  - by Puneet Dudeja

  My laptop windows 7 power settings are not working since last week, i have tried using "Dim display after 5 hours" and "Dim Never" also, but my screen goes black after 1 minute. Any resolutions ?

• Cutting and pasting in MS Word: hourglass pops and it takes longer than expected

  - by Rax Olgud

  I work with MS Word 2007. Today I created a new document, and for some reason cutting and pasting text (using Ctrl-X and Ctrl-V) takes longer than expected. To clarify, here's the process: I select a single word in the document I click Ctrl-X The hourglass shows up for 1-2 seconds The word is cut The same happens for pasting (i.e. 1-2 seconds of hourglass). This document is ~5 pages long, with nothing fancy. I have plenty of available RAM and my CPU usage is around 1-2%, there's not peak during the cut/paste. Any thoughts on what can cause this and what I can do against it?

• Script errors when run by launchd at startup, but not when run in Terminal

  - by Mechcozmo

  I'm attempting to create a RAM disk that loads the previous contents when the system starts up, and every six hours writes the contents to a disk image. Currently, when you run the script from the terminal ("sudo bash LogToRAM.sh") everything works fine. But when run from launchd during startup, it doesn't work. Here's the lines from the log; the first line just gives some idea as to where in the boot process we are: SecurityAgent[202] Showing Login Window com.mechcozmo.LogToRAM[51] + /Developer/usr/bin/SetFile -a V /Volumes/LogfileRAMdisk com.mechcozmo.LogToRAM[51] ERROR: File Not Found. (-43) on file: /Volumes/LogfileRAMdisk com.mechcozmo.LogToRAM[51] + /usr/sbin/asr -source '/Library/Application Support/LogToRAM/RAMdisk_store.dmg' -target /Volumes/LogfileRAMdisk/ -noverify Here is the script and plist file in question. Note that 'set -vx' is up at the top of the script; it give a lot of information about what is happening in the script. My current theory is that the /Volumes directory does not exist at this stage of the boot process, but that seems unlikely to be honest.

• Windows 7 Taskbar disappears overnight

  - by eidylon

  Hello all, I've got this problem that started happening recently. Overnight, something is happening that makes my taskbar disappear on my laptop. The Start orb is still there, and if I click it, it pops up the start menu, but the whole rest of the taskbar, including the background behind the start orb, is just completely vanished: tray icons, running programs, clock, everything. I tried killing explorer.exe and restarting it, but it doesn't restart. And after killing it, Task Manager won't let me start ANY programs. It gives no errors, just ... doesn't run them. Anyone else see this or know what it might be? I'm running Windows 7 RC on an IBM ThinkPad R51 with 2GB ram.

• Should server spare parts be stored in climate controlled storage?

  - by Shane Wealti

  What is a best practice for storing server spares (hard drives, RAM, power supplies, etc) with respect to how/where they are stored? Some options are storing them in climate controlled storage or just a standard warehouse-type stockroom? My understanding is that all other things being equal climate-controlled storage is preferred. What are the risks of storing that type of thing in a non-climate-controlled, somewhat dusty shelving area? Conversely are there risks to storing spares in a climate controlled area? If there are space limitations in climate controlled storage are there some parts, such as hard drives, which should be in climate controlled, while other parts such as power supplies will probably be ok in non climate controlled storage?

• Need advice on PC components for high-end games but in limited budget

  - by Md Atif

  I need advise, I want to buy PC components which will be good for gaming as well as be under my budget. First thing I chose is Graphics card : ATI HD 7850 2GB DDR5 then matching things up with this selected following: Processor: AMD 3.5 GHz AM3 FX 8320 8 Core Piledriver Mobo: MSI 990FXA-GD65 RAM : 8GB DDR3 (4x2) Is this setup looks compatible? If making any of above component inferior will have negligible affect on performance/gaming(like buying 970 chip mobo instead of 990) then please let me know so I can save some money :) ? Any other advice?

• What would be better in my case - apache, nginx or lighttpd ?

