Not all PowerSupply, works in the same way!
Some requires, minimum charge, to works correctly.

Ciao


This is true, sometimes you'll see on PSUs +5V 2-15A or whatever. It's not that common, but it does exist, and PSUs like that won't switch on fully as a safety feature if the required load isn't present.

@lionstorm

at this point, test the GFX card on a PC.

Then, you will be sure that the AGP controller of the mobo is broken.IMHO

Ciao

PS- sorry but . . .have you contacted the seller where you have purchased the A1 mobo?

Eyetech! where are you? :-D

@lionstorm

Out of curiosity, is your PSU a 'specially designed for Pentium 4"?

 Well, that is true...they only draw the power they need from the PSU..
 But it isn`t crap about the small PSU idea..
 Switched mode PSU`s need a minimum current drawn through them in order to give a stable regulated voltage. The motherboard sees a wobbly supply and waits until it reaches a decent level.
 If you use an ACME cheapo special PSU(TM), you`ll often find they need a higher minimum load to fireup than the well known quality brands.
 Add to this the fact that high power PSUs have a higher minimum load than low power ones, ( I`ve got a 145W micro ATX PSU here that only needs the load of a 2W fan to stabilse!) and it should make sense...
On schedule, and suing
