I recently tried to fix an old pc i got and I installed a windows 10 on it. It worked fine and I put the pc aside for a few weeks. Today I tried it again and it worked , but when I wanted to do a restart , it got stuck and started auto repairing. Did this a few times but nothing would start windows again . The first boot worked and I even games on it for 2h , no problems. The problem started when I hit the "restart pc" option.

Since I couldn't figure out the problem , I even did a full reinstall of windows 10. Gues what : It booted perfect , I playeda game for an hour , pressed the "restart pc" option and again , it wouldnt boot and started to "repair".

I dont know the mobo out of my head. I use a Ryzen 5 -3600 CPU , 1070Ti GPU and 2 sticks of 8gb RAM

What could cause this problem where a fresh windows install works on first boot but wont boot again when i use the "restart pc" in windows ?


EDIT : Seems I found the (weird) problem. The GPU has 1 HDMI , 3 Display Ports and 1 DVI connections. I was using the HDMI and the DVI. When I unplugged the DVI , PC starts and restarts normal. I tested the same screen (that was connected with DVI) but with Display Port cable now and the pc still worked good. To be sure , I used a third screen and tested first with DVI cable and than with Display Port. Same result.

Seems that the GPU has a bad connector (the DVI) and that that was causing all the troubles. I had red about people who had problems restarting a pc etc , but never saw any mentions of a bad GPU connector beeing the problem.
