Kernel_Data_Inpage_Error?

I got BSOD on my XP pro today, that's the first time it's happened....I just did a fresh install two days ago, things have been better so far, less problems gaming but I got this kernel data inpage error on the BSOD....And basically i'm just wondering if any of you know causes/solutions of this type of error...thx.

What did it say exactly? did it have anything like memory locations or register locations?
