I installed a video card but forgot to disable the onboard video for the motherboard (Gigabyte GAM61SME-S2). The monitor only says "no signal." I took the video card out and plugged the monitor in to the motherboard's connector, but now I still get no signal. I've tried (among other things) clearing the CMOS, but I still can't get a signal to the monitor. All I can think is that the motherboard was damaged when I started up with the video card installed and the monitor hooked to it.

Re: No video signal
That does not sound likely. how old is your computer? if it is more than about 5-6 years, it may have a blown power supply(basically your computer is dead) this happened to my friend's computer while i was there and he blamed it on me, if you think you caused it, don't sweat it. it would have died anyway! to prevent this from happening in the future:
-get a high powered one(450-800watts) -replace it before it goes, not when it goes(so, when the pc reaches the 5-6 year mark) -back up all your data to a usb hard drive that is not connected to your computer(network storage, etc.) make sure it is at least 250gb, if not 500gb to make sure you have enough room. -make sure the computer doesn't get too hot. if you are not too sure, download a program called speedfan. use it wisely, and if you don't know what something means, don't touch it until you know what it means.

Sounds like the video card is bad...the system beeps to warn of a failure on the mainboard...if this system has onboard video then you may need to disable the onboard video in the bios and then install a pci video card..otherwise the motherboard may need replacing
Verify the computer and monitor has power and is actually turned on.
Not turned on? Well… turn it on. J
No power? – Make sure power connections are in and secure. Reseat them to verify.
Make sure their power bar is on. (If they have one.)
If the monitor still has no power, try it directly to the wall and another outlet.
Still no power on the monitor, RPL if in warranty and is the original monitor or Op sale a new one.
If the tower has no power, try step 5. If still no power see No power troubleshooting.
Verify the connections are secure. Reseat them to verify this.
Remove the monitor connection from the tower, check if the monitor self test appears. (If may take a few seconds) If it appears, the monitor is fine. If it doesn’t, bad monitor!
Replace it if in warranty (and is the original monitor) or Op sale a new one!
Does the owner have picture in POST (Power on Self Test) or in the Bios? Do they lose it as soon as Windows loads? (If the computer has no POST or Bios go directly to step 7)
If they lose picture as soon as windows loads, boot to safe mode
Check for multiple video adapters, if there are two, try disabling the one the user is not using. (Usually a problem with onboard video overriding a video card).
If they are exactly the same try uninstalling one and rebooting. It might be a ghost driver.
If the ghost driver reappears after rebooting, try disabling it like it is a device. (Because it might be.)
If only one device is listed, uninstall the video driver. Reboot the PC and install the driver off of the driver disk.
If the issue repeats, uninstall the video driver again, get the user into windows normally and Doc-express them the updated driver. Give the SR# and your audix. If this issue happens even with an updated driver, you are looking at service for a potential hardware issue.
Do a hardware reset: Unplug the power from the wall and hold the power button in for 20 seconds. Try and boot. Check for onboard video as well as a video card. If the owner has both, try the onboard video. If it works. Check the device manager and try installing the video card properly. If it is installed properly, try disabling the onboard. Then switch it back to the video card. If the PC does not have both onboard and a video card. Proceed to the next step.
Open the tower and reseat the video card. (Make sure the owner has the power off and unplugged. Also make sure they touch a metal part of the computer to discharge static (IE the metal frame or power supply)
Still no video after reseating the card? It may be the video card or something on the motherboard.
Remove the video card completely and try booting. Does the motherboard beep? If it does, the motherboard is fine and you should replace the video card if in warranty. If out of warranty, op sale a new one. If the motherboard does not beep, it may be a bad motherboard or something attached to it. (Note: Not all motherboards have beep codes, check the source!)
If you are unsure if the video card is actually causing the problem, service may be the best option
Connect the monitor to the onboard video connector first. then
you need to disable the on-board graphics in the BIOS save the setting and shutdown. Then connect the monitor to the GeForce video connector and boot up then you will get a video signal on the GeForce video card.
first install the video card in the pci slot first so that you have access to your monitors screen for you to disable the on board video chip or video card, go to the CMOS setup by pressing del key. once there you can browse through the CMOS setup to disable the on board video chip.
