CPU: Intel I5-2400 Mobo: Asus P8H67-M Pro RAM: 16G DDR3 1333 Graphics card: MSI R5450 Windows 10 Home
I left my computer on sleep overnight. Next morning, I roused it and it made all the normal clicks and whirrs, but the monitor was totally dead. Not even a 'no signal' warning. I replaced the monitor. No luck. I removed the graphics card and plugged the HDMI cable into the onboard HDMI port. The BIOS screen appeared, and then the small, all-blue, 4-panel Windows logo showed up for a few seconds, and then the screen went black again. I kept doing this for a while. Twice (out of tens of times) I switched the monitor off and on and my full, normal Windows desktop suddenly showed up (just on those 2 occasions) for a minute before the screen went black again. But usually, after the BIOS and Windows logo, nothing. So I replaced the power supply. No luck.
