Poor computer

I had a blue screen of death today. I didn't think XP did blue screens of death, that is sooo Windows 98.

I have momentarily blamed Windows Live Messenger, which I think is the only programme I installed recently. It lasted a while before the problems began, but it seems a likely candidate to blame. So I've closed that down and prevented it from starting itself up again. Same with Skype.

For the geeks:

KERNEL_DATA_INPAGE_ERROR
****STOP: 0X0000007A (oXC02016E4, 0XC000000E, 0x805B709C, ...)

I couldn't write down the last one before the computer shut itself down. Oh, it did a disk check thing and froze after giving me the results.

Please... does anyone have any ideas how to cure my computer?
