I bought a new motherboard and when i put in the 6600gt, there is no signal. While the 6600gt card is still in, if i switch the vga cable to onboard, it has signal and shows windows booting. I think there might be a problem with the psu (6 years old) as it is old and only has 300 watts or it could be a motherboard problem but im not sure. The 6600gt works on other motherboard that is old.

MSI GF615M-P31
AMD Sempron 145 2.8ghz Sargas
2G DDR3 PC10600 RAM
OCZ Onyx 32gb SSD
PSU 300W
NVIDIA 6600GT 256MB

This. Take note it should be under a heading called "Primary display device" or something similar.

Then remove the dedicated video memory in BIOS to allow you to use the 2GB RAM you have to full capacity.

Although ive already did all of this, it still does not work. Today, I also got a new psu 500w so we can rule that out. Im probably just going to assume that it is a defective motherboard. Thanks guys for your help.
