Question Vintage Computer Not Booting - Gateway Performance 650 TB3

[BeigeBandit]

I thought a fun Christmas project would be the resurrection of the the old family computer, a ‘Gateway Performance AS 650 tb3’.

To give some back story, about a year ago I dusted off the internal components, when I put the computer back together it booted fine but crashed a few seconds latter. Now all I get when I turn it on are beeps codes.

The code specifically states that ‘the video card is faulty or not installed, or an external ROM module does not properly checksum to zero’.

So I have a few questions:
1) Given the age of this machine how do I know what replacement GPU’s are compatible?
2) If it is the ROM module that’s fizzled, how do fix that?
3) I’ve been unable to find a PDF manual for the computer anywhere on the internet, was hoping someone could help me with that?

~Thanks in advance for any help I get on this.

Start with a new bios bat.....cheap test.

Didn’t work I’m afraid.

Reseat all plugs/cables/ram/add on cards.

That didn’t work. I suspect it is the GPU that is broken, but I don’t have a spare AGP card to test this out with. Is there anyway to boot the computer into the bios, or is it impossible for these old computers without a graphics card?

Depends on if the cpu or the mobo has an igp.
Remove the gpu and plug the monitor into the mobo....test.
