Hello

I have a ASUS CUSL2-C motherboard.
It worked for me, with a strange problem: with Geforce3 at AGP slot, after driver install only 16 color 640*480 resolution worked. With other 815ep chipset motherboard this problem not happen (II tried same type of motherboard too.) With 3dfx voodoo3 already work, and with riva 128 too.
And occasionally isnt started the motherboard working, only fans work, but after a little waiting, and/or bios clear it worked again.
But after some testing it stay unworking state, status code reader (test card) show 00, so nothing happen.
This motherboard has some specific problem, or which direction would be a good starting point to repair it?
Thank any advice 😀
