My Nvidia GeForce 8600GT card that I have been using a few years randomly stopped giving any signal to my monitor. It had happened a few times before but a restart seemed to get it working. But no longer. I tried a different monitor with the same results, as well as using my current monitor on a different computer, and it worked. Upon startup the computer runs as if everything's fine, but the monitor only displays 'No Signal'.
I reverted to my on-board card that came with the computer, which has been working fine. But I'd like to get my better one working again. I've tried dusting out the computer and the card with a dusting air can. The strangest thing is that I tried booting the computer with both cards in (the on-board/original AND the GeForce) with the monitor plugged into the motherboard (NOT the GeForce) and I couldn't get a signal! It appears to only work when the GeForce isn't "plugged in"/attached.
A few searches have implied updating drivers (which I did occasionally when it was working), but it doesn't appear that I can update anything unless the card is actually attached? Does anyone have any suggestions/insight? Help is greatly appreciated! Thanks!
(Additional Note: I had also read things about changing a setting in BIOS. I checked it out and my 'Primary Video Adapter' setting under 'Video Config' was on 'Auto'. Not sure if that's pertinent or not. I believe other settings were 'IGD' and 'PEG')
