allows users to record messages and also used for playing them back. Currently this is the architecture I'm planning to setup for initial scaling. Deploy four small EC2 instances for the following purposes: Instance-1: On this instance I will run the MySql database Instance-2: On this instance I will run the red5 server Instance-3 & Instance-4 These 2 instances will be used to deploy the website and will have Apache running on them. They will communicate with the mysql server on Instance-1 and red5 server on Instance-2 using the internal IP address. As an when required, I will launch another instance of the same EBS - I will have EBS of say 50 GIG where all the mysql data will be stored. Also red5 will use this EBS to store the video messages Load-Balancer - Use the load balancer provided by Amazon to load balance Instance-3 and Instance-4 This is what I have in mind. I could be way off so please bear with me. Also I have not taken into account the case of scaling MySql server as I currently have no idea about how that will be done and whether or not it is necessary initially. I am aware that Amazon provides auto scaling and mysql scaling as well but I dont want to get into that right now. Your feedback is appreciated Thanks

• Is 1GB + 1GB RAM better than 2GB +0.5GB?

  - by pibboater

  My laptop has two slots for RAM, and currently has two 512 MB chips, for 1 GB. Windows XP is running terribly slow on it, so I want to upgrade the RAM. I could buy two 1 GB chips to replace both of the current 512 MB chips, to give me 2 GB of RAM. Or, the price is the same to buy one 2 GB chip, to replace just one of the 512 MB chips, and give me 2.5 GB total. The RAM it takes is PC2-4200 533MHz DDR2. What do you think would be better: buying two 1 GB chips so it can take advantage of dual-channel operation, or buying one 2 GB chip to end up with more total RAM but not dual-channel operation? Like I said, price is the same, so performance is the only consideration. I'm not doing anything especially intensive like video or photo editing -- just having multiple Office programs open, playing music, browsers, etc., but currently even opening the first application takes forever. If it matters, the laptop is a Toshiba Qosmio G25-AV513 running Windows XP Media Center SP3. Thanks! Kevin

• Games on windows 8 in bootcamp lag even on lowest graphics

  - by Jackson Gariety

  I've been playing Crysis 2 and Skyrim on my Retina MacBookPro (10,1) for months now. The two games used to run super smoothly even on nearly maxed out settings. This laptop has an Nvidia GeForce GT 650M graphics card inside, it runs great. But I recently replaced my Windows 8 consumer preview with the retail copy, and since then, 3D games lag in this odd way, no matter what the graphics settings. Every second Skyrim and Crysis alternates between running smoothly and lagging. It's a cyclical lag that comes and goes like clockwork. I can turn the graphics down to 800x600 with no antialiasing and low texture quality, and it runs much smoother on the "up" motion of the cycle, but every second it moves back into this lag spike. I've tried installing beta graphics drivers, re installing the operating system, re installing the bootcamp support software, and freeing up space (I have about 20 GB free). I can't figure out what suddenly caused this other than some obscure difference between the consumer preview and the retail version. What can I try? Is my video card failing? Are there some other drivers I can install? This isn't normal lag from maxing out the card, it

• How can I take browser screenshots at a higher resolution than my browser supports?

  - by user53575

  I need to take a screenshot of a website as it would appear on a very high resolution monitor... say 16000x12800 pixels. My laptop's screen has a native resolution of 1280x800. Basically, I need to simulate having a monitor resolution much higher than my monitor and video card actually supports. I want the screenshot of the site to look pretty much how it does when you hit CTRL MINUS (zoom out) in Firefox repeatedly, but without any loss of pixels due to scaling. How can I do this? Is there some way to use virtual machine software to simulate a super-high-res display? If not, is there some way to open a browser window bigger than the screen, and then capture its contents as a PNG somehow? Anything else that might work? Here was an answer: http://superuser.com/questions/120266/how-can-i-take-browser-screenshots-at-a-higher-resolution-than-my-browser-support But it doesn't work. Firefox remains in the resolution of the physical screen. The window blinks and shrinks back to normal resolution. Please Help!!

• Power surge PC damage: How can I test all components of my PC without access to a second computer?

  - by Doug T.

