Basically a friend of mine is trying to fix his computer by removing his graphics card (Refurbished GTX660 which I told him not to buy because of lack of warranty). I instructed him to uninstall the drivers to his 660, then shut down, remove the graphics card, boot again, and install the integrated graphics drivers after that. He skipped the remove graphics card part and installed the AMD drivers for his integrated graphics, while this is happening the DVI adapted cable (DVI to VGA) was still plugged into the 660. At this point I did not know this and he's restarted his computer and the monitor won't turn on because there's no signal it seems. I've tried everything I can think of and the monitor won't take any signal.... Ideas?
