new install of windows 7, currently running windows 7 professional 32 bit, nvidia geforce 8400gs with drivers from nvidia. sapphire technologies mb, amd athalon x2 4450e cpu. checked with fanspeed software the system is running within normal temperatures( currently half the tower is open).
the system locks up at random - on the home screen with nothing open, when i'm in firefox when reading, when i'm updating. at the moment i'm playing a dvd in wmp in the backround and so far its the only time it hasn't locked up.
