Hello. When I insert my PC game and try to play it, the game will run normally for about 10-20 seconds and then the entire computer will enter a "hibernation" mode in which only a black screen can be seen. No blue screen of death or anything. Also, when it enters this black screen a light "clicking" sound can be heard from the hard drive. I recently had my hard drive formatted because the old one was bad, and had my entire C drive transferred to the new hard drive. I have checked my directX, and it is up to date (9.0c), and I have gone to "Run" and typed in "dxdiag" and have run all tests therein. Everything seems to be working properly, except this game won't run for more than 20 seconds. I hear that playing a PC game pushes CPU performance to 100%, but I don't think this would be a problem. Can anyone help? Thank you.
