GeForce3 Ti-500DDR 4x AGP Video Card with TV-Out(Blanks screen at boot

Question

I just bought a Ti500 from a online store.
I tried reinserting the card into the AGP slot many times.
I've removed my original old PCI card(had to put it back in later though to USE the computer). When you turn on the computer it performs the POST and then runs the boot loader. I had some extra stuff
to do in the boot loader(mine has a command line) so I couldn't
get the OS booted before the card started acting up.
First it will garble the video output(text will be messed up along
with graphical artifacts all over). Then the screen goes black after
a second. It does this everytime after a short amount of time
after the computer power on(No matter what is running, it has done
it in the BIOS setup). Is there something wrong with my system
or is the card defective? Also, how can I tell if this is a real
Ti500 because MSI doesn't list the card on their site.
My system:
400MHz Celeron
128MB RAM
I've read something about AGP versions supported by the motherboard..
I have no idea who made my motherboard so I don't know its AGP
version. The BIOS copyright displayed is to 1998. The site
I bought the card said nothing about AGP version requirements though.
(I have had a Geforce2 MX AGP in this machine before and it worked)
How do I check the AGP version  in linux?

Answer 1

By power supply on the low side, do you mean that my system
power supply is too low for the card to function properly?
So in order for the card to work, I will not only have to purchase
a new motherboard and processor, but also a new power supply(and case)?
I figured out how to get the AGP version information:

(Note: I put the Voodoo 3 back in to use the computer).
Also Power supply info:

Is there anywhere I could sell/trade my no longer needed hardware(extra
drives and cards) that'd I get a reasonable offer to put towards a new
motherboard/processor?
