I've just had an issue with my PC where i left it a while as i got engrossed in the TV, came back and monitor was in standby mode as you would expect, i moved the mouse around and nothing, it had all frozen. It's done this before and after resetting it's been fine, this time however it was failing to initialise any peripherals and the monitor. The fans were not kicking in properly and the red light was flashing in a particular rhythm. I know the mouse and keyboard werent initiliased as they both light up when on and the lights hadn't come on.
I tried switching it off completely, switched back on and same again, so i tried unplugging at the wall and unplugged the keyboard and mouse for good measure, still the same. I left it about half hour switched off at the wall and switched it back on. This time it ran and gave me a POST error stating that boot had failed and to check my settings in the BIOS. I did so, everything looked fine, so i continued. When prompted i selected start windows normally, and it booted fine, just perhaps a little slower than normal.
Once i was on my desktop i went straight to event viewer and the following events are logged right before the initial crash:
Error, Kernel Event Tracing, Event ID 3, Session "Power Efficiency Diagnostic Logger" stopped due to the following error: 0xC0000188
Warning, Kernel Event Tracing, Event ID 4, The maximum file size for session "Power Efficiency Diagnostic Logger" has been reached. As a result, events might be lost (not logged) to file "C:\ProgramData\Microsoft\Windows\Power Efficiency Diagnostics\energy-trace.etl". The maximