Booting Woes

[georgencopy]

After a trouble-free year of happy computer usage, I updated my anti-virus program (which has been updated regularly and worked fine for two years) and shut down.
Two days later I restarted and never made it past the POST screen.
Windows XP Home SP2 would not boot in safe or any other mode, including "last know good configuration."
It would not boot from a rescue CD or a rescue floppy.
I manually reset the CMOS and got back a "keyboard lock error."
I found the pins to disable keyboard lock in my mobo manual, but my Antec case has no keyboard lock feature--at least none that I can find--and no cable/wire that goes to case (they're all nicely marked.)
I also get a CMOS checksum error.
And that's all the further I've got.
Help please.

Sounds like your BIOS got corrupted. Would not boot from rescue cd or floppy and CMOS checksum error.
You could try to flash BIOS but not if you can not boot from a floppy.
Is this under warranty, perchance?

And the sign says "You got to have a membership card to get inside" Huh

They say the limited warranty is good for three years.
I guess I'll see just how "limited" it is.

I would say that is covered...
