I managed to get my hands on a near perfect condition AOpen AX34 based system with an AOpen Case (Idk what the model is) and an AOpen 250 Watt PSU (FSP250-60GTA).
After a few upgrades it now has a Pentium 3 933MHZ (OC'ed to ~1.06GHz), 786MB of SDRAM installed, and WinME (don't laugh it works well for me) on a 80GB drive plus some dvd drives, floppy drive, and a zip drive.
It came with some SIS agp card wich I threw into my SIS box immediately in favor for my most powerful Nvidia AGP card I own, which is the GeForce FX 5900XT (Gigabyte GV-N59X128D)
Then the system refused to boot.
At first I though it was the FX 5900XT finally breaking down, so I put it back in another Pent 3 system to test, and it booted just fine. Then I tested it in 5 other PCs of vairying specs and wattages and they all booted up fine as well.
So I though maybe the PSU or Mobo can't handle the wattage or something, so I put the only other molex powered AGP card I own which is an Ati (Refrence) Radeon 9800 Pro (128MB) in to test and that booted too.
Then I thought that it just doesn't like Nvidia cards, so I put 5 different Nvidia (AGP powered) model cards like my old TNT 2 and Geforce 2 MX in and the system booted just fine.
So at this point the only thing I can think of is the fact that the AX34 mobo or the FX 5900XT has a problem booting together.
If anyone has any ideas to fix this or can suggest a similar Nvidia card to replace it with let me know.
