• PC powers up but there is no display

  - by Matthew

  I built a computer with standard components I bought from Newegg about three years ago. It ran great for 2 years and has sat powered down for the last year. I tried to power it up today and the display was blank. It powers up, lights come on, drives start spinning but there is nothing on the display. I verified that the monitor and video adapter work. I also tried the video adapter in a different slot on the mother board with no luck. What's the next thing I should try? Is the mother board shot? Thanks.

• Proper way to connect SATA and IDE Hard drives together?

  - by Bartek

  I have an old IDE hard drive that has a broken Windows install on it. It just won't boot up, and I've tried a variety of solutions. That's fine, I really just need a few files on the hard drive. I have a computer that uses a SATA connected hard drive. It's a working PC. I would like to connect the old IDE hard drive to that compute and basically browse through the file system, grab the files, and copy them to my existing computer. My problem is with my few attempts to connect the IDE drive I would get Boot Disk Failures and so forth. I guess it's trying to boot from the IDE but I'm not really sure. Any help would be appreciated, Thanks!

• How to redirect sound to USB headset when plugged in?

  - by LM

  I often have to switch between audio output from my speakers and my headset (P5Q mobo with integrated sound and Microsoft headset). I've already got it so that when my headset is plugged in, sound will be played through it, and if it isn't, sound will play through my speakers. The problem is that if I have a game or similar program started while my headset is plugged in, if I unplug it, I will get no sound. Also, if I start the program with no headset, and plug it in, I get sound still through speakers. Is there any way to do this?

• Upgrading HP DL185 G5 8LFF, is using a Dell J1520 4-Drop SATA Adapter possible?

  - by jpreed00

  The HP DL185 G5 8LFF model supports 8 3.5" drives and 1 optical drive. However, instead of the optical drive, I'd like to have 2x 2.5" drives instead. The problem is that the PSU has no more SATA power cables (even though the motherboard has 4 additional SATA data ports). The PSU does have a free 10-pin connector and it looks like the J1520 cable from Dell would fit the bill. Link to cable description Does anyone have any experience using these cables? Are they safe? Any other ideas for adding the disks to the server if I don't use the cable? Thanks!

• Upgrade no raid server to raid

  - by AZee

  I have just learned that our PDC has a single drive with 2 partitions. I also know that this drive has bad blocks as recorded in the event log. What I would like to do is to convert this to a RAID solution with a nice balance between economy and performance. I will admit that I have only configured servers with RAID from scratch, and have no experience upgrading an existing system into a RAID system. In fact, I'm not sure it is even possible. Since this is the PDC for 350+ workstations downtime is important. I'd like to hear from other System Administators how they would tackle this and their recommendations for all devices. At this time it seems to me that I can replace the existing drive and then restore from backup or install a controller, drives, configure the RAID an basically start from scratch. Thank you for taking your time. ~AZee

• sata2 hdd not reported correctly on gigabyte mobo

  - by hyperboreean

  hey guys, I have a gigabyte ga-k8nmf-9 mobo which has both sata 1 and sata 2 support. Until a few hours ago I had a samsung 160gb sata 1 hdd which worked ok until it failed. I bought a wd se16 caviar, 500 gb, 7200 rpm, 16 mb cache, but it seems that it's not properly detected by my computer - it's only showing 137 GB out of 500. I tried a BIOS update (to F10e) and it's still doing the same thing. I've altered BIOS settings to use only sata (no ide) and many other settings, but nothing worked. Any help will be greatly appreciated Update on this one: it seems that the previous hdd was doing the same thing, though I didn't notice because it was approximately the same size

• Microsoft Wireless Keyboard 3000 v2.0 not working, but paired Wireless Mouse 5000 on same receiver does?

  - by John Straka

  I have a Microsoft Wireless Keyboard 3000 v2.0 that was bought paired with a Microsoft Wireless Mouse 5000. They're both Bluetooth and use the same receiver. The keyboard no longer works. The receiver is fine, as the mouse still works. The keyboard is still detected by Windows when the receiver is plugged in. The batteries have been replaced. There are no on/off switches on the keyboard or mouse, and no re-sync button on them or the receiver. Results are the same when using the receiver in a different USB port, or on a different machine. Anything else I might try to fix this, or should I hold a funeral for the keyboard?

• Where can I find this HP modular keyboard or similar?

  - by Chaos Whistler

  I'm looking for an HP USB 104-Key Modular Keyboard with Detachable Number Pad (model number is DT530A, I believe), shown at this online store, where it's quite cheap but is sadly sold out. I've searched for hours on Google, and I've found several - the problem is they're Spanish or Greek keyboards but I need one in English (US keys preferred)! I would also be happy with a keyboard which is not exactly this but is similar, either with a detachable keypad or with no keypad at all, as long as the keyboard key layout and positioning is the same as on a standard keyboard. Can you help me find such a keyboard?

• How long until the chirping stops or what can I do to make it stop?