  Ever since we had some crazy power surges last week my 64 bit Windows 7 PC has been acting strange. My USB network adapter disconnects from the wireless and can't detect the signal. I have to disable/reenable the adapter to detect it again. Also my wife has reported that the PC has rebooted a few times while I'm not sitting at it. Today I finally caught the reboot while I was using the PC. I got this blue screen of death. Stop Code 0x00000109: "Modification of system code or a critical data structure was detected." I followed the advice at the linked article and ran a memory test. I used memtest86 and its already found around 300,000 errors out of 8 gigs of ram. Now I'm worried -- what are the odds this is isolated to just my memory and not just a system wide problem? Isn't there a good chance that many other components are fried? More importantly, how can I test those other components? Are there tools similar to memtest I can use to test my motherboard/video card/power supply? If these are vender specific, is it typical for vendors to provide testing tools?

• Using sound forge 6.0 what will be the need to upgrade to latest version

  - by Jayapal Chandran

  I had been using sound forge 6.0 not recently but long back. I edit mp3 files for my purpose and some more filters like flange, pan, fade in out, recording, line in recording, extracting sound from video files (mpg, avi(divx), etc...), increasing the default volume, editing treble and bass effects, and etc... I am not going to use it professionally. I use it just like that. Now when i checked i could see Sound Forge Audio Studio 10 is the latest version for my purpose. Others are too high i think. Besides, i had been using Gold Wave version 4 very extensively just to edit sound files mostly mp3. and here is the reason for me to change to sound forge. It is when we edit mp3 files it deflashes(making it raw i think) before editing. after editing if i save it asks for the format to save and i will choose mp3. At this point it again applies the compression process which makes the sound file lossy. When i did the same with sound forge it did not deflash. It just edited the file as mp3. May be i dont know whether gold wave has the same option. So, please suggest. oh i had asked a question already like this... here it is goldwave vs sound forge in editing mp3 files

• Graphics artifacts/distortion with Win7 and nVidia

  - by Gepard

  Problem I encounter is rather hard to describe, so I provide a screenshot: http://dl.dropbox.com/u/1732760/video-distortion.png As you can see there are some horizontal stripes in random colors. These stripes appear sometimes in all windowed apps, games and on the desktop too. They tend to stay in place until I refresh window (or force it to to redraw by for example minimizing and maximizing again). They also tend to appear in the same place and shape multiple times, even if they disappear, it's very likely they will be again in the same place after a while. These artifacts do not blink or change if computer is idling. If I don't touch anything, do not use mouse, they will stay in place forever (unless some app redraws its window on its own). I first encountered this problem some weeks ago. Back then I thought it might be cooling problem, so I took out the graphics card, removed dust from the radiator and fan and put it into PC back. I also ran some stress test using Furmark (peak tempearature was ~65C) to see if the problem becomes more intense if the card gets hotter, but suprisingly no artifacts whatsoever appear during the stress test. Graphic card is Galaxy GeForce 7300 GT with DDR3 memory, was never overclocked. Drivers are the latest, from Nvidia site. OS is Windows 7 64-bit, updated. AMD64 3000+, 2GB RAM. I'm running a dual monitor setup with 2 19'' Samsung LCDs and problem is on both, so I assume it's not a monitor or cable issue.

• Computer will not boot - disk read error - cannot boot from HD or DVD

  - by Grant Palin

  This is a 3 year-old system: HP a1640n. There have been no issues with it in the past. I added a video card 2 years ago, and more memory 1 year ago, both without issues. There haven't been any recent hardware changes. I did install Win7 in Oct., but there were no issues with that either. I used the computer fine two nights ago, and turned it off. Yesterday, I tried to turn it on, and got the error: "A Disk Read Error Occurred. Press CTRL ALT DEL to restart" So I restart, see the initial start screen (HP) and enter the BIOS. The hard drive and dvd drive appear to be listed, but the names are gibberish text. I tried putting a Windows disk in the dvd drive, and continued with the boot, but the disk did not get recognized. Even though the BIOS was set to check for optical media before the hard drive. Back to the error screen. If the computer would boot from a cd or dvd, I would just figure the hard drive needed replacing. But both being problematic worries me. Is this a matter of replacing both the hard drive and dvd drive, or might it be an indication of a bigger problem? Thanks for any advice.

