So, is this a power supply issue?

My system instantly restarts during long sessions (~1+hrs) of company of heroes. I've never had it restart in any other situation, only coh. I'm assuming this i because coh is highly processor/video card intensive.

My system is as follows:

E6600 @ 3.0GHz - +0.0875v over stock
DFI Infinity P965 - all voltages stock except for processor.
eVGA 8800 GTS 320mb
4GB Crucial Ballistix PC2-1000 (4 sticks of 1024mb)
Antec Truepower 850w
All components (cpu, nb, video card) are water cooled.


Now, this system WAS rock solid for a long period at these exact settings, then suddenly the restarts happened just after I upgraded nvidia drivers - I believe this to be a coincidence as I've swapped out all different kinds since.

When I bump my voltages up on my peripherals, the reboot becomes almost instant when I'm in coh, so more voltages = worse.

I just ran orthos for 20 minutes (yes I know that's not long enough but I'm pretty certain 100% flogging doesn't occur in COH) and never had any hiccup. My temperatures are all very low, my video card peaks at 49C, my processor @ 44C, NB @ 55C so I don't think any of that is an issue. I have put fans directly on the mobo and peripherals just trying to troubleshoot but it has no effect. My PSU only runs my mobo/video card, my case has only 2 fans for the radiator and that's it, I have an extremely low power pull on my psu, and 850W should be ridiculous overkill.

thoughts? I really need some help here because I'm seriously about to hang myself.
 
I wouldn't think this is a PSU issue unless of course, the PSU has actually gone bad, which is a possibility. Your PSU is rated nearly 400 watts over what I'm running in addition I've got a slightly higher load, so in all reality, it should be fine.

The only thing I can think of is maybe you need to bump up the voltage on your northbridge. Considering you're running 4 sticks of ram and you're at 333MHz on a P965 chipset, it is entirely possible that it needs more juice. Why the problem is only happening now I don't have an explanation for, but this is where I'd start personally.
 
I'm experiencing something like this, too.

E8400 (3.0 --> 3.6)
Gigabyte 8800GT (stock 700 OC'ed core)
Ultra 600W PS (came stock with Ultra MicroFly MX6 case)
Gigabyte GA-G33M-DS2R mATX
RAM - currently Crucial Ballistix PC6400 (DDR2 800) though I've tried similar Corsair and Mushkin

While gaming, I am getting a screen freeze for about 3 seconds then an automatic reboot. Doesn't matter if I've been playing for 5 minutes or a couple of hours. It is entirely random.

The PS is rated 35A on the 12V rail which should be plenty. Though stock PS's are notoriously overrated, I am skeptical it is a PS problem. At first I thought it was a crap vid card but I installed a new Asus 9600 GT (uses less power) and had the same problem.

I can do normal activity all day long without a crash. But when I start gaming, no tellin' how long I got before it reboots. The kicker here is the only time I've had a reboot outside of gaming is from watching videos at a newspaper website. Little videos like this are just not very system demanding so I'm stumped....

Right now, the only thing I've eliminated from troubleshooting is the video card because I've had the same thing happen on two different makes and models (of video card). Motherboard, PS and even the RAM are still suspects....
 
mine was the 4x1024 sticks of ram, no matter the northbridge or ram voltage, I just couldn't keep it stable. This is normal with the P965 chipsets though, 4 dims on an overclocked system always causes problems. I'm a game designer so I spend most of my time in 3d studio max, and I need 8GB of ram, so I'm going to put it up for sale. Having to go to 2x2048 sticks, check the for sale forum if you're interested.
 
Not really surprising. FWIW, I'm running 4x2GB sticks on my P35 board, overclocked with out any problems. I upped the northbridge voltage by .1 just for some added headroom. It was actually stable at default voltages.
 
If you know anything about cruical ballistix ram you know they go bad. blue screens and/or shutdowns. change out the ram and give it a shot. i doubt it is the PSU.

you should probably read follow up posts.

Well, as mentioned, I tried similar Corsair and Miushkin. No help - same problem. The Mushkin actually went bad on this board but it was old stuff. Since this particular RAM was no longer produced, Mushkin was able to RMA it for something newer but with less spec (old = DDR2 1000, new = DDR2 800). Since I sent back 3 x 1GB sticks, they did give me an extra stick (4 x 1GB) of the new stuff. BTW, I've never used more than 2 x 1GB at one time. I'm still using XP so 2GB is plenty....
