• Computer makes hissing noise, turns off after few seconds

  - by Kaustubh P

  I have a problem similar to the questions posted here and here. This is my config: Asus M3N78-EM, with AMD Phenom X3 720 2800 Black Edition, 4GB Transcend DDR2 RAM, Nvidia 9400GT. HD is a 160 GB IDE, and a LG IDE DVD-ROM. The power button is a bit off, I have removed the cover of the switch, and the only way it turns on is just giving the "stick" under the cover a gentle press. It turns on sometimes, and at other times, I have to cut-off the power from the PSU, and try again. I will describe my problem in as detail as possible, please bear with me: The problem has started in the last week, a few months after I changed the to the powerswitch arrangement as described above. The PC makes a hissing noise, and I wasn't able to pin-point the noise source, because of the various other fans. At first, removing the HD, rebooting w/o the HD, turning it off, reconnecting and booting made the problem go away. But of late, it doesn't happen. As suggested in the other questions, I tried reducing the load by disconnecting both the IDE drives, and the problem (noise + turn-off) still occurs. I also connected another 80G IDE HD,today morning, adn it still made that noise, and turned off. I also opened up the PSU, but I couldn't see any fault in that, I tried rotating the fan by blowing into the blades, and with my fingers, but the hissing noise didn't come from there. Or maybe the speed wasn't enough to evoke that noise. A few weeks ago: I had cleaned the Cabinet and had repasted the processor and its fan using some thermal paste. Could that be at fault? I also used a vacuum to blow the dust out of the PSU, could the power have been too much, to maybe offset the fan or something? A label on the PSU says it uses a ball-bearing fan. That only leaves me with the Processor fan and the processor itself. I didn't try removing the processor fan and processor from the motherboard, and then turning the PC on, fearing damage. Will doing so cause any damage? What can I do to localize and pin-point the problem? Also, after a few tries, the Computer starts up. Sometimes it turns of within 2 seconds, sometimes after the POST. Once it turned off at the grub. Another time it booted completely and then turned off. The only way to ensure that the PC wont turn off, is if the hissing noise stops. EDIT: I suspect it to be the Processor/Processor fan, owing to the source of noise. All the config, except for the Cabinet, is just over a year old. EDIT2: I also just remembered, that I had set the "On-power resume" to turn on, i.e. If I supply he PC with power, it will turn itself on, w/o me needing to press the switch. I had done that to workaround the faulty power-switch, as noted above. EDIT3: I calculated the power my system needs, from the antec site, and I just arrived at 292W

• Intermittent lockups, unable to diagnose in over a year

  - by Magsol

  Here's a real doosie; I may just give my firstborn child to whomever helps me solve this problem. In July 2008, I assembled what would be my desktop computer for graduate school. Here are the specs of the machine I built: Thermaltake 750W PSU Corsair Dominator 2x2GB 240-pin SDRAM Thermaltake Tower Asus P5K Deluxe Motherboard Intel Core 2 Quad Q9300 2.5GHz CPU 2 x GeForce 8600 GT WD Caviar Blue 640GB hard drive CD burner DVD burner Soon thereafter, I ordered a new motherboard (because I was an idiot; that first motherboard supported CrossFire, not SLI), an Asus P5N-D. I was originally running Windows XP SP3. Pretty much right into the start of the fall semester, my desktop would simply lock up after awhile. If my system was largely idling, it would be after 1-3 days. If was gaming, it often happened an hour or two into my gaming session, indicating a link to activity level. Here's where it started getting interesting. I started looking at the system temps. The CPU was warmer than it should have been (~60s C), so I purchased some more efficient cooling compound a way better cooler for it. Now it hardly goes over 40 C. Intel was even kind enough to swap it out for free, just to rule it out. Lockups continued. The graphics cards were also running pretty warm: about 60 C idling. Removing one of them seemed to improve stability a little bit...as in, it wouldn't lock up quite as frequently, but still always eventually locked up. But it didn't matter which card I used or removed, the lockups continued. I reverted back to the original motherboard, the P5K Deluxe. Lockups continued. I purchased an entirely new motherboard, eVGA's nForce 750i. Lockups continued. Ran memtest86+ over and over and over, with no errors. Even RMA'd the memory. Lockups continued. Replaced the PSU with a Corsair 750W PSU. Lockups continued. Tried disconnecting all IDE drives (HDDs are SATA). Lockups continued. Replaced both graphics cards with a single Radeon HD 4980. Average temps are now always around 50 C when idling, 60 C only when gaming. Lockups continued. Throughout the whole ordeal, the system has been upgraded from Windows XP SP3 to Vista 32-bit, to Vista 64-bit, and is now at Windows 7 64-bit. Lockups have occurred at every step along the way (each OS was in place for at least a few months before the next upgrade). Edit: By "upgrade" I mean clean install each time. In addition to those reformats, I have performed many, many other reformats of the system and a reinstall of whatever OS had been previously installed in an attempt to rectify this problem, to no avail./Edit When the system locks up, there's no blue screen, no reboot, no error message of any kind. It simply freezes in place until I hit the reset button. Very, very rarely, once Windows boots back up, the system informs me that Windows has recovered from an error, but it can never find the source aside from some piece of hardware. I've swapped out every component in this computer, and there are more fans in it than I care to count...though for the sake of completeness: top 80mm case fan (out) rear 80mm case fan (out) rear 120mm case fan (out) front 120mm case fan (in) side 250mm case fan (in) giant CPU fan on-board motherboard fan (the eVGA board) triple-fan memory setup (came with the memory) PSU internal fan another 120mm fan I stuck on the underside of the video card to keep hot air from collecting at the bottom of the case I'm truly out of ideas. ANY help at all would be oh-so-very GREATLY appreciated. Thank you!