• Windows 7, Black screen with cursor, impossible to logon

  - by PJC

  First - I have gone through as many possible solutions I've found here and elsewhere. [Edit - to describe the issue in more detail, the PC appears to boot correctly, but instead of the logon screen, I have been getting a black screen WITH the pointer cursor, and it responds correctly to the mouse. Pressing CTL-ALT-DEL brings up the logon screen's background, but with no logon area nor any other content. This screen was at the full resolution before I uninstalled the graphics driver in safe-mode.] I also just ran a full up-to-date AVG scan from boot media. [Edit - the AVG scan, which was updated to today's virus signatures, found no issues at all.] So - steps I've tried: Safe Boot, Restore from before the issue - done, no help. Uninstall the graphics driver - done, now i have a 1024x768 fallback screen, still no way in. sfc /scannow - only doable from Safe boot obviously, but no change. [Edit - booting from restore media, performing a startup repair and...]Restore further back - restored to 2 days ago, and I'd had many reboots since then with no problem. Enable autologin to try to get beyond the login screen - done, doesn't work. It seems the best advice is complete reinstall, but I really don't want to do that because it'll take 3-4 days to add all the apps I use. Some key points to note - in both states - before and after removing the video driver, I always had a mouse cursor on the screen. CTL-ALT-DEL flashes up the login background, but no login info. I can (and often do) reinstall from scratch, but was at a fairly stable state before this, and would prefer not to. -Paul

• My Samsung R480 laptop freezes for short and inconsistent periods of time.

  - by anonymous

  I have a Samsung R480 laptop running Windows 7. It's great, I love it to death, but every so often it'll start having, for lack of a better term, "hiccups". It would freeze completely, emit a loud BZZZZZZT from the speakers (think when a video freezes and the sound gets stuck), then return to working order all in a span of 0.5~2 seconds. It has happened while I was playing Mass Effect, while I was watching both HD and non-HD videos, and while I was surfing the internet (which I've noticed while watching YouTube videos and playing Entanglement, but also noticed while using Facebook, minus the buzzing sound). My Initial hypothesis was that my GPU or CPU were overheating as it would shut down while playing Mass Effect, but when I turned off my WiFi card hardware using [fn + F9], the problem was resolved. As I currently see it, it could be a problem with my CPU, my WiFi card, or my sound card. It could also be a software related issue, possibly an ill-functioning process. It could be chrome related. A memory leak from chrome maybe? Does anyone know how to resolve this?

• Data loss by randomly unplugging the computer during runtime

  - by Kan

  I'm from Austria and we and the Germans have some sort of bad science-show which runs every day. What I call it would rougly translate to "half-knowledge" if you want so. By the way: It is called "Galileo". So they thought they'd make a computer myth busters video right now, and I couldn't believe what I saw and heard... The strangest thing to me was that they asked: "Does unplugging the computer damage your data?" Then they started up some machine with Vista on it, started copying some files and randomly unplugged the PC cable, the whole thing around 50 times. After their computer continued to start up normally, they just said "nothing can happen, your data or computer can't be damaged". They of course excluded unsaved data in running programs like text editors from this. I asked myself: What the hell are their "computer experts" saying? You can't tell by unplugging the cable 50 times if that can damage your computer. Can unplugging the cable during runtime cause data loss (as said by the moderator of the show)? (I destroyed my windows registry once during a reset)

• Upgrade or replace?

  - by Felix

  My current PC is about four years old, although I have made upgrades to it throughout its existence. The current specs are: (old) Intel Pentium D 2.80Ghz (32K L1 / 2M L2), Gigabyte 945GCMX-S2 motherboard (old) 2.5GB DDR2 (slot0: 512MB @ 533Mhz; slot1: 2GB @ 667Mhz) (new) HIS Radeon HD 4670 - I think this is limited by the motherboard not supporting PCIe 2.0 (?) (old) WD Caviar 160GB - pretty slow (new) WD Caviar Black 640GB (if any more specs are relevant, let me know and I'll add them) Now, on to my question. I've been having performance issues lately, both in video games and in intensive applications. A couple of examples: Android application development (running Eclipse and the Android emulator) is painfully slow (on Linux). I only realized this when, at my new job as an Android dev, both tools are MUCH quicker. (I'm not sure what CPU I have there) The guys at my new job got me NFS Hot Pursuit, in which I barely get like 5-10FPS, even with graphics options turned all the way down My guess is that the bottleneck in my system is my CPU, so I'm thinking of upgrading to a Quad Core i5 + new motherboard + 4GB DDR3 (or more, 'cause I know you'll all jump and say 8GB minimum). Now: Is that a good idea? Is my CPU really a bottleneck, or is the whole system too old and I should replace it? I run Windows 7 on the old, 160GB HDD (which is on IDE, by the way). Could this slow down games as well? Should I get a new drive for Windows if I want to play new games? I know nothing about power supplies. Could that be a problem / will it be a problem if I upgrade to an i5? How come DiRT2 works on full graphics settings (pretty amazing graphics by the way) and NFS Hot Pursuit pulls only 5-10FPS?

