My grandfather has a hp 6210f something is wrong with the integrated graphics so we got a radeon hd 5450
cleaned the pci slot with air (because its never been used) plugged in the new gpu went into setup disabled the onboard graphics, computer started up put the disc in i tried to restart and boot from disc wouldn't work i tried running the disc said it couldn't find the card the screen got these vertial pink and green static lines. felt the card was really hot. what do you think the problem is.
