I only encounter this problem when i am playing a game.. usually it is when the game just starts up, after a save, or loading a new level/area. I am usually able to alt tab and quit the program. power supply is fine and there is no dust, also it is not over heating I have screenshots of what happens during a freeze but I cannot post them at the moment (this is my first post) Here are my specs OS Name Microsoft Windows XP Home Edition Version 5.1.2600 Service Pack 3 Build 2600 OS Manufacturer Microsoft Corporation System Name REIDFAY-9532C40 System Manufacturer Gigabyte Technology Co., Ltd.
