Changed Bios Video Settings--Now no display

September 2, 2014 at 13:30:10
Specs: Windows 8.1
I was messing around with the video display (can't remember exactly what it is called) settings in BIOS. I changed it to something like INT Graphics. I saved the change and rebooted. The problem is that I get nothing on the screen when it boots. I hear the beeps and everything looks fine, just no display. I've tried plugging into my motherboard's display ports and the display ports in my graphics card. Removed graphics card, etc. Nothing gets a picture.

Tried to resent BIOS with the jumper. Also removed the CMOS battery. No change. I can't go into the BIOS menu because I can't see anything on a display. I'm concerned that I've bricked my motherboard, and will need to get a new one. Anyone have any ideas before I do that?

Is there by any chance another monitor socket on your computer for its internal graphics?

EDIT:
Ooops, sorry, I see you've already tried that.

Always pop back and let us know the outcome - thanks

I'm assuming that you mean the DVI and VGA sockets that I used before I put the graphics card in. Yes, I've tried those. No picture.

See my EDIT to #1 - didn't spot that you'd tried that.

If it was a display card BIOS setting I would have expected the monitor to say "No Signal". If you see nothing at all maybe its a monitor issue or its plugs and sockets. It would be worth eliminating this possibility by trying another monitor, or yours on another computer.

Always pop back and let us know the outcome - thanks

Thanks. The monitor actually does say no signal, which is different from what it says when the cable isn't plugged into anything. Should have specified that. So it recognizes that the other end of the cable is plugged into the socket. But it isn't getting a signal. I've tried four monitors so far. I'm pretty sure it isn't a hardware issue. I changed the setting and then BAM, no picture. The problem is that I can't get back into the BIOS menu to change the setting back without a display. I've tried the hard resets (CMOS jumper, removing the CMOS battery), but none of them solve the problem.

I understand your dilemma but have never known BIOS settings to brick a mobo (only BIOS updates). You usually get "something" on the screen. Better keep looking out for other folks ideas on this one.

In the meantime (although I'm not at all hopeful) you could discharge the motherboard. Disconnect from domestic power and remove the main battery if it's a laptop. Hold the Power Off/On button in for about 20 seconds then re-assemble and try. I think you might need to cross a lot of fingers but at least this procedure is easy to try. Check from all monitor sockets as before.

Edit: sorry I've seen you have tried removing the CMOS battery and using the reset jumper. Did you hold in the power button while the battery was removed? This discharges any stored charge in the capacitors.

If it's a desktop you can try resetting the BIOS by removing the CMOS battery and pressing and holding the power button for around 15 seconds. Do this while the computer is completely disconnected from any power source of course.

Also on some motherboards there is a clear CMOS jumper which can be used instead.

Just double checking to be sure: Did you remove the AC power plug before trying the CMOS resets? If not, try them again.

INT Graphics should have been internal graphics which should have worked with the motherboard's graphics ports unless you happen to be using a DVI to VGA adapter which only works on DVI-I ports and not on DVI-D ports which do not support the feature.

Is is possible that you changed the settings from PCIe 16X to plain old PCI? This would require a PCI graphics card to get any signal. Of course, the reset should have changed it back to factory defaults as far as the graphics are concerned so after that, one or the other of the graphics ports should be supported.

Last thought: If you are using display port or HDMI ports, try the VGA or DVI ports to see if that makes a difference.

You have to be a little bit crazy to keep you from going insane.

Yeah, clearing the cmos--correctly--should have fixed that. If you still can't get it going, remove the add-on video card and try just using the on-board.

Don't forget to preorder your Hatch green chili for this fall. Many vendors ship world-wide.

I agree with DAVEINCAPS #8.

To reset the BIOS correctly, make sure to unplug the power cord, then use the clear CMOS jumper (there's no need to remove the battery). Just move the jumper from its normal position to the clear position, wait a few seconds, then move it back. Make sure the graphics card is removed & the monitor is connected to the integrated graphics port, then try booting up.
