Recentlty, i got a PC with an Abit AI7 which i mentioned in one of my threads (Worth getting scrap PCs with an Abit AI7 and Intel D865PERL?), but i found that the board have an issue, it can't POST when a videocard is installed on the AGP slot, there no presence of blown/bad caps, i already tried multiple CPUs (Northwoods, Prescotts..) and RAM, also other PSUs and reseting the CMOS, but still nothing

The results are:

No RAM, no videocard, no POST, RAM error beeps

No RAM, PCI videocard, no POST, RAM error beeps

No RAM, AGP videocard, no POST, RAM error beeps

With RAM, no videocard, videocard error beeps

With RAM, PCI videocard, POSTs without issues

With RAM, AGP videocard, no POST, no beeps

Do someone think there a solution for that or is my board fautly/dead?

Which AGP graphics cards have you tested your Abit board with?
And do those AGP graphics work in other boards?

Just to verify, you are not trying to use a 2x AGP card in there? Or a graphics card that is too recent?
Something like a GF2MX should work (provided the board isn't defective, as you're already suspecting).

What does it do if you try to make it post with both a PCI and AGP graphics card??

Whats missing in your collections?

i can't fit a 3.3v card, i only tested some cards and all the cards i used to test the board works in other boards.

The tested cards are:
Radeon HD 3450 AGP (the card which originally came on that PC)
Geforce 4 MX 4000
Geforce 4 MX 440
Geforce 3
Geforce 2 MX 400
Radeon 9550
Geforce 6200
Geforce FX 5700LE

I tried with both AGP and PCI card, same issue as AGP card alone, the PCI card i used to test is an old S3 Trio64