  - by MadBurn

  I know computers, I have been fixing them and building them for over a decade... but I don't know the exact electronics of them. My personal desktop PC is making an irregular, but constant, extremely high pitched chirping noise. I know this could be my hard drive, but I've heard that noise before and I believe this is a capacitor or part of the electronics. This noise is right at the edge of my hearing and I can feel it more than I can hear it. After a while, it starts to give me a headache and makes me physically sick. How long will this last? Is there anything I can do to fix it (short of replacing the entire motherboard)?

  We are currently protecting our software with a USB dongle, but we would like also to store the application itself on it. I'm sure something like this exists, but we haven't be able to find it.

• What's the most durable netbook

  - by Keyslinger

  I'm about to spend more than two years in Latin America and I know from experience that not all computer equipment can handle the shifts temperature, air moisture, and other atmospheric variables as well as the generally greater number of shocks and jostles presented by developing-world transportation and unstable infrastructure/power grid. Is there any particular manufacturer, brand, or model of netbook or notebook that stands above the rest in terms of durability and ability to survive in harsh environments?

• I think my laptop just died

  - by Joel Coehoorn

  I have a Dell 1330M that as of about 15 minutes ago will no longer POST. What happened was I was working, stepped away for a moment, and when I came back it was turned off. I thought that was odd, but turned it on and things seemed fine. About 1/2 hour later it crashed and restarted, but came up fine again. It did this once more. At this point I was starting to get worried, but I hadn't had any problems with the laptop before and every crash was after doing some work in a virtual machine that I don't often use, so I at put the blame there. It didn't feel like it was overheating anywhere and there's no ozone smell of overheated electronics. Then it crashed a final time and now when I turn it on all I see is a bright screen with a bunch of vertical lines (noise). I've tried removing the memory sticks one at a time, but I get the same result with either memory stick in either slot. With no memory at all it stops earlier in the POST process and the screen is completely blank (black, no backlight). As I type this, I hear a double beep from the system about once every 10 minutes. I'm pretty sure the hard drive is fine because it fails during post, before anything off the drive is needed. The power supply seems good because the screen is nice and bright. It's not the RAM because swapping that around made no difference. The leaves motherboard (which I doubt and can replace) and CPU (which just might be changable). Any ideas? Is there any hope for this laptop? I'm rather fond of it and I'd have a hard time replacing it with anything near as nice.

• toshiba a200 laptop hangs/freezes when plugged in

  - by tapan

  The subject says it all. It is the exact same problem as described here. I had asked a similar question before here. My system specs etc, everything is here. My problem is just that I cannot afford to get it fixed right now. I just need for the laptop to be kind of usable for 2-3 more months. It worked perfectly for 3 months or so in ubuntu recovery mode. Now it hangs/freezes every hour. I spend 8 hours a day on an average on my laptop. So i just want it to last at least that long. If the laptop is not plugged in in recovery mode / regular ubuntu mode, it freezes in 5 mins and the screen becomes all weird. With my windows 7 OS, it works perfectly on battery but hangs instantly as soon as it is plugged in. Also now, a high cpu usage doesn't help anymore. Any strategy or suggestions i could employ to extend the duration for which it doesn't freeze ?

• Complete machine freezes...at a loss

  - by user28818

  Guys, We built around 12 machines a few months ago to run Ubuntu. They each have the following specs: ASUS Z8NA-D6 motherboard Dual quad core Intel(R) Xeon(R) CPU E5520 @ 2.27GHz OCZ Mod Extreme Pro 500W power supply 12 GB Kingston RAM Nvidia GeForce 9800 GT graphics card My machine ran well for awhile. However, it started experiencing random lockups. These lockups are not X lockups, they are complete system freezes. The nic stops responding, the magic sysrq buttons won't work. The machine is dead. I first suspected RAM. Memtest86 didn't find anything, but I replaced the RAM anyway. Still, lockups. So I replaced the graphics card. Still, more lockups. They became more and more frequent and started to happen 2-3 times a day. So I replaced the motherboard and power supply in one fell swoop. Suddenly, no more lockups! Woohoo! Except, a week later, in the morning, the machine wouldn't wake up. I reset it, started it up, and the log files showed the last entry at around 11 pm the evening before. This has started occurring with more frequency...now just about every morning I come in, the machine is locked up, and has been since the night before. Yesterday, in the 3 weeks since I replaced the motherboard and power supply, the machine actually locked up on in in mid-work. This is the first time since replacing the two (MB and PS) that this happened while I was using it. All others occurred while I was away. I'm at a loss. Nothing is in syslog or message that would indicate a problem around the time of the lockup. Temps are good...I use lmsensors to monitor and have a script that writes the output to file every minute. They never get that high. The only thing I haven't replaced at this point is the case and the harddrives. I doubt either could be the cause. What would you do if you were in my shoes? Is there a troubleshooting approach I'm missing? For the record, all of the other machines, all eleven of them, don't have any problems. They're all running the same version of Ubuntu (Lucid) that I am. Thanks!

