G31-M7 TE with intel quad 8200

I'm having some pretty major problems with my brand new pc. I can't play any games for more than a few minutes without getting the nvlddmkm.sys BSOD. I've been through all the fixes on the net, updated all drivers and done everything I can think off. I was on the biostar website when I looked at the processor compatability list for my motherboard and noticed that the intel quad 8200 wasn't on it. The only quad core's on the list where - X6800, Q9400, Q9300 and Q8300. Does this mean that this incompatablity could be causing the problem?
thanks
