After 2 seconds of play,either offline or online,my computer freezes and I have to reset manually.
Any clues?
I have updated my radeon card's drivers just now,and it still occurs.
AMD Sempron 2800+
512+512 DDR RAM
300+80HDD
Gigabyte GA-7VT600(-L)
Ati Radeon 9600XT

Both of my drives are defragmented.

I have uninstalled and reinstalled it ,and I tried playing with full screen resolution but the problem is there.

Please help:(

How well ventilated is your computer? If it runs fine for two seconds and then completely siezes up, it sounds like it could be overheating.

I have three fans on my pc case,one extra cooler in my VGA and a cooling system installed on my CPU.I tried ''toast'' program and it does not freeze until 57 celcius.When playing W4 it reaches 53 celcius so I don't think this is the problem..
