Need help please :-(

Reinstalled Win XP last night since I can't use Coretemp/ATI tool in Vista.Ever since then I've been getting random reboots and BSOD when ever I try to load Coretemp
The only thing I've done that might have caused this is take out 2 of the 4 ram modules to see what my Q6600 can do.

I've tryed all sorts
Is it possible its just a bad install of windows?

My Q6600 primed fine @ 3.6GHz but I ran it out stock just incase.
I've just started running memtest which has 2 error so far @ 18%
Will try my other 2 sticks off ram after the test.
Ram is Crucial Ballistix 2GB (2x1GB) DDR2 PC2-5300C3(x4)
