Yesterday, I got a balloon notification saying that there were some Windows Updates available. I like to keep my PC up-to-date, and since I wasn't in the middle of anything urgent I had my Windows 7 32-bit PC download and install them. WU asked to reboot my computer, so I got to a stopping point and clicked reboot.

When I rebooted my PC, my 2nd monitor stopped working and wouldn't detect.

So I downloaded installed the latest drivers and restarted, nothing. Tried rolling back to a restore point before the updates, nothing. Uninstalled the video card and rebooted, nothing.

I have an ATI Raedon 3600 Series video card, installed into a Dell Optiplex 360, running 2 Dell 19" LCD monitors. Nothing super fancy or extravagant going on here.

I am a bit at a loss. I was going to maybe take out the video card and try reinstalling it physically and "softwarically". But I do not think that will actually help. It was working fine for months, and so I am guessing it has something to do with the Windows Updates that were installed.

Anyone else experiencing similar issues? Anyone have any ideas?

Thanks!

I tried installing a new video card, which wasn't much luck. But after I put the Radeon 3650 back in the internal video card was detected. I hooked up my second monitor to that one, which since I do not run any graphics intensive programs on this computer isn't a big deal.

Not my favorite fix, but it works so. Yeah.