• Hard Drive problem: is it the SATA controller or the HDD itself?

  - by Drooling_Sheep

  I have a Samsung 1.5TB hard drive hooked up to an ECS H55H-I mini-ITX motherboard. I have XBMC 10 (modified Ubuntu 10.04) installed for use as an HTPC. The hard drive encounters occasional errors during normal use which cause it to be remounted read-only. I have updated the BIOS on the motherboard, changed the SATA cable and moved it to different ports on the motherboard, installed and re-installed the OS (including different versions of XBMC and generic ubuntu), all to no avail. I recently ran tests both with badblocks -sv and smartctl -t long. Both reported no errors. This makes me think the motherboard or SATA controller is probably the issue. Does anyone know of any further tests I can do to help narrow this down? The processor is a Core i3. I forget the model number but it's one of the 32nm ones with on-package graphics. There's no discrete video card or optical drive. The power supply is a 150W Rosewill (pretty sure) that came with the case.

• Did Adobe Photoshop just killed my Graphics Card for good?

  - by user6004

  I was working with Adobe Photoshop, just some regular work, when I came to edit a PSD file and change the text of some layer, when all of a sudden the PC froze. No mouse, screen is frozen, keyboard strokes aren't getting me anything, no Task Manager, nada. So I rebooted my PC, and then something quite terrifying appeared before my eyes. It was not the Checkdisk utility that was launched, that made me terrified (by the way, that reboot damaged the partition table of an external HDD that was connected at the time to my PC, but that's another story). It was the screen itself. Please have a look. So after Checkdisk finished and Windows loaded, I noticed that the resolution was not right. Instead of 1440x900 which I had set, it was 1280x1024. When I went to change it back, I had no option to change back to my old resolution, and has only 3 other general resolution properties, as if my Video Card (GeForce 8800 GTS btw) was not recognized. And what do you know, in the Device Manager it appeared with an exclamation mark. Inside the hardware, it said this: Windows has stopped this device because it has reported problems. (Code 43) Uninstalling the drivers, downloading the newest drivers from NVIDIA and installing them did not work. It always comes back to this. So, do you have any advice before I go out and buy a new graphics card? I thought this was the only option left, but maybe the experts at Super User can help me out. By the way, the dotted screen appears after every reboot, and I see the dots when the ASUS Motherboard screen shows up at boot. Thanks in advance.

• Linux can dual display but windows can't?

  - by Mr_CryptoPrime

  I have two monitors, one that is hdmi-to-dvi and the other vga-to-dvi. I have an AMD HD Radeon 6900 series graphics card installed. I got Ubuntu to display dual monitors, but then I restarted for an update and then Ubuntu wouldn't even boot in recovery mode, it just kept cycling forever...displaying something about "timeout: killing [filepath] [hexadecimal]. So I tried booting into windows (7-professional) and it crashed and displayed this after rebooting: IRQL_NOT_LESS_OR_EQUAL, PAGE_FAULT-IN-NONPAGED-AREA. I went into Bios and reverted to the system defaults and ran system restore and it booted ok, but the dvi-to-dvi monitor would not display. I made sure my drivers were updated and catalyst was updated. Also through research discovered only one is for vga and the other is digital only, so I put the vga-to-dvi in the vga slot and so on. Neither windows or catalyst will detect the dvi-to-dvi montior. Any suggestions? Thanks. EDIT: Found out that booting into Ubuntu with only one monitor (using either monitor with either cable) worked perfectly fine. I could then add another monitor and it displays ok. However, it will, out of the blue, suddenly distort the display. At first I thought the computer crashed, but it is something with the video output from the GPU to the monitor because I pushed the power button and it would refresh every 5secs or so and I could see the "Ubuntu will power down in X seconds", even though it was horribly distorted. Any ideas what's causing this?

