PC keeps on restarting

Before, my problem was too much Blue Screen occurring on my PC. I replaced my A-Data RAM Sticks and bought the RipJaws X Sticks, and I haven't experienced a single blue screen so far. Now my problem is my PC keeps on restarting for an unknown reason. I know it's not my RAM Sticks anymore because I haven't had any blue screens lately and when I check the memory dumps, there are none unlike before when I was experiencing the blue screen.

My PC will suddenly restart out of nowhere (when I'm playing, watching a movie or a tv show or browsing the net). I don't know which part is causing the problem. How can I diagnose it?

I'm thinking it's my power supply because the power flicks for a second that's why my PC restart but if I thought of it again and, if it's really the power supply then my PC should not restart itself. I mean if the power was gone for 1 second, then the PC should turn off after that one second power flick, not restart itself. Right?


Here are my computer specs:


Processor: Intel Core i7 860 @ 2.80 Ghz
Motherboard: Asus P7P55D LE
Video Card: ECS GeForce GTS 250
RAM: 2 * 4 GB G.Skill RipjawsX DDR3 1600Mhz (Single Channel Configuration and I don't think it's running at 1600 MHz. I haven't overclocked it.)
Power Supply: 500 W. I don't know the brand because my dad bought this CPU from Greece built already.
Hard Drive: 1 x 1 TB Seagate

Has this computer ever worked or has it always had problems. Do you or someone you know have an extra PSU you can use to test. It could be the PSU or maybe the motherboard but I would troubleshoot the PSU first then go from there.

Well if it's been running okay otherwise, I'd assume it's the power supply. As for it automatically restarting, I think there might be a BIOS setting for that. Don't quote me on it though. However, if it's Windows causing the restart, there is a setting for disabling automatic restart on failure (you said you had RAM BSOD issues so I assume you're familiar with it but if not..) http://pcsupport.about.com/od/windows7/ht/automatic-res...

it could be the power supply or it could be that the outlet in your house has a lose wire or there to many iteam on that breaker.
to test your power supply download hardware monitor and prime95. open up the monitor and watch the 12v 3.3v and 5v rails when you up your pc in the stress test. if the power supply is bad it will drop and you can see it.

Note: My dad bought this last February 2010.


@Rds: When it was new, it was working fine. After a few months, the restart problem started.

Could it really be the power supply? Let me just clear this up. If the power was gone even for a second, it should stay off right? Not restart itself. Because the power was gone and until I press the power button again, it should not turn on.

@smorizio: I tried what you told me but it only dropped by a few. Only 0.03 or 0.02. Not a huge drop. I used the In-place Large FFTs.

PSU problems can do just about anything. I've seen PSU problems do everything from causing boot problems to causing a BSoD. In IT there are two types of failures due to PSU problems. The first is catasrophic failure when the computer just won't start because the power supply is blown. The other is intermittent failure and when this happens the PSU does start because the PSU isn't compleatly dead BUT it's on it's way out and as I said it can cause anything from random retarts to BSoD.
