I encountered the strangest/most infuriating thing today. When I turn my PC on, nothing displays. I had this issue when I built my PC, but I fixed it. The problem back then was that my Mobo wasn't compatible with my RAM. I fixed this by using only one stick of the two that I had, but today it decided it didn't want to work anymore. I changed nothing on my system, and it was working fine this morning. I doubt it's my GPU as my monitor still turns on (gets off of standby) when I plug my HDMI cord in, so my monitor is clearly still recognising my GPU is there. Everything else still turns on also, so I don't think my Mobo is dead. The only thing I can think of is that my RAM isn't compatible at ALL now. Please help!
