I built my computer, it’s worked fine for months. Now: sudden “display not found” and fan spins wildly. Have to press the “on” button to shut down. I have windows 10. ASUS 1080ti. Intel i7-7700k. Nothing running hot, happens from cold start. Suddenly happening a lot. Ran memory diagnostics, all good. Updated drivers for NVidia. Updated windows 10 to latest. When I reset, the icons on my desktop are shuffled. Also, couple times it came back on and was set to odd resolution (very low res and stretched) but restarting it helped. Any ideas?
