Hey all. I run an R9 390x GPU on a MSI Z270i motherboard, and while using the PC a few hours ago (not doing anything out of the ordinary, no new drivers or anything), the screen suddenly went black. I restarted the computer, and even though the fans and motherboard lights are active, I'm still just getting a "no video signal" message on my monitor.
I have tried:
- changing from DisplayPort to HDMI on the GPU (no difference)
- testing the monitor by connecting it to my old laptop (turns out the monitor and HDMI connection are both working fine)
- removing the GPU on my PC and trying to connect the monitor directly to the motherboard, both through DisplayPort and through HDMI (no difference. Still just "no video signal". This is about when I started getting properly worried...)
- clearing the CMOS (no result)
Any ideas? The one time something similar to this has happened, it turned out that my GPU had gotten unseated somehow. But that's definitely not the case this time -- I've re-seated it twice now, and the GPU fans are spinning when I turn it on, so it's clearly connected. My keyboard lights up when I turn it on, so power is still going to the peripherals. I've currently got the GPU unseated, but I'm just getting no video signal no matter what I do, and so can't even access the BIOS. Any help would be enormously appreciated.