• Right Clicking error in windows 7 windows explorer

  - by Domenik VanBuskirk

  Whenever I right-click something in windows explorer other than favorites, libraries, computer, or network (the main headings in the left pane), the drop-down menu does not appear and an error pops up "windows explorer has stopped working" - "windows explorer is restarting". Once those both close the icons on the desktop and taskbar itself blink off and back on again. Is there any way of finding out what is going on when I right click and this problem ensues?

• Why are my hard drives failing?

  - by WishCow

  I have a small Ubuntu server running at home, with 2 HDDs. There are two software raids (raid1) on the disks, managed by mdadm, which I believe is irrelevant, but mentioning it anyway. Both of the HDDs are Western Digital, and have been used for around 2 years, when one of them started making clicking noises, and died. I figured that maybe it's natural after 2 years, so I bought a new one, and resynced the raid arrays. After about a month, the other drive also died. I didn't get suspicious, since both drives have been bought at the same time, it's not that surprising to see both of them near each other, so I bought another one. So far, 2 old drives failed, and 2 brand new in the system. After one month, one of the new drives died. This is when it started getting suspicious. Since the PC was put together from some really old parts (think AthlonXP), I figured that maybe the motherboard's SATA controller is the culprit. Of course you can't switch parts easily in an old PC like this, so I bought a whole system, new MB, new CPU, new RAM. Took the just failed drive back, since it was under warranty, and got it replaced. So it is up to 2 failed drives from the old ones, and 1 failed drive from the new ones. No problems, for 1 month. After that errors were creeping up again in /var/log/messages, and mdadm was reporting raid array failures. I started tearing my hair out. Everything is new in the system, it's up to the third brand new HDD, it's simply not possible that all of the new drives that I bought were faulty. Let's see what is still common... the cables. Okay, long shot, let's replace the SATA cables. Take HDD back, smile to the guy at the counter and say that I'm really unlucky. He replaces the HDD. I come home, one month passes and one of HDDs fails, again. I'm not joking. Two of the brand new HDDs have failed. Maybe it's a bug in the OS. Let's see what the manufacturer's testing tool says. Download testing tool, burn it to a CD, reboot, leave HDD testing overnight. Test says that the drive is faulty, and I should back up everything, if I still can. I don't know what's happening, but it does not look like a software problem, something is definitely thrashing the HDDs. I should mention now, that the whole system is in a shoebox. Since there are a load of "build your own ikea case" stuff, I thought there shouldn't be any problems throwing the thing in a box, and stuffing it away somewhere. The box is well ventilated, but I thought that just maybe the drives were overheating. There is no other possible answer to this. So I took the HDD back, and got it replaced (for the 3rd time), and bought HDD coolers. And just now, I have heard the sound of doom. click click whizzzzzzzzz. SSH into the box: You have new mail! mail r 1 DegradedArrayEvent on /dev/md0 ... dmesg output: [47128.000051] ata3: lost interrupt (Status 0x50) [47128.000097] end_request: I/O error, dev sda, sector 58588863 [47128.000134] md: super_written gets error=-5, uptodate=0 [48043.976054] ata3: lost interrupt (Status 0x50) [48043.976086] ata3.