• Out of memory errors but not actually out of memory...

  - by commradepolski

  So, myself and my fellow support techs have been fighting with this issue and we still dont know what the problem is. Lets start off with the system specs: Windows XP 32 bit Corporate (SP2 and SP3) Intel D975XBX2 Mobo 4gb of ram Intel Core 2 Quad Q6600 ATI Radeon HD 3600 - 512mb After a few hours of working on the machine, the end user will begin to see the following symptoms: Out of memory messages Title bars and menus dont draw in properly Problems accessing network resources Problems opening up documents such as MSWord and MSPowerpoint and text files Problems opening up explorer windows General instability We have looked at task manager while this issue was occurring, and all indicators, like PF usage, threads, handles, etc. are normal. We have been having trouble pinpointing the root cause of this issue. It is also not situated with one user, it affects 8-10. So far we have tried: Resetting CMOS (Waiting to see results) Replacing video card (didnt help) Windows updates (didnt help) Updating network drivers (didnt help) Switching user from 1gbps to 100mbps network connection (awaiting results) Swapping the affected user's hardware (waiting for results) Increasing desktop heap size (helped for a bit but then the issue became more frequent) Applying the /3 switch to XP (didnt help) Increasing and decreasing and setting PF to system managed state (didnt help) We did have a power outage at the office a couple weeks ago, and all these issues became more frequent. Prior to the power outage it may take a week or so for the users to experience the issues but since the power outage it takes 3-4 hours or less. We havent had reports of the above issues causing BSODs, although that would be easier to diagnose :). Any help is greatly appreciated.

• PC doesn't POST with a certain model of PSU

  - by Core Xii

  I have this PC with an Asus P5N32-E SLI motherboard and an Intel Q6600 CPU. I got a new RX-5300 PSU, but it didn't work. The motherboard power LED is on fine When I switch power on, the PC powers up briefly (0.5-1 sec) then shuts down From there on out when I switch power on, it stays on, all fans and components seem to be receiving power, but the motherboard won't POST. No video output, no PC speaker beeps, nothing If I turn the hard switch on the PSU off and then back on again, go to step 2; The PC turns on and then off immediately again, and on subsequent power-ups it stays on but won't POST I disconnected every component but the motherboard, CPU and PSU. Still nothing. I tried three other models of PSU on this PC, both of higher (600) and lower (<300) wattage than the 530 on the RX-5300 and they all work fine. At this point I was convinced the PSU was faulty so I returned it. When the replacement arrived, it behaved exactly the same. So two different units of RX-5300 both with the same symptoms, neither working with this motherboard + CPU. Yet, three other models of PSU work perfectly fine. The PC store couldn't reproduce my problem with the returned PSU. I tried resetting the CMOS with the jumper. I tried with both the 4 and 4+4 (with and without the extra +4 connected) CPU connectors (curiously the RX-5300 comes equipped with both). Could it be a statistical probability that I get two units of the same model of PSU that are faulty in the exact same manner? Could the RX-5300 model itself be somehow incompatible with this motherboard? I was under the impression that PSUs were pretty much universal so long as you have the wattage. Could the motherboard be broken in some such a way as to work with certain PSUs but not others? What's going on here?

• 3-4 old computers = general purpose cluster?

  - by TheLQ

  I have 3 old computers lying around right now running a P2 at 800 MHz(?), Intel Mobile 1.6 GHz, AMD Athlon XP 2000+ at 1.66 GHz, and (might not use this) P4 at 2.7 GHz, all with 512 MB Ram, and am considering clustering them together for fun/knowledge. They would be running an undecided version of linux, preferably ubuntu based. The issue is what I want to use it for: general computing and occasional video encoding. By general computing I mean day to day tasks. However I'm not sure if every program started by a single X session is going to exist on the same machine, defeating the purpose of such a system. Will programs be split up or exist on one machine? Second, assuming this is running 100baseT ethernet (not sure if the PCI slot itself could handle Gigabit), would the speed of having a program exist over the network be an issue? It seems that the constant asking of various things in RAM would be quite slow. And before you say "buy another computer!", that's not the point of this question. I'm asking would it be usable, not necessarily practical. And yes I know, this is going to be extreamly power consuming.

• If I run two monitors from two different graphic cards, can I still have Twinview?

