Screen Freezes During Gameplay

sys specs:

ASRock 939 Dual Sata MOBO

Hello all. Recently I upgraded my budget gaming rig from a single core cpu (AMD Athlon 64 4000) to a dual core (AMD Athlon 64 x2 4400). Before I did this upgrade I had no problems at all playing Aion, Secondlife and COD2. But after the upgrade, I get anywhere between 10-45 mins of game play, then my screen freezes and I have to hit the reset button to restart my PC. At first I thought it was my graphics card over heating but I ruled that out by monitoring it and it only runs at 49c-52c under full load. So I reinstalled all the drivers and rebooted and tried to play again..but with the same outcome.

I also ran memtest on my RAM and monitored my core temps (only 33c-40c under full load) on both cores. So I'm really stumped as what the problem could be. I've googled until my eyes bled and still haven't found a solution. I'm sure I have enough power to run my system because the wattage on the previous cpu and the new one only varied by .2v. Any help or insight to what the problem could be, would be greatly appreciated. Thanks in advance.

Well...I just reinstalled my old CPU and everything is back to normal. Still stumped as to why that happened.

Do you have the newest BIOS for that board?

Crap..thats the one thing I didn't think of. Lemme go google it.

Okay..I checked the bios version and the one I have for this board is P2.30, which is the latest released bios. Although they have 1.30 that is supposed to support the exact processor that I have, but its a really old bios. Should I attempt to use the older bios? And if I do will it mess up other parts of my system?

I think Imma just give up on this issue an just auction the CPU on ebay so I can at least get some of the money back I spent. Thanks for your responses.