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen [48043.976132] ata3.00: cmd c8/00:18:bf:40:52/00:00:00:00:00/e1 tag 0 dma 12288 in [48043.976135] res 40/00:00:00:4f:c2/00:00:00:00:00/00 Emask 0x4 (timeout) [48043.976208] ata3.00: status: { DRDY } [48043.976241] ata3: soft resetting link [48044.148446] ata3.00: configured for UDMA/133 [48044.148457] ata3.00: device reported invalid CHS sector 0 [48044.148477] ata3: EH complete Recap: No possibility of overheating 6 drives have failed, 4 of those have been brand new. I'm not sure now that the original two have been faulty, or suffered the same thing that the new ones. There is nothing common in the system, apart from the OS which is Ubuntu Karmic now (started with Jaunty). New MB, new CPU, new RAM, new SATA cables. No, the little holes on the HDD are not covered I'm crying. Really. I don't have the face to return to the store now, it's not possible for 4 drives to fail under 4 months. A few ideas that I have been thinking: Is it possible that I fuck up something when I partition and resync the drives? Can it be so bad that it physicaly wrecks the drive? (since the vendor supplied tool says that the drive is damaged) I do the partitoning with fdisk, and use the same block size for the raid1 partitions (I check the exact block sizes with fdisk -lu) Is it possible that the linux kernel or mdadm, or something is not compatible with this exact brand of HDDs, and thrashes them? Is it possible that it may be the shoebox? Try placing it somewhere else? It's under a shelf now, so humidity is not a problem either. Is it possible that a normal PC case will solve my problem (I'm going to shoot myself then)? I will get a picture tomorrow. Am I just simply cursed? Any help or speculation is greatly appreciated. Edit: The power strip is guarded against overvoltage. Edit2: I have moved inbetween these 4 months, so the possibility of the cause being "dirty" electricity in both places, is very low. Edit3: I have checked the voltages in the BIOS (couldn't borrow a multimeter), and they are all seem correct, the biggest discrepancy is in the 12V, because it's supplying 11.3. Should I be worried about that? Edit4: I put my desktop PC's PSU into the server. The BIOS reported much more accurate voltage readings, and also it has successfully rebuilt the raid1 array, which took some 3-4 hours, so I feel a little positive now. Will get a new PSU tomorrow to test with that. Also, attaching the picture about the box: (disregard the 3rd drive)

• Desktop PC does not power up on power button

  - by hIpPy

  When I press the power button on my desktop, it does not power up completely. Before I press the power button, I see lights on the motherboard. Everything is normal. On power button press, the fans on the cpu, graphics card and motherboard start to spin a little for a second or two and then they stop. No beeps during this process. It has been doing this for a while now but it used to start up after some trials. Once it starts up, I have NO issues at all like random shutdowns so it is not an issue with OS. I'm just guessing here but it seems as if the PSU (Antec TP2-550ATX) is dying out and does not have enough power now - just a guess. It's an old desktop assembled in 2005 but I have maintained it well. Any ideas? Please help. Thanks. Below is the complete configuration.

• PC freezes after repeated clicking noises

  - by Péter Török

  I have an oldish PC (Athlon XP 2200, WinXP). Every time I switch it on, I hear a loud "click" first of all, and when it is shut down, again a click is the last sound I hear. Lately it started to behave erratically: it started to click loudly in the middle of a session. First only once in a while, then repeatedly for several seconds in a row, and finally it froze completely. We were not doing anything particular during these times, usually just browsing the web. This has already happened twice in a few week's time period. We typically use it only in the evenings, so when the freeze happened, I just decided it is time for the bed. When it was started up the next day, everything looked fine. Any hints on what could be the culprit? Could it be caused by an ageing heat fan, or dust that has accumulated inside the case? We are backing up all the data stored on it, and then will open the case to look inside, but I thought it would be good to get some background info first of all.

