Hey guys. I'm feeling a little helpless, thought I'd ask the opinion of others.
I just built a new system (don't think specs should matter in solving this issue, but I'll put them at the end just in case). I recently installed MW3 via Steam. The computer0 crashes - at the same point in Single player or 5-10 minutes into multiplayer. There's no blue screen. The computer just restarts. It's almost as if the plug is being pulled.
Now, for trying to provide information to eliminate some probable causes:
Other games: I've played BF3 for several hours at a time on this rig, also Crysis 2, MoH, among others. No issues. CPU/GPU temperature: Not an issue. MW3 seems to be less demanding than the previously mentioned games. I track and log them. CPU maxes at 55C, GPU at 65C (i5-2500K and GTX570) Power Supply: 700W. Admit it's on the low end, however, more than 100W above recommended PSU from graphics card manufacturer. Plus, I don't have any issues with other, more computationally intensive games. Drivers: All up to date. Stress Tests: I've run a memory stress test using all available RAM for two hours. Also Prime95. Then both at same time. No issues. Overclocking: I don't do it.
Any thoughts? Anyone else experience this on any game? Not many hits on the Google for this occurring for MW3. I admit, the symptom points at a hardware issue, however, the performance for other more intensive games and stress tests really appears to invalidate that.
Windows 7 Professional x64
Gigabyte GTX 570 (factory OC version)
Thermaltalk 700W PSU (56A combined +12V over 4 rails)
MSI Z68A-GD65 (G3) Mobo
2x4GB G.Skill 1600 RAM
Here are a couple of things I did.
1) Reinstall game. This also appeared to reinstall DirextX.
2) In NVidia control pannel, I set 3D settings to Application Controlled. They were set to Advanced.
3) I unchecked "automatically restart" per the above, expecting a crash.
I haven't played much yet, as I just got home from work and haven't eaten dinner, but I at least got past the one place the game always decided to crash. Will report back if problem persists, or if it's fixed. I know there are others out there with same issues.
Thanks guys for your input. Even though I said power supply was fine, it was not. I'm guessing that because its +12V was split over four rails, one of the rails was overloaded when the system drew too much power. I bought a new single rail PSU, with similar wattage (750W for new vs. 700W for old) and the problem went away. Strange, MW3, Black Ops, etc overdrew system power when BF3 did not. This puzzles me quite a bit.
