Motherboard not detecting GPU

ridd21 · May 23, 2013

Hello,
I bought a computer a year or so ago and slowly upgraded it threw time and then rebuilt it using the same parts it came with and for some reason I can't get it to recognize the gpu now. when i plug the monitor into the gpu nothing will come up but when I plug it into the mother board the on board graphics works. I've tried unplugging the gpu and reinstalling it with no luck and even used another AMD card to make sure the other wasn't messed up but it also didn't work. any thoughts?

Did you break any of the gold contacts??????????

If you do you just wasted a GPU =(

If you did... then reply I might be able to help

nope they are fine

hmm. i had the same problem with my 7450

did u plug in all the pci e connectors and the supp connector

when you put in the gpu press firm pressure on both sides so all the contacts can go in

No output on either the GPU or the motherboard?

Its a 6670 from powercolor and doesn't have a spot to be plugged in by the pci-e but the fan runs when I turn the pc on but for some reason the motherboard wont detect it.

That is either the monitor or you did not plug the dvi in right... other then that Im out of ideas

Sorry =(

I've used two different monitors and it didn't work but both monitors work with my primary comp.

Does the computer boot with the onboard graphics with the GPU plugged in? With normal video?

If so, then it might be as simple as setting the primary video to PCI-E in the BIOS.

smeezekitty :

yes it will boot with video if the monitor is plugged into the motherboard on board graphics but when you hook the monitor up to the video card and boot the comp up nothing comes on the screen just stays blank.

Go into the BIOS setup and look for an option for default or primary video.

Reset Bios/Clear CMOS, that usually does the trick when a GPU isnt detected

How do I clear the CMOS?

smeezekitty · May 24, 2013

ridd21 :

There should be a clear CMOS jumper. But I will note that for my board, I needed to manually set it to PCI-E.

what is your motherboard make and model

notea :

Gigabyte GA-M68MT-S2

first thing to do is clear CMOS, you can do this by taking out the Clear CMOS jumper or taking out the CMOS battery, next thing is, go into bios and do it like this BIOS>Advanced Bios Features>Init Display First>PEG ...save and reboot

OK going to try this now! Thanks notea.

When i reset this will it reset all my desktop and my program-mes? im not very tech savvy as i havent got my windows 7 cd

thanks in advance

Two year old thread...

It won't affect anything in the hard drive but it will mess up your BIOS settings when you clear the CMOS.

They defaults may work okay ... or they may not.