  - by The Devil

  Hey everybody, I'm writing a php site that's expected to get about 200-300 concurrent users browsing it. When initializing the application will load about 30 php classes, some 10 maybe 15 images and a couple of css files. So my question is what else can I do (except optimizing my code and using apc/eaccelerator for php) to get as close as possible to those numbers of concurrent users ? Currently we haven't chosen a server for the site to be hosted on but most probably it'll be a VPS Dual core + 2 or maybe 4gb ram. Is it possible for such a server to handle that load ? Also how could I test it myself and be sure that it'll be able to handle it ? Thanks in advance, Me

• Rules to choose hardware for OLTP systems (sql server)

  - by Roman Pokrovskij

  Ok. We know database size, number of concurrent users, number of transactions per minute; should choose number of processors, RAID, RAM, mirroring and clustering. There are no exact rule.. but may be there are no rules at all? In my practice in every case I have "legacy" system, and after some inspections and interview I can form an opinion how hardware and design can be improved. But every time when I meet "absolutely" new system (I guess there are no new systems, but sometimes are such tasks) I can't say anything trustful. So I'm interesting how people deal with such tasks? They map task on theirs experience or have some base formulas?

• What causes Windows Boot to stall?

  - by Nick Berardi

  For about 6 months now I have been having this weird problem where Windows 7 fails to fully boot correctly. What happens is this. Starting Windows shows up on the screen. Then 3 out of 4 times nothing else happens, no Windows Flag animation, just nothing occurs. After 3 or 4 restarts repeating steps 1-2 above, the Windows Flag animation finally shows up and everything works as expected. My question is what is causing this problem in steps 1 and 2? Because I have tried the following with no luck: Error checking and correcting of any disk errors Updating drivers Doing a clean install of Windows 7 My setup is as follows: Windows 7 64-bit Ultimate 8 GB RAM 128 GB Crucial SSD (firmware 0005) Dell Latitude E6410 Intel Wireless and Graphics Other than what I have tried above I am totally out of ideas and looking for some new ones to try.

• Dell Studio XPS 16 Runs Hot

  - by dtbarne

  Specs: 1920x1080 i7 1.6 GHz quad core 6GB RAM 1GB ATI Radeon HD 6570M/5700 Series 500GB 7200rpm Hard Drive Love this laptop for many reasons, but it constantly runs hot (CPU is low 70s with basic tasks and often 80+ is not uncommon) and I'm finding it too much to deal with. The laptop feels very hot (almost too hot for a lap) and often gets so hot that the OS slows down or freezes altogether. I've tried cleaning it out and even replacing the thermal paste. I often use an external cooler, but it only helps 3-5 degrees and it's a pain to have to use. I've come to the conclusion that it just runs hot. I have two questions: What is to blame? The i7 processor, the gfx card, or is it just that this laptop has poor cooling? Does the Dell XPS 15 run cooler? I'm looking at replacing my current laptop, but I don't want to run into the same problem.

• Debian Linux server hangs after a week or so

  - by Alex Flo

  I have 2 Debian Linux 6.0.4 servers that have a strange behaviour: after 5-7-10 days they hang. By this I mean the servers need to be restarted and before that ping won't answer. I've been struggling with this problem for a couple of months now and here's some thoughts/what I tried without being able to solve the problem. I changed the RAM on a server. Being 2 different servers I doubt that it could be something related to hardware as a 3rd identical server won't have this problem. I logged the server load and when it crashes the load is fine (quite low) I cannot find anything in the server logs, logs are fine till the server freezes. I don't have access to console unfortunately. While I have years of admin experience I have never encountered such an issue and right now I have no idea where else to investigate. If you have an idea of what I could try in order to fix the problem please share it with me:-)

• MySQL keeps crashing OS server.. Please help adjust my.ini!

  - by TruMan1

  I have MySQL 5.0 installed on a Windows 2008 machine (3GB RAM). My server crashes on a regular basis (almost once a day) with this error: Changed limits: max_open_files: 2048 max_connections: 800 table_cache: 619 I did not use the heavy InnoDB .ini file, although I am rethinking that I should have? I am worried that big configuration changes will make my current sites stop working. What should I do?