• Intel RST accidentally selected wrong drive as system drive -- how to fix?

  - by Sean Killeen

  Question / TL;DR If Intel RST has marked a drive other than my RAID set as the system drive, how can I get it so that the RAID set is now seen as the system drive, and catch it up to my drive now? What Happened NOTE: Some perhaps unwise decisions are ahead. This is as best as I can recall the order of things. I had a 2x1TB RAID1 config. I bought the drives around the same time, and they started to die around the same time. I replaced 1st drive with a 2 TB drive before the other one's SMART errors got more serious. I waited for the RAID to replicate, then replaced the 2nd drive with a manufacturer's replacement. I got a second manufacturer's drive replacement and used it as a spare. so I now I had a 1TB/2TB drive in a RAID1 and another 1TB as a spare. The 1TB drive in the replacement set was bad from the manufacturer. Rather than mess with their refurbished stuff, I bought another 2 TB drive an upped the config to a 2x2TB RAID1 with the other, functioning manufacturer's drive as a spare. I made the mistake of trying to bring the other drive online to clean it out and the signatue clash killed my machine. When the machine rebooted, that drive was marked as the system drive. So, I have a 2x2TB RAID1 that is apparently offline, and 1 spare 1 TB refurbished drive that everything is being run from. Not a great idea. Options I'm considering Bring the 2x2TB drive back online, and then unplug the spare until I can format it in another system. This would involve some data loss, but the more I think about it, I actually think I haven't modified any data that isn't backed up or synced somewhere (go me!) Anything that isn't is likely trivial, enough that I'm willing to take the risk. One downside here is that if the 2 TB doesn't have data on it for some reason, I could be screwed trying to put the other drive back in, no? Try to somehow get the RAID1 updated with the data from the current system drive. Option 3?

• Dell Studio 1555 not starting up

  - by Abhishek

  This is a 3-year-old laptop. I never had a big problem with it until now. I updated Kubuntu the night before yesterday. And Firefox got updated to version 18 and a few other related packages got updated. Then I shut down the laptop and restarted it, but it failed to start. I could hear the fan and the hard disk and the optical disk drive initialize. And the power button also lighted up. But there was no video - no POST or BIOS menu. I even opened the laptop up to the point when only the motherboard was the only thing attached to the base cover. I took it to the technician this evening. He checked it casually, and said that it might be a motherboard problem and will cost quite a bit to fix. Though he was not sure and said that he will give me a call after confirming the problem. Has anyone else had the same problem? What was it and what was the fix?

• OS X will not register newly installed network adapters

  - by Chris

  I have purchased an Edimax 7318USg and tested it on a Windows machine (works). The installation process for the software for this adapter runs smoothly. However, OS X simply does not recognize new network adapters. When you go to System Preferences/Network, a new network adapter should be present/there should be an alert. This is not the case. Why might this be? Is there a setting I may reset to force the operating system to recognize this? Thanks!

• What could cause a lag in typing with WinXP?

  - by Ssvarc

  I'm working on a Dell Vostro 1000 laptop that has a mysterious lag in typing. You enter keystrokes and it takes a while to show up on the screen. WinXP Pro was freshly installed and the behavior is still here. Here is the weird part... I've tested the computer with the full Dell diagnostic suite, Prime95 (using UBCD4Win), and Memtest86. Everything checks out as fine. If I run a LiveCD such as UBCD4Win or Ubuntu (9.04?) then there is no typing issue. This is causing me lots of aggravation. Thoughts?

• terminal tools and logs for debugging TCP issues

  - by kellogs

  I have a server which I am testing for functionality (not load, not stress) with tsung. 50 users / second, 100 total users. Judging from tsung (tsung is the testing framework) graphs, there TCP connections (red line) drops to 0 while the commenced user sessions (green line) does not. Server logs show nothing to be gripping onto, so I am speculating some kind of TCP issue. Should this be the case ? Where would I look further on the server, any logs / tools to be looking at ?

