wtf... that must be the first mobo which isn't identified by Everest....
Anyways, I don't see anything about an AGP slot... I do see you have 1 PCIe slot (?)....
Take that screenshot of your mobo anyways

and see if you can find the motherboard type number somewhere printed on it (usually the biggest text you'll find on the mobo)....
Also, see all the comments (read entire thread) in "
Intel Chipsets".

What you also can try instead of Everest is
CPU-Z. download it directly from
here, unzip it and run CPUZ.EXE... Within the program, check "
Mainboard > Manufacturer & Model"
