Dell T3500. Configured in RAID 1.
I've turned off sleep mode and all other power management settings to never have my PC turn off.
About once a week, when I walk up to my PC and move the mouse/keyboard, the monitor stays black and there is no response. I can't even remote into my PC. The PC is on and the fan is blowing. I have to do a restart in order for the PC to come back up. A week later, it does again. I have updated all drivers and still have issues

Im starting to think its the motherboard.

Ideas?
