i having a problem here, my pc cannot restart when i open any program or software. But if i open the pc and open nothing on start up, just open and restart it. then it was no problem to restart. But if i open up some program like game or microsoft office, then it cant be restart. i try to uninstall the game and some software, even i reformat also like that. So i decided to reflash my bios, after reflash it go normally... no problem at all. But i really not sure it a software, firmware or hardware problem... Can any pro can tell me what the problem is?? i really noob on this... my pc mobo is asus p5k pro, c2d e8200, 2gb kingston value ram, and a 8800GTS gc. thank you.
