Ok here is my problem, when I try to play a game the game will stop responding meaning that I have to restart my computer, this has happend in all the games I have played so far which are Age of Empires III, Battlefield 2 and LOTR - War of the ring. It does not give any errors it just stops responding and CTRL + ALT + DEL does not work, the only thing that works is to restart the computer. So how can I resolve this problem? Here is my spec: Mainboard: ASRock K7NF2-RAID CPU: AMD Athlon XP 3200+ Memory: 1,0GB DDR SDRAM (2 512mb bricks) Graphic Card: Sapphire Radeon 9550 256mb HDD: 40GB Western Digital S-ATA OS: Windows XP Home Edition SP2 OEM Licence. Need help please!
