CoD: MW3 Crashing

igorm · 22 Feb 2013 at 12:56

Didn't know where to start the thread, so I did it here.

I have upgraded my PC (GPU and Ram) few days ago and after that got MW3 game. The problem is: after few hours of playing MW3 (maybe even less) my PC crashes - monitor switches off, sound is stuck on loop and nothing is happening. I have to restart my PC by myself. Event log doesnt show the reason for the crash (maybe because there was no actual crash, since I manually restart it), only after restart it says that PC wasn't switched off correctly.

I thought it might be overheating of my new GPU - nope! Temperature didnt go past 43 degrees. Did both CPU and GPU stress tests at the same time - CPU temp didnt go above 50 and GPU didnt go past 60-65... I have no idea where to look for. Does anyone encountered that before or know any tests that I can do to figure out why is it happening?

I had a similar thing happen with Black Ops when that 1st came out. solved it by lowering the core and memory clock speeds on my gfx card a little using the MSI overdrive tool for the MSI R6950 Twin Frozr III Power Edition/OC.

Cant say for certain if it will work but it solved my issue.

I didnt even overclock my GPU yet, it is as it was overclocked by gigabyte.

and to what values should I do it (it is Gigabyte HD 7850 by the way). Atm I am at Core: 975MHz and Mem: 1200Mhz. And should I do something else apart from lowering the values in the MSI Afterburner?

Ok, thanks man. Will try and do that.

But is it problems in GPU or the game?

yep, all of them seems to be running on IW engine. Anyhow, will underclock my GPU and will give it a go...

But I dont undestand, my GPU usage is not even that high during the game, definatly not enough to make it unstable and crash...

2 hours into the game and still no sign of crash (usually happened within first hour, hour and a half), It seems that it did indeed help, but I dont understand why though...

P.S. DisrupTor75, thanks again for the help.
