1. Check discussion boards for those games about the issue.
2. Ask the machine's maker for an install plan for the OS and drivers.
3. Disable the sound card for a test run to see the video works. Can help you determine if this is a driver problem.
I find many don't know the three areas to check so I've put them here so you know where I go.
Okay so this problem has stumped me along with a couple other people. My problem is that the audio and visuals will cut off while my computer is under load (such as when playing a high end game or when two large armies clash in Starcraft II). The thing is that the computer still seems to be running when the monitor and audio cut. I've checked the temperatures of the GPU and CPU and I know it's neither of those as both have run at around 60 C max. I'm also quite sure it's not the power supply as I've swapped it out 3 times, 2 being 750 watts and 1 being an 850 watt. It also doesn't seem to be the video card as I've tried 2 different video cards. RAM also doesn't seem to be the problem as, like the other things, I've swapped out one for another (I'm running with 8GBs). I've also checked my wall outlet's voltage to make sure that it is 120 just in case (it was indeed 120). I am using Windows 7 Home Premium x64. Anyway if anyone could help me with this problem, that would be golden. Thanks in advance. These are the parts I used in my build including links (including the parts I swapped out):