• ASUS K55VM Laptop unexpectedly shuts down

  - by Abhishek Sha

  I've read quite a few questions on SuperUser of people having laptop shutdown problems but mine is different. My laptop specs: Intel Core i7 3610QM (IvyBridge) NVIDIA GT630M 2GB and Intel GMA4000 8GB RAM Windows 7 64 Bit My laptop occasionally shuts down when playing FarCry 3. It's around 5 months old. I've played games like Crysis and it never shuts down unexpectedly. Since I experienced this shut down recently, I decided for GPU-Z to log the temperatures. The final log value at the time of shutdown were thus: GPU Core Clock [MHz] - 797.3 GPU Memory Clock [MHz] - 896.8 GPU Temperature [°C] - 89.0 GPU Load [%] - 99 Memory Controller Load [%] - 36 Video Engine Load [%] - 0 Memory Usage (Dedicated) [MB] - 535 Memory Usage (Dynamic) [MB] - 53 VDDC [V] - 1.0620 My drivers are up-to-date and I didn't encounter any BSODs at the time of shut down. It simply turns off.

• Using MongoDB + Redis + Apache on the same server in production?

  - by Dayson

  I intend to launch my web app using a 8 GB VPS. It uses MongoDB + Redis for storage/caching and Apache + PHP-FPM for serving requests. Could there be any issues with running Mongo + Redis + Apache on the same server? Would it make more sense to setup 2 x 4 GB VPS servers and keep Mongo on one and Redis + Apache on another? Should I just start with one server and worry about scaling horizontally later by delegating the existing server to Mongo in the future (due to its large RAM) and moving the web servers on to multiple smaller VPS'?

• PHP Script causing high CPU

  - by user20996

  I have a website which is causing me a major headache. There is one PHP script which is using far to much CPU, this only seem to happen when bots hit the site, I dont want to block all the bots because we need them. I have the the process manager output: Pid Owner Priority CPU % Memory % Command 16943 (Trace) (Kill) specialone 0 99.4 1.0 /usr/bin/php /var/www/specialone/page.php I ran strace -p 16943 on the process but it comes up with nothing. We have 2GB of RAM and the php memory_limit is set to 128M which should be enough. The trouble I have is the PHP code is a Framework and the culprit page.php pulls in a lot of other PHP files so I cant debug the PHP. Is there any way of finding out what the script is doing when its using so much CPU which will help me solve it?

• Do I really need Microsoft Updates?

  - by Tony Wong

  When I install a fresh copy of Windows XP Home (I bought it from the store.. not a copy), my PC rocks like lightening speed. But when I start installing all the updates, patches & less .NET 4.0 client (as the .NET 4.0 Client seems to bring machine to slow crawl). The PC starts to slow down.. like there are more resources to watch or something is happening in the background. So could I not get away with an awesome virus protector and an awesome firewall set-up and avoid all the patches? The machine I have is a quad 4, 4 GB RAM and 2.3 GHz process. Tons of room and the machine can run several applications at one time.. but when the updates happen.. it's s-l-o-w!

• windows 7 frequently crashes when running 64 bit debian on virtualbox

  - by erin c

  I've been having some hard times with Virtualbox. I use it to run 64-bit Debian guest on a Windows 7 host to be able to code for linux systems. It generally crashes when I build my code in eclipse cdt, or if I am doing some intensive operations. Should I lower the memory and core usage? Is this some sort of virtualbox problem? I upgraded to virtualbox v4.1.8 and the problem still occurs. My virtual machine instance uses 1736MB out of 4GB of ram, and I use 2 out of 8 processor cores. But still, the whole thing crashes 1 or 2 times every single day.

• SQL 2008 Memory Usage

  - by Danilo Brambilla

  I have a SQL Server 2008 (ver 10.0.1600) running on a Windows Server 2008 R2 Enterprise server with 8 GB of physical ram. If I open Task Manager I can see on 'Physical Memory' section of 'Performance' tab that only 340 MB are Available of 8191 Total, but I can't see any process using such amount of memory. Please note SQL Server is memory limited to 6GB (Maximum Server Memory = 6000). If I open Sysinternals Process Explorer, I can see sqlsrvr.exe process has: Private Bytes: 227.000 K Working Set: 140.000 K Virtual Size: 8.762.000 K What does this means? Is there any way to free up this memory for other process? Why Virtual Size figure as allocated memory? I thought that Virtual Size was 'reserved memory' only.

