Thats why. No offense, but that card is
extremely weak. I also suppose its an onboard video card too?
If I was you, I'd go out and buy at
least a 8XXX series card or just something that will work
with your motherboard period. You could shoot for an ATI card too I assume but either way, I'm not sure what will
work with your motherboard, power supply, etc. I know a Geforce GTX 430 would possibly work and they are fairly cheap.
