So i've tried to switch out my gpu with an asus rog 1050 2gb, and what happened is on pc startup the gpu led flashes white (as it should) for a second, then starts flashing red, and the gpu fans stop spinning a few seconds later. After that the pc would restart and then do it again and again. On startup the monitor doesn't even power on, doesn't display anything at all and now even if i try to use the old graphics card i get the same results. The only thing that comes to mind is that i've probably short circuited my motherboard or my PSU when i was messing around with my cpu. Can anyone tell me if theese are sympthoms of a motherboard short circuit or more of a PSU malfunction and what would be advised for me to do next? (i'm on a very strict budget and i can't really waste my money on replacing both or buying tools to diagnose the issue myself)