• Cobalt Qube 3 Unresponsive

  - by Devin Gund

  I recently bought a used Cobalt Qube 3 server off of eBay. The seller listed it as working before it was shipped. After starting it up for the first time, the "Cobalt Networks" logo scrolled across the LCD screen (this is normal), but then it stayed there. It will not go away, and the server will not respond to any of the buttons besides turning it off. I read the manual, and it does not say anything about this normally occurring. If necessary, could anyone walk me through or provide links to a reset tutorial? I have the OS Restore CD. Please help? I'm not sure why my question is being downvoted but if you need any more information please comment.

• Partition table corrupted (USB flash drive)

  - by 13ren

  It's an 8 GB Patriot thumb drive, which I've used extensively with lots of data. Today, it is detected, but all data is gone: (EDIT at least some data is still there, but the partition table is gone) EDIT @Sathya (thanks) here's the relevant output from sudo fdisk -l: Disk /dev/sdc: 8019 MB, 8019509248 bytes 247 heads, 62 sectors/track, 1022 cylinders Units = cylinders of 15314 * 512 = 7840768 bytes Disk /dev/sdc doesn't contain a valid partition table It looks like it is /dev/sdc, with that 8 GB... and no partition table.

Another option is "[ MBR Code ] Write TestDisk MBR code to first sector" - would it be better to do this? EDIT I found that at least some of my data is still on the flash drive, by using the below, and searching for English text in less (like " the "): cat /dev/sde | tr -cd '\11\12\40\1540-\176' | less (The drive changed from "/dev/sdb" to "/dev/sde" because I connected some extra drives today). I've learnt that "/dev/sde1" would be the first partition; and "/dev/sde" is the whole drive. Because unix treats these devices just like files, you can use all the ordinary unix file commands on them, like cat, and then process them like any other stream of data. The tr above removes non-printable characters ("\40" is space, which I wanted to preserve). In less, you can use "/" to search, similar to Vim. How can I get my data back (assuming it's still there)? If only the partition table is corrupted, is there a standard "partition recovery tool"? Is there a way to "repartition" without deleting everything?

• [Mac OS X] Terratec Cinergy Hybrid T USB XS is not recognized anymore

  - by Gabble

  I have used Terratec Cinergy Hybrid T USB XS for years now, alongside with Elgato EyeTV software. I am a happy and completely satisfied user! Since a couple of weeks the USB sitck stopped working on my MacPro1,1 (OS version 10.6.3): EyeTV does not see any device attached, and actually, the green led on the stick stays off. 1) it is not a USB port fault: I have unplugged any other USB/Firewire device and tried with different USB ports, to no avail (any other USB devices work as expected on any port) 2) I have completely uninstalled EyeTV software, including preferences and system daemons/extensions, rebooted and reinstalled the latest EyeTV. No way. 3) reset the PRAM. Nope. 4) checked the Apple System Profiler - USB: No device attached, The MacPro does not see it at all. ============= I need to say that: a) the device worked as a charm even with the latest OS 10.6.x (so it's not a OS upgrade cause) b) I have plugged the Terratec Cinergy Hybrid T USB XS to my MacBook5,1 where EyeTV is not installed and was never installed: The green led on the stick turns on, the growl bubble pops up, and the device is perfectly recognized by the system. Apple System Profiler says (sorry, Italian language): Cinergy Hybrid T USB XS (2882): ID prodotto: 0x005e ID fornitore: 0x0ccd Versione: 1.10 Numero di serie: 061102005755 Velocità: Fino a 12 Mb/sec Produttore: TerraTec Electronic GmbH ID posizione: 0x04100000 Corrente disponibile (mA): 500 Corrente necessaria (mA): 500 At this point I am pretty sure the Terratec stick is not damaged and there is something wrong with my MacPro. I kindly ask you: Is there a way to force my MacPro recognize the USB device? What can I check? Is there something that caches USB connection that can be reset? A OS reinstall would be the very last resort for me… Thanks in advance for any help you will offer!

• How do I troubleshoot computer dumps?

  - by KronoS

  Once I have a dump of a computer crash/freeze, what are some tools and steps to take in order to troubleshoot crash based off of the dump itself? I am looking for tools to isolate what processes or issues are causing the crash, and also good techniques in troubleshoot the actual dump itself. Once I've determined what the "troublesome" process has been, what do I do to troubleshoot the issue? For example if I determine process foo.exe or bar.dll etc, is the problematic file how do I determine what can be done?

