Windows 7: (vga) monitor displays no signal

30 May 2011   #31

Windows 10 Education 64 bit

You've got nothing to lose now, I'd put the new video card in, connect the monitor to it, and see if you get video. Some BIOS will auto detect if you have an add-in card installed and switch on their own without having to go in and change a setting. You didn't say which manual said you had to change a setting in the BIOS, I'm guessing it was the manual for the video card. Either way I'd try it at this point, you might get lucky.

I would do the following in this order:

1) Turn the computer off
2) Unplug it
3) Remove the CMOS battery (looks like a watch battery; on the motherboard; note which side is up before you take it out)
4) Move the CMOS jumper back to the 2 & 3 position
5) Wait about ten minutes
6) Move the CMOS jumper back to the "normal" 1 & 2 position
7) Replace the CMOS battery - don't put it in upside down!
8) Plug it back in
9) Pray it works

Make sure you do them in this order, especially the ones I underlined.

If still no luck, you might as well put the new power supply and video card in and hope it works.

EDIT: alphanumeric types faster than I do. He gave you good advice, but I might try the CMOS reset one more time since it's not clear you followed steps #2 and #3 when you did it before.

What happened? You didn't use the Winchester on it, did you?
