my computer always shuts off between 5-20 minutes of ingame on mw2 that i recently downloaded. the graphics card goes crazy like 5 minutes into playing it. thats when it sounds like someone turing on and off a powerdrill as fas as they can. creepin me out here.
heres my specs:
model: DELL studio XPS 435mt.
GPU: ATI radeon HD 4850
CPU: intel i7 920 (2.66 GHZ)
RAM:i think its 4gb but might be 6gb. havent relpaced any parts sice bought
Motherboard: DELL r849j
OS: windows vista (64-bit)
hard drive: 500 GB
when i turn it back on works perfectly until i play the game again.
I'm start by guessing that you're having temperature problems and suggest downloading HWMonitor and running it while you play MW2 in a non full screen so you can see how hot your stuff is getting. After doing that, comeback and tell us. If you start to go over 80C go ahead and stop and comeback and tell us that.
Have you ran your computer with the case open to see if that brings your temp down? Obvioulsly that not a permanaent solution, but if your temps become reasonable then we know we just need to get some airflow into your case with some more fans or bigger fans.
OCCT will load your system and record temps w/o a need for a 2nd and 3rd program to be running .... it also graphs the results which you can then look at later so you don't have to sit there and watch.
Try blowing some compressed air into the fan shroud on the card (pressurized air sold at puter stores)
Try taking off side window and using a desk fan to blow air into case to rule out or confirm case cooling as the problem.
