Blue Screen of Death

I turned on my computer this morning and started having problems. First I got BSoD with error message Driver_IRQL_Not_Less_or_Equal 0x000000D1 and it rebooted. A checkdsk came up so I figured OK no problem. Then it restarts and I get BSoD again with error code 0x0000008E and another restart error 0x0000007F. I've tried getting into safe mode all it does is reboot asking which mood I want to boot in. I've tried doing a repair and the Blue screen just come up in the middle of windows checking the system. I'm using windows xp. Any help would be appreciated. Thank you