• USB port causing device problems after new motherboard upgrade

  - by enbuyukfener

  I'm looking into a PC with an issue with one of the front USB ports (perhaps both). It was working before a motherboard upgrade but since then, a USB drive was inserted, overheated and does not appear to be working. Then a phone (with USB charging) was plugged in, and the phone OS suspended. Removing and re-inserting the battery led to the phone (and hence battery) working, however the battery no longer charges (including with a wall charger). It seems too much to be a coincidence and am wondering what the issue may be? Ideas so far are short circuiting, or over-current to the USB ports. Note: Did not occur to me, so details are not 100% accurate or complete. Feel free to ask for missing info that I may have forgotten though.

• Audio switch with multiple 3.5mm input & outputs

  - by David Nguyen

  I've been searching for a device that simple allows me to pick one input and one output from multiple input/outputs. I thought this would be a called a switch but I can only find ones with one input. Is there such a device that can do this? I will be attaching various devices, i.e. multiple console sound, PC & Laptop inputs and outputting to my speakers or headphones. I'm looking for something small and simple. All inputs and outputs are 3.5mm.

• How is fire spread in server rooms and datacenters?

  - by sharptooth

  Every now and then I read that a severe fire has happened in some datacenter, lots of equipment has been damaged and customers have gone offline. Now I wonder what is there to support and spread fire? I mean walls in a server room usually have little or no finish. Racks are made of metal. Almost all units have metal cases. Cables have (or at least should have) insulation of materials that don't spread fire. What is spreading fire in a server room or datacenter?

• New harddrives failing within weeks.

  - by Jason Kealey

  I've experienced 8 hard disk failures in 3 months and have tried many things to solve the issue permanently but I have failed. I would like to know if you have any advice for me. System was running Win XP on an Asus P5W-DH Deluxe. I have setup a RAID-1 array. I started out with 2 x 500 GB 7200RPM Western Digital drives. One died. I took it out to RMA it. On the same day, the router was fried. Assumed a power surge occurred; connected an older UPS to protect the system. Once I got my hands on an identical disk, I installed it. The RAID array was rebuilt. A few days later, the other one died. Assumed the rebuild caused it to fail. Took it out for RMA. Before the other one arrived, the remaining one died. I then discovered I could re-enable them using the Intel Matrix Storage Manager. I re-enabled both and the system seemed fine for a week, until both died again. I got two new 1.5 TB 7200RPM Seagate drives and re-installed Windows 7. Also replaced the UPS and power supply. They both died again. The voltage on the plug is stable between 120 and 122V as per the UPS. None of the other devices have had any problems (monitors, etc.). At this point, I see two options: a) electrical issue in the house that was, for some reason, not blocked by the UPS. b) something else inside the system causing surges? motherboard? onboard raid controller? Failures happen fairly quickly, between 2 and 14 days after I fix the previous issue. I just gotten a new computer (Core i7) to replace it. If it is stable, I can determine that b) was the problem. If it fries its hard drive again, I can determine that it is an electrical issue in the house. Do you have any other thoughts? Any tools I can run on the drives that failed to get more information about the original SMART event history?

• How to use dedicated video card instead of onboard?

  - by Mathias Lykkegaard Lorenzen

  Hi there! I tried running DxDiag (DirectX diagnostics), and I noticed that my graphics card is set to the onboard one that comes with the Core i5 processor (some Intel HD stuff). On my computer, I also have a dedicated graphics card (an Nvidia 310). No serious gaming stuff, I know - just for programming. However, I would still love to know how to switch to that dedicated graphics card instead. My laptop is an MSI CX720.

• Client PC not booting when certain TFT plugged in - TFT or graphics card failure?

  - by Chake

  here comes something quite strange: On a client machine (DELL Vostro 420) we experienced problems when booting: when turning on the machine beeps normal but doesn't display anything and doesn't boot. After some testing I found out, that this only happens if one (of the two) monitors (Iiyama ProLite E2472HDD) is plugged in while booting. If the other monitor (TFT 2) is plugged in everything is fine. Here a small illustration, TFT 1 is the bad guy: TFT 1 | TFT 2 | failure x | x | x x | | x | x | After BIOS-Phase I can safely plug in TFT 1 and everything works just fine. The question is, what can be done to avoide this behavior: Change monitor? (Iiyama ProLite E2472HDD) Change graphics card? (GeForce 9800 GT) Other suggestions?

• Configuring a monitor's contrast/brightess/colours/etc

  - by DMA57361

  I have recently bought myself a new monitor, now I'd had my previous screen well over 5 years now so I'm looking at this one thinking the picture doesn't quite look right (not bad, just different). Rather than just wait until I'm used to the new picture I'd rather get it fine tuned, then get used to it - so I can reap the maximum benefit. So, can you please suggest reliable ways of configuring an LCD monitor's brightness/contrast/colour/etc to provide the optimum possibly quality image?
