No signal graphic card

[chriszzz1]

My pc that I have used for 4 years suddenly crash last night. When I restarted the pc the monitor won't detect it and only work when I re-attach the monitor cable to the motherboard.

Which I concluded smthing happen with the GPU. The GPU fan still working and all the GPU light color are all green.

Any suggestions on how to fix it? 

I tried cleaning n re plugging the GPU n it still doesn't work.

Thanks

Check to see if your PC can even recognize the card to begin with, I would recommend using the BIOS or Device Manager on Windows (If you use Windows)

Your BIOS may be configured to use the integrated graphics on the mobo instead of the dedicated graphics on the GPU. Check those two things and then respond with what you find. System specs would also be greatly appreciated and helpful.
