Ok.. I have problems that are realy testing my nervs.. My comp. is not very old only few months. Now a week ago I started expiriencing very weird game crashes where my computer restarts by him self. At first I thought it's a temperature problem but bios reports 30c never above that. It doesn't crash on every game. Warcraft runs very well, so does new need for speed and baldurs gate but when I start oblivion or sin episodes or neverwinter nights 2 it gets wierd. I doesn't restart as soon as start the game. It let's my go to new game, plays the first animation, the game starts, I move around a bit and then zap! the comp. restarts. One thing also bugs me I played all of these games a month ago with no problems and now things are messed up. all of my drivers are updated I have winXP with service pack2 I have scaned my harddrive for viruses I tried reinstaling the games I also defragmented my harddrive but the problems are still there. and I ran directX diagnostic tool and it reported no problems me: Intel pentium 4 3.00GHz 1 gb of ram Maxtor hdd Nvidia geforce 6200 Sound blaster live 24-bit samsung monitor I would appriciate any help and sorry for my bad english grammar..
