PC turning on and off by its self??!!

FistFullaSteel · 08-10-2007, 12:55 AM

My pc has been doing this thing where it turns on and off all by it's self.
Like it has done this about 4 to 5 times before but now it wont stay on
at all. It just turns on and off on and off at no discriminate length of time.
It just turns off and on off and on till i pull the power my Power button doesnt matter, and on that matter my power button has well become WAY more senseitve...odd. But idk whats wrong my diognostic lights go crazy but they land on 3-4 out of 1234 diaognostic lights. Now my manual suggests a few options to test this "possible memory problem" and I have put known working ram in it but to no good note. So i got a feeling its like a virus maybe or PSU problem? I'm feinding for my BF2 so some one PLZ HELP! i dont know what to do anymore.

it just worked again today for about 25mins and then actually shutdown nicely kicking me from game to windows and then shuttingdown and going back to turining on and off on and off lol.

what are your voltages and tempreture readings
have you upgraded anything in the computer the psu looks a little on the light side for that system

Do i need a program to check those?
i have to say all ive done is put a aftermarket fan
inside by GPU which is working. im typing this on the
busted pc! but it could die at any time
more reasons leaning to virus?

You could have a look in BIOS or use SensorsView (link in my signature) to monitor the voltages and temperatures.

well its down now again itll only work for about 15 mins and thats at about 2 times per day its odd

Have a look at the voltages and temperatures.

well as a temp fix i found one that is the same as factory exactly, and only 40.00 $
how i know that one would work?

**Deleted090308** · 08-12-2007, 10:22 PM

What's the brand/model?
How did you confirm it's a bad PSU?
What programs have you used to scan your computer for viruses/spyware?

i had a guy hook a PSU tester to it. It lit up all red and was clearly in a fault of some kind.
