Hello
Recently, i took off the hdd of my old pc to retrive data. Then I replaced it on the central Unit. When I power the PC ,it turns on,i hear everything running. But the display doesn't show anything and keep black. The display works well, I checked and the HDD is working well on another PC

Would reseting CMOS of the Motherboard works ?
If so here's my motherboard (G31t-m9)

I've seen people using the jumper, how can i do it here ?
Thank you for help

Open the system case again and check that you haven't accidentally pulled a small connector off the motherboard when you removed/replaced the hard drive.

If you have an add-on PCI/PCIe graphics card in your PC, try reseating it but do ensure you observe the standard precautions regarding electrostatic discharge before you touch the card.
