Hey, have a problem with my parts (guessing it's the GPU). PC wasn't able to start ( previously it crashed while I was gamin, horizontal lines where everywhere had to restart, it didn't want to start), I went into Safe Mode and deleted the AMD drivers (even in Safe Mode the screen had vertical/horizontal lines), I restarted it and the PC turned on but there we're still lines all over the screen, I also tried opening the BIOS but the PC just freezes, is it a motherboard problem then ? (I don't know much about PCs he). Later I tried plugging the monitor cable into the motherboard and the lines we're gone (but then of course I can't use my main GPU for gaming). Can it be the PSU ( It's an Raidmax Cobra RX-600AF-B 600w ) that's not sending enough power to the GPU idk ? Also if the GPU died, can I get an RX 580 8gb Nitro+ on a GA-H81M-D3H motherboard ? Sorry for asking a similar question again, I just want to be sure, Thanks!
