Serious Error Recovery Message - Random Shutdown Problem

Well, the computer didn't blow up, but I think it came close.  Lately, we've been having a random shutdown problem, and we'd hoped we'd solved it with a new GeForce 6600GT video card and downloaded the new drivers ... a whole 24 hours go by without a random shutdown!  Huzzah!  Then, last night ... you guessed it.  Random shutdown.  Then, today, before we had a chance to do anything ... random shutdown.  After the reboot, we get THIS message from Computer Hell:

"Your system has recovered from a serious error."

Here are the *THIRTEEN* error codes that I copied from the pop-up error notifications.

PLEASE, for the love of dogs, can someone make sense of this mess before we build a sacrificial altar in the backyard for the computer?

Oh, and could I go way beyond all normal hopes of us ignorant dorks who beg for help .... and ask that whoever answers *NOT* tell me how stupid I am?  I know how stupid I am.  Trust me on this.

Thank you!  Bless you!