  - by rumtscho

  I am planning to get a second 2560x1440 monitor for home. The trouble is, I only have 1xDVI, 1xVGA on my graphics card (a 250 GT). I don't want to buy a new graphics card until the prices for the 500 series have stabilized, so probably not before summer (or will it happen earlier? I don't remember how it was for other series, and I couldn't find long-term price history for video cards). The solution I had in mind is to get the 7600 GS from my old PC, which also has 1xDVI, 1xVGA, and run each monitor on a separate card. I have never done that, and I was wondering 1. If I will be able to run the monitors in Twinview then, or will I be stuck with separate X sessions, and 2. Whether there are some other disadvantages as compared to a single-head graphics card. (I am using the proprietary driver because I need compiz). As an aside, how do I find out whether the DVI port on the old graphics card is dual link?

• Is there any way to shut up my ATI HD 5770?

  - by slpsys

  So to preface, I basically built Jeff's machine; I already had some of the components, including (scarily enough) the exact same case1. I've been buying bits and pieces over the past few months, which coincided perfectly with his recent post about three monitors, though not being a gamer outright, I opted for the second-from-the-bottom option. After finally plopping all the pieces lovingly into the case this evening, I turn it on...and it sounds like four professional grade hair-driers. Some quick regression analysis determined that with the video card out, the running machine sounded no louder than our house's vents. Basically, my last desktop build included a $45-at-the-time graphics card, and it's been Macbook Pros and workstations since then, so I have zero idea whether I'll just be able to tune the fan speed later on. Will I be able to get this thing to quiet down every time I'm not playing Modern Warfare 2 at maximum framerate, or should I just send this thing back now, and get the quietest card in my pricerange? 1 One thing of note is that I do not have noise-absorbing foam in the case, as is pictured in the article. I'm only mentioning that because I suspect it could drop the overall output a few decibels, but obviously not that many.

• Installed Memory (RAM): 8GB (4GB Useable)

  - by Mike Bannister

  I have 4X 2GB RAM sticks installed, Windows 7 Ultimate x64 shows "Installed Memory (RAM): 8GB (4GB Useable)" in the system information. The motherboard says it supports up to 16GB of memory. I had Windows XP x64 and I'm pretty sure it was able to use all 8Gigs of memory. I've just formatted and am not burning through 4GB for sure. *The BIOS only show 4096MB while booting. I was only able to find one option relating to memory mapping and it took it from 4Gigs to 3 and change. CPU-Z shows all 4 sticks as 2048MB I went in to msconfig and checked the limits, they are not set. I tried resetting the CPU and RAM sticks 3 times, the CPU has no pins to be bent (flat contacts, I5) I rearranged all the RAM. I have separate video memory from the system memory. I have a 64 bit OS (I am 100% certain) Hardware: Memory: Four Corsair XMS3 TW3X4G1333C9AG Motherboard: Asus P7P55D Pro CPU: Intel Core i5-760 BX80605I5760 Graphics: Two ZOTAC ZT-50401-10L GeForce GTX 550 Ti If anyone has new ideas or knows the exact setting in the bios, it would be greatly appreciated.

• Windows 7 host with Ubuntu Guest and a performance hit, memory locks?

  - by Cyrylski

  I have a brand new Lenovo T510 with Core i5 and 4GB of RAM with Windows 7 on it. I Installed Ubuntu 10.10 in a Virtualbox. For some reason system gets really slow on this setup which makes me really angry. There's a video card shared with full 3D support enabled and 1GB of RAM allocated for the Ubuntu machine. It may sound stupid, but WHY is the whole memory consumed in an instant when I run Virtualbox? I struggled for like 10 minutes restraining myself from a brutal reset, and now everything runs smooth but memory "in use" in Resource Monitor is 3GB flat with only Chrome running. I'm new to Windows 7, but I'm really disappointed with performance at this point... I used to work in a different environment with much slower hardware and there was no such problem (WinXP over Ubuntu, 1GB out of 2GB allocated for WinXP guest on intel GMA). This is, until I clogged RAM totally there. But I was capable of running Chrome, Firefox and Apache server on a 1GB RAM in Ubuntu there and Photoshop CS4 on Windows XP and it worked. In this case I can't go beyond setting up Ubuntu properly. I bet I'm doing something wrong.
