MK79G-1394 works with onboard VGA, not with AGP

Great little m/b, but the onboard VGA gets me a 3DMark01SE score of 3050
with a 2500+ processor, whilst my old AK33 with a 900 Athlon got 3151 (with
GeForce2 GTS).
So, installed a GeForce FX5200 from a friends' PC that has been experiencing
some glitches in games, and I can't get anything out of the PC with this, or
an older GeForce2 GTS installed.
Am I doing something really obviously wrong. Can't see any jumpers or BIOS
options to switch between the onboard on AGP. No beeps, no monitor clicks
changing freq, nothing

Any suggestions anyone, or have I got a duffer?

 

There is a BIOs setting to enable the AGP slot. I believe it is under the
integrated peripherals menu or maybe the advanced chipset features.. It
should be something like "first init display" and the options should be
onboard or agp slot. It is there, I'm just not exactly sure where.

There is such a setting, but the options are:
1) Onboard/AGP
2) PCI
I have it set on 1) which seems logical - though I'll try the other, nothing
to lose

 

Nope, as I thought, the PCI option doesn't work either

 

Ok, the onboard/agp setting is what you want, like you said. This is a
longshot, but make absolutely sure that the video card seats itself properly
in the slot. Some cases cause the video card to cock slightly in the slot
when you tighten the screw down. I have seen this on more than one occasion.
It's definitely a strange problem you have going there. If it still doesn't
work, I would try flashing to the latest bios and see if that changes
anything. I didn't see any fixes listed for a similar problem, but you never
know. If that doesn't work, I would contact AOpen because you probably have
a board with a faulty AGP slot.

Thanks for the input. Did all that already. Sorry, should've mentioned it in
original post.
Getting an advance replacement board tomorrow. I'll repost with the results.
Thanks for the info. At least I know I wasn't going mad!

Sorry for a little bit out of topic.

I just wanted to know where you bought your motherboard from ? I've
searching at newegg, and directron, but can't find this particular
model.

TIA

Sorry for the late reply, PC been offline whilst doing some DIY!
Get it from CMS Computers, Liverpool. Listed in Aopen's official channel.
Trade only i'm afraid. I opened an account years ago when I did sell/repair
PC's, and they're still happy to deal with my one order every three months.
I seem to remember Dabs have just started doing Aopen. Not bad prices
either.