• Windows 7 Locking up Randomly

  - by Michael Moore

  I've got a Windows 7 machine that is locking up randomly. It can be in the first thirty seconds, or it can be hours later. There is nothing specific I can find that is running when it happens. When it locks, the screen doesn't change, but nothing moves. The waiting icon stops, the mouse stops, keyboard doesn't work, etc. I've even tried the crash on ctrl-scrl registry hack, and it won't even dump the kernel. I've run hardware diagnostics on the RAM and it doesn't find any problems. I would think it is a hardware issue, but on this exact same machine, I can run 64 Bit Ubuntu and it has zero problems. I've even tried reinstalling Windows7 from scratch, and it still happens. Anyone have any ideas? Any good diagnostic tools to recommend? Thanks! Michael

• Windows 7 systeminfo reporting incorrect System Boot Time?

  - by rdingwall

  I work 9-5 and switch my PC off when I leave the office each day. When doing timesheets I need to know what time I got to work, so I usually use cmd systeminfo for finding the System Boot Time. Since upgrading to Windows 7 however, it's started reporting bizarre numbers between 11pm-2am instead of 8-9am. Today it says it booted at 11:34pm last night! I checked the event log and there is no entries between when I shutdown at 5:30pm yesterday and booted around 8am this morning. Has anyone else encountered this?

• Monitor goes black for a few seconds

  - by privatehuff

  I have a Hanns G 28" monitor, Model # HG281D It has its issues (viewing angle sucks) but has been functional and solid, great for desktop stuff. Worked without any sign of any problems for 6-12 months. However, now the monitor "goes black" for about 2-3 seconds, almost like when you click "detect display" It does not turn off (power light does not go amber) The computer is completely unaffected and the video mode never changes when the picture returns. The computer is fully responsive and will keep playing music or taking my keypresses during the time I can't see anything. (it just happened and I kept typing, etc) It happens on multiple computers across several operating systems. (I have an 8-port iogear KVM switch that has several computers connected) But, it seems to happen only on certain computers. I have a hackintosh that does it, a windows 7 PC that does not, a lenovo laptop that does not, and my old ubuntu 8.10 box did not do it, but my new mint 8 box does do it. I've check the connections and tried changing out the power cable and the vga cable. Sometimes it won't happen for hours (or days) and sometimes it happens several times per hour. It was happening many months ago, did not happen for months, and has now started happening again. Does this make any sense? What could it be?

• Unable to logoff, disconnect, or reset terminal server user in production environment

  - by l0c0b0x

  I'm looking for some ideas on how to disconnect, logoff, or reset a user's session in a 2008 Terminal Server (unable to login as the user either as it is completely locked-up). This is a production environment, so rebooting the server or doing something system-wide is out of the question for now. Any Powershell tricks to help us with this? We've tried to disconnect, log the user off and reset the session as well as killing the session's processes too, directly from the same terminal server (from the task manager, Terminal Services Manager and the Resource Monitor) with no results. Help! UPDATE: We ended up rebooting the server as no other attempts that we could think of worked. I'll leave this question open hoping someone might have more information about this one issue, and it's potential fixes

• How do you troubleshoot Family Safety reports

  - by Klas Mellbourn

  I have set up Microsoft Family Safety in Windows 8 for my daughter's account. At first I got meaningful reports via e-mail each week. But then the e-mails started reporting no activity, even though my daughter still uses the computer. The e-mails are still sent to me, but indicate that she is not using the computer at all. Family Safety is definitely still active on the computer. It limits how long she can use the computer. So only the e-mail reports are buggy. I don't know how to troubleshoot this since the e-mails are generated by Microsoft. Any ideas?

• MacBook Pro screen goes dark

  - by Mike M

  I've had my MacBook Pro for two years now; no problems so far (it has had 3rd party RAM from the get go). Today, I'm copying a particularly large VM from an External disk drive to local MacBook disk. It has about 3GB to go and I take off to do some other things and when I come back my screen is "dark". The computer is still on but I can't see anything. I forced a reboot by holding down the power button, it starts up with the "chimes", but still no screen. I've done this several times. Any ideas? Do you think the hard disk activity caused it to get too hot?
