PC suddenly acting fishy

BleepingComputer.com,

My desktop computer has suddenly started acting very weird. Firefox is crashing nonstop, crash after crash. The computer will suddenly shut itself off and restart to a "system recovered from a serious error" error. I am getting all sorts of error reports. I have no idea what any of what I am experiencing means. I am far from a computer guru.

Please help if you can. I appreciate any help and reponses I may receive.

Thank you.
