Crashing games

[fenris1011]

Hello all.

I recently bought a Geforce 8400GS. Installed and everything works fine except games...

First tried starting WoW, the blue screen pops with a massive message but I cannot read it because the computer reboots itself, fast.

Tried with a different game, Call of Juarez, and the same happened.

Any ideas? Installed latest drivers and cleaned of old ones.

Thanks.

Okay...rebooted for 5th time and everything works.

But WoW is lagging worse than my old integrated geforce 4mx....

It isn't the internet.
