Not sure if this is the right place to post this, but I've got a bit of a problem. Every time I switch on my computer- I've had it for about four years, it's fine for a few minutes, if a bit slow and then restarts itself with no warning. It started doing this two days ago, completely out of the blue. I hadn't downloaded anything recently, it just started doing it! I'm not really very good with computers so all I've done so far is take the advice of some people on other compuer help sites, I've started it up in Safe Mode and that made no difference, I turned off the automatic restart on My Computer and instead of getting the blue screen with hopefully an error code, all I got was a frozen black screen, occasionally with a low-resolution cursor stuck on it and with the computer, which was previously making a great deal of noise go totally silent. So I had to restart the computer again myself. Oh, and also I've tried doing a System Restore to a few days before it started but before the Restore can finish it the computer restarts again, it gives me so little time to do anything! Please help me! What the hell is wrong with it?!

bldycomputer, just a SWAG, but worth a try. Sounds to me like a worm/trojan at work. Be aware that a virus and a Trojan are similar, but not the same. Many times, an AV detects one it can't clean, other times, it gets missed entirely. If you need to clean one, Superantispyware can do the job and you can get it free @: http://www.superantispyware.com/ among other places. They have a Vista compatible version if needed. If it turns out that you need to use it, be sure to update prior to running and disable 'restore' (restart after cleaning) so it doesn't get put back. They just released a new update recently and it changes all the time. Things are in a constant state of flux. The restore thing is critical. May not be your deal at all, but won't hurt anything to try. HTH. Ed in Texas.

Hi If you have not installed or made any major changes recently, which you said you have not then I will suggest you do some cleaning of your system. You better clean the RAM and RAM slots, PCI slots and the processor assembly. hope this helps......

sounds very much like your systm is overheating either your psu power supply unit or your processor look to see if there is a build up odust in the fins on both if not then try replacing the psu

hey boy you check the smps he is working properly or not means, if he is fan speed is faster than other pc's that's the smps problem & then he also restart after 2 minuts. second is cpu problem.he is not set properly.
