    Default Computer randomly restarts

    After the accident I had with my PC, Im using it again.

    So while I was using it, the machine would just randomly restart. After a while i was able to reach Windows, but then the computer just suddenly restarted. After it turned on I was lucky and I got to Windows, and then I shutdown the computer while it also updates.

    After a while I start the computer and now I just cant reach Windows, it would either freeze when it's on the 'Windows XP loading' phase or it would just randomly reboot.

    anyone know ta hell happend to my computer??

    Actually I do know what is happening to it. My computer had the same problem. It's a virus. There is an easy way to get rid of it, but it was a while ago so I don't remember the specifics. If you google it you should find the cure easily.

    If you're lucky, yes.

    Random restarts can be a sign of unstable power supply / regulation, overheating problems, and a host of other things, including software problems (such as a virus).

    First, try resetting your BIOS to its default settings (usually there's an option to "restore to factory defaults" or something along that line in the BIOS). See if that solves the problem.

    If a reformat doesn't do the job, then most likely it's a hardware problem.

    Edit: OK I read your prev. thread. Try with a new power supply. If you managed to blew the power supply with some cables connected to the mainboard, it's possible you've fried the chips on the mainboard too. I'm pretty sure its related to unstable power regulation.

    One advice: don't be afraid to spend money on power supplies with a good brand reputation. Even though you can get a 600W PSU for $30, it's not a good idea to get that.

    I already have a new power supply, so does that mean that if im that unlucky I may have to buy a new mainboard?

    As they said, it could be any one of a number of things.

    For example:
    Open your case and turn the computer on. See if any of your fans are broken, not working. Also, pull off your CPU cooler's heatsink and reseat it with premium thermal paste, those could also be the problems.

    Or, it could be that the thermal sensor for the CPU temp is on the fritz.

    Or, many other things.

    On thing you could do, though, try this:
    In the BIOS, set the boot priority to CD as first, then put in your OS cd and start the computer up. Leave it running for a while in the setup menu. If it shuts down, then we know it has nothing to do with bad software, and only hardware. For example, bad mobo, bad power supply, bad ramstick, bad cooling fan, badly put on heatsink, etc.

    Bit of a weird way to go about doing that, but it should work to eliminate 50% of the possible problem possibilities.
    Edit: Yeah, there are probably more "elegant" ways of checking to see if it is a hardware(my money is on this) or software issue, but at 1:30 am, those escape me, sorry for the strange ideas.

    I had a run at it today and this is what happen

    So I turn it on and it starts normally, I even got to the desktop. So the prompts started happening MSN popped up, AVG popped up, etc......
    After all that I opened up My Computer while i got my USB stick plugged in, then it rebooted.
    After that I tried to get to run it properly but to no avail. I also checked the fans (both the PSU's and Processor's), they were working fine.
    I also went to the BIOS and changed the setting to Default, after all this its still restarts.

    btw on my 1st run I found out I have a few viruses, im not sure if this is linked to the problem but it might help

    Mmm.. Try booting in safe mode. To do this if you can't get to Windows, right after the BIOS prompt is done, press F8 like crazy till a boot menu pops up. It should give you an option to go to safe mode. If everything is normal in safe mode, then you can assume that your hardware works fine.

    If you're willing to take it a step further, get some kind of Live CD / DVD. These are disks with OS within them that can run directly off the CD / DVD (thus is definitely free from any viruses you might still have on your hard drive) provided the CD / DVD itself is clean from viruses. A lot of Linux install CDs/DVDs have this feature (look up Ubuntu or Knoppix). Download the .iso file, and make bootable CD / DVD out of it.

    If running the Live CD/DVD still causes restarts.. well, time to shell out more money...

    The only way to know if your mother board has a problem is if you test another different hard disk on it. If problem does not occur then your hard disk may be faulty or is infected.

    If the board has the problem, check the power supply, check if the RAM displays the same memory capacity when booting, also check the other cards(LAN, internal modem, sound crad etc.)these maybe shorting your board, and check your keyboard if its working properly.

    Also check your UPS/AVRs because the problem starts there, if involuntary shutdowns are experienced.

    If your windows is infected, the last resort and best solution would be to "clean" format it.

    Well, first i say i'm sorry to butt in but I have similar problems too. So rather that i make a new thread, i borrowed this thread ^_^. I bought a GeCube Radeon X1650 AGP series ( with 256 MB DDR3 ). In my old motherboard ( Abit KV8 Pro ) it just freezes after some minutes when i starts up my PC. So my local compu-shop tell me to replace the mother board. i replace it with an Epox MB ( i only remembered that it use an NForce 3 chipset ).
    The result is my system restarted rather than freeze, i used a new stabilizer, installed the newest Catalyst driver. And it lasted for a month or so. ( and at that time i could play NWN2 and Oblivion ).
    The problem occured a week ago, it started to freeze or restarted. What bugs me is that it can even freeze before the windows start up screen. it can freeze on BIOS menu, on the first screen showing our RAM and other things. Have u guys have the same experienced. I suspected that my Power Supply is at fault but i just needed to be sure. The strange point is sometimes it doesn't restarted or freeze. It can works smoothly ( mostly the cases happens at the morning ), for several hours of gameplay and movie watching.

    Oh and i wanted to ask, if my Windows is at fault ( because a virus or some sort ) could it trigger the same symptoms like i experienced ( the BIOS freeze, Freeze at the VGA bios startup )? Really this things make my head ache T_T.

    And sometimes there is a report when my window restarted smoothly that there have been an error occured on my windows. Something to do with database i think or the extension is XML. Any body can help me?
    LONG LIVE HIME-SAMA. MY LIFE FOR RUMBLANDIA!
