I have an A7V333 with an Athlon XP 2400+, and one stick of generic 512Meg
PC2700 RAM. The computer was running normally till the other night, when I
powered it up, and no video. The Post Reporter went into an endless loop of
"System failed Memory Test." I unplugged the power supply, shorted the CLR
CMOS pins for 30 seconds, and tried it again. The system has only one card,
ATI 7500 Radeon AGP, and it's seated properly. This time, the Post
Reporter went into an endless loop of "System failed CPU test." The voltage
on the battery was 3.02 volts. I replaced the battery with a brand new one,
which read 3.22 volts, but it made no difference.
I took it too a friend's house, and we tried his memory and CPU from a
working machine, and my system responded with the "failed CPU test" message.
My memory and CPU woke right up, and worked fine in his Abit NF7-S board.
We also tried my power supply on his board, and again, his board booted
right up, and the hardware monitor showed all the voltages as normal.

Is my motherboard toasted? Or is there something else that can be done
here?

Try clearing the CMOS again plus changing the JEN jumper. If you are
changing it to the jumper mode make sure you have the correct frequency
settings. It it boots ok after that you can change back.

Sounds like it. If every jumper is set at default/factory for the CPU and
the bios has been reset and it still won't post, I'd say it's toast.
 
I tried every combination of jumper and DIP switch setting that the hardware
would recognize. It kept coming up with the same two errors, but mostly the
"CPU Failed" one.
Would there be any use in trying a new BIOS chip? Is it possible the BIOS
chip is what's gone, or is it more likely a CPU/memory buss controller that
has died?

Try putting the ram in a different slot and reseating all the
connectors. Since you removed and reinstalled some things it's a good
idea to make sure they were reconnected to proper location. Also be sure
to clear the CMOS each time.

I wouldn't waste my money on that. Like someone else said try reseating ram
etc but sounds like you have a clue about what you're doing and have
probably already tried that... Had any thunderstorms lately? Seems them
take out a MB like that.
