i would like to know if the chipset would in anyway affect a new video card. when i bought my computer it came with a 1gb nvidia geforce gt 220 but a psu of only 250w. this i think somehow damaged the video card (it doesnt work now, i tried the gpu on another computer). i was also wondering if a broken onboard graphics chipset could afffect the new video card or damage it. i know i have to replace the power supply in order to get a decent video card, but i would like to know if i HAVE to replace the chipset (if even possible) or the entire motherboard for it to work properly. I have an hp pavilon p6607c
