i took my videocard out today to take some pictures so that i can upload them on ebay and sell it. when i put it back on, it wasn showing display. i tried it couple of times then it worked, but it become all glitchy.... it was wierd.... now im using the onboard gpu. i tried disabling and used my card but didn get the display. the fan is running fine. should i uninstall the current driver and install the driver that came with my card?
