BSOD Kernel_data_inpage_error

[apdrummer]

can anyone let me know what this error is, I looked it up, but I didn't get a good explanation. I'd like to know if it is a hardware, driver, OS, or other issue. as well as suggestions on how to fix it. I've only just recieved this BSOD a couple of minutes ago on my very new computer (specs in sig) running windows XP.

I recieved this message while playing oblivion. Temps are normal, system/cpu idle at ~42C load into mid 50's. 8800 GTS idle at ~61C don't know load, probably around 70C. XP is upto date, and I had updated my graphics drivers just earlier today. I ran oblivion probably an hour before the BSOD came up.

I'm really worried my new rig is screwed up, It booted to the log in screen normally but I just turned it off. Any help would be much, much appreciated.
P.S. The MS website said this could be a hardware or software issue so I just put it here.
