computer shutting down I have a weird problem with my computer it works fine when I‘m online or running basic programs. When I start to play games the computer will work for about 5 minutes then make a buzzing sound then shut off. I have downloaded a program to see the CPU temperature and it don’t get above 74 degrees Fahrenheit. It’s a custom built pc that a friend of mine did that has a 64 processor an ati video card I think a 9800 and around a gig of ram. The guy who built it is in iraq right now and I have no idea what the problem could be.
