Hi,

After swapping a Athlon X2 4600(dualcore) for a Phenom 1 9750(quadcore, 95w) in my PC(Asrock Alivesata2-glan) it has suddenly started to crash, especially when streaming video content, but also on a few other occasions. Sometimes it just hangs, and sometimes the screen goes black(doesn't reboot). Even though the CPU isn't listed on the official support page, I've managed to get a beta BIOS(2.61a) from Asrock. According to them my CPU is tested with the beta and is supposed to work. 
Both device and task manager shows 4 cores. SisoftSandra reports a temperature of 30 celsius. I've updated the videocard drivers as well as flash. When I booted up the machine for the first time after the swap XP(SP3) was installing some new drivers(PC-host?).  Even before swapping CPUs a had strange problem. Everytime before starting up the PC I have to disconnect and reconnect the keyboard for it to be recognised. Re-installing the (keyboard-)drivers hasn't solved this problem.
Might a clean XP installation solve the problem?

Please help. 

I didn't find the right solution from the Internet.
