Question Hard Freeze when Monitors Reactivated followed by Boot Error on MB.

[lemonhead72]

My PC will experience a hard freeze when I reactivate the monitors, usually after overnight. I have my system set to not have my devices sleep, and the monitors to shutoff after 3 hours. I can tell the freeze occurs at that moment because of the time displayed.

The PC then requires a hard shutdown. Complicating matters is upon reboot, I will get a red light boot error on the motherboard and it will fail to boot. I will have to force another shutdown an restart - after 2-5 tries of doing this the PC will then boot normally - or occasionally give me a screen acknowledging the boot error and ask if I want to load optimized BIOS setting/go into BIOS etc..

This has been happening occasionally since I bought the PC last year (maybe once every 7-10 days), but is now increasing in frequency to almost daily. Any other manually induced shutdown or restarts occur normally - the boot error only occurs after the issue above. I have installed the latest drivers for the video card etc. to no change. I typically leave my system on all the time.

Any advice as to what may be causing this or how to fix would be appreciated.

What power setting do you use in Windows?

 

[lemonhead72]

Power Mode = Balanced
Shut Screens off after 3 Hours
Put Devices to Sleep - Neve

Try using high performance for troubleshooting. This changes many settings. See if it helps at all.

Had another freeze this morning (after changing power management to high performance) - though it did boot normally this time. Not sure if that is a coincidence or a trend yet.

Try going in to bios and under advanced disable any power saving settings. Also enable power to usb setting for soft state (s5). See if this helps the freezing when put to sleep.
