I have an appointment with Microcenter tomorrow. I had the PC fully off since yesterday, switched off at the power supply. Curious, I switched the power supply back on and pressed the power button to see if my PC would boot.
It did, as I'm on my PC right now. The date and time were wrong at boot, but once Windows loaded the date/time corrected itself.
I'm suspecting a BIOS/CMOS issue. However, this system is still going to Microcenter. LOL.
