I built a PC to sell to my aunt for Christmas so she could gift it to my cousin. He’s not a heavy gamer so I put an FX 6300 and a 1050Ti in the PC. I was putting in the wireless internet adapter (pcie) and a hard drive after not turning it on for around a month. I know for a fact it worked before and a short while after the instillation. It turns on and it seems to be working just fine, but, it does not display anything on my monitor. My power supply seems to be functional and it seems to be more of a motherboard problem from what I see. However, I’m not too-well versed in the area of hardware troubleshooting. I have to have it ready at least a couple days before Christmas and the parts I’ll have to order will take time to deliver. Someone please help!
