Exclamation Computer Hard Shutdown! NEED HELP!

ok so heres whats going on, ever since I got my new Quad Core my computer likes to do the hard shutdown on me where it shuts down like it lost power then started up again, Such as when im playing Crysis and once after it did a shutdown on me when I was in the bios checking the temps. Anyway heres what I have done and know. I know the CPU is making good contact with the heat sink because its temps are in the normal zone. No Dust in the system and only started happening after going to the Quad Core. Also it seems to only happen on Crysis or when something Huge is going on, Never happened when I played Team For2 for a few hours.

Now the question is that maybe my power supply is not cutting it anymore. I have Ultra 500w Power supply
http://www.ultraproducts.com/product...&productID=157

Maybe its not giving me the juice anymore with the Quad and when its using all 4 cores its just running out of juice, since I also have 3 hard drivers and 2 CD's on the system.

But yeah any advice to see Thank you for the help!

Yea, sounds like a PSU issue to me. 34A +12v rail is a bit weak these days, especially with a G80. Afterall, you are running quad, 3 hard drives, 8800, soundcard, and 4GB so under load you might be pushing it's limits. Also it could be that your main power connector isn't securely in place or one of the wires has been damaged, I had that happen a couple years ago and was experiencing the same issue. So check that first, but I'm pretty sure you don't have enough power. Also, are you really running a Q6600 on an 865 chipset? I didn't even know that was possible... it also be your problem, possibly if it doesn't have a 24 pin main connector.

From the looks of it, your PSU should be fine. 500w is still cutting it close though, so you won't have any headroom for overclocking. So just get a new !!quality!! psu and see if that fixes it. A 500w psu should be enough for your comp, but it might just be that it's getting old and can't keep up with the rest of your system(capacitors getting old etc.).

You can probably get a good OCZ for that price.

Mine was around $120 about a year and a half ago and its been perfect for me.

EDIT: Hear you go. http://www.newegg.com/Product/Produc...82E16817341002

$129 with free shipping, $94 after mail in rebate. Can't beat that.

Also, I think the power supplies are still made by FSP\Fortron and they make some really reliable stuff, so I trust the quality of these units.

Yeah, if your PSU is old it might not do 500W anymore due to capacitor aging.

nice choice, corsair always chooses quality OEMs for their PSUs.

I had PSU problems like that once, I just plugged the computer in a lone wall socket instead of my surge protector and no more shutdowns. I also tore my aorta once while fishing for mudpuppies on the planet Sausagecon.