• Can a 32-bit RHEL4 userland work with a 64-bit kernel?

  - by James

  Is there a way to change an i386 RHEL4 machine to run an amd64 kernel, but ensure that it still builds software into same i386 binaries? On Debian this seems quite straightforward: just install an amd64 kernel (worst case, build one like this guy: http://www.debian-administration.org/users/jonesy/weblog/1) and prefix everything with "linux32". Then everything that considers uname -m will be unchanged, I just need to handle the few cases that consider uname -r. What is the Red Hat equivalent? Is the only way a full 64-bit installation on another disk and then chrooting back to the 32-bit system before anyone builds anything? (Even the best examples of that seem to be Debian-based.) Background: We make a large system that runs on (a variant of) i386 RHEL4. However, some of the larger RHEL build machines now have enough RAM that they might benefit from going 64-bit (for the kernel and maybe some of the bigger build steps). Our build system doesn't support cross-compilation.

• Linux only recognizes 800Mhz from 2Ghz

  - by Leo

  I tried with Suse 11 (KDE), Xubuntu 11.10 and Lubuntu 11.10 and these systems only recognizes 800Mhz from my processor of 2Ghz! The utilities I used are: linuxinfo, sysinfo, "system profiler and benchmark". And all of this only shows 800Mhz My system specs are: AMD Turion 64 Mobile MK36 512 RAM nVidia Geforce Go 6150 (I also tried with nVidia restricted drivers) 120GB Hard drive The weirdest thing is that Windows XP and 7 recognize the 2Ghz of my processor, What can I do? p.s. (It is not just the value of 800Mhz, I also feel my system very slow with linux)

• EEE PC 701/4G Surf Internal Drive: Is it really SSD?

  - by Bart Silverstrim

  I have an old EEE PC with the 4 Gig internal drive. Everything I've read keeps saying it's an SSD drive; running lshw tells me that it's an ATA disk, Silicon Motion SM. The thing seems to be rather slow, though. I know it has a 900 Mhz Celeron processor and only 512 meg of RAM, but it seems like drive access is slow even for those specs. Does anyone know if it really has an SSD drive? I thought that compared to regular hard disks SSD's were blazing fast, and this feels like and acts like it's pulling from something more akin to an internal USB memory stick.

• Windows 7 as VM inside VMWare Fusion - 32 or 64 bit?

  - by webworm

  I have a MacBook Pro with the 2.4 Core 2 Duo and 4 GB RAM. I want to run Windows 7 for ASP.NET development within VMWare Fusion. Since I may be doing some SharePoint 2010 work I was thinking that my install of Windows 7 would need to be the 64 bit version because SharePoint 2010 requires 64 bit Windows. As I am new to Mac OS (I am running v10.6.3) I am not sure if it would support a 64 bit OS in a Virtual Machine. Thoughts?

• Why does the CPU usage reach 100% when laptop is plugged in?

  - by Mayank

  I have an HP Elitebook 8440p with Windows 7 Ultimate, i7 Processor and 8 GB RAM. For the last couple of days, when I plug-in my laptop for charging, the CPU usage shoots up to 100% and remains there for around 15 minutes. No offending process shows up in Task Manager/Process Explorer but the laptop is practically unusable for that time. The CPU usage becomes normal when I remove the power cord but shoots up again when plugged back. This is happening with different power adapters/wall sockets so it might not be a faulty adapter issue. Why is this happening and any pointer to resolve this issue?

• Understanding why a 450W power supply is destroying my ATX motherboards but not mATX

  - by T. Webster

  Maybe I'm missing something really obvious here, but after going through 3 new motherboards in trying to build my new machine, I'm finally certain that the 450W power supply I bought has been destroying them. It seems like it should be simple: just connect the connectors where they fit and switch the thing on. But today after hooking it to my ASUS Sabertooth 990FX TUF Series Motherboard and switching it on, I could see and smell the smoke coming out of the motherboard. What I don't get is why I can hook this same 450W power supply up to my mATX motherboard and not run into the same problem. What am I missing here? Where on the box or manual is this? (I have 8x2 GB RAM, AMD FX-4100 3.6GHz CPU, 1 512MB ATI graphics card, 1 WD 7200 RPM SATA hard drive. )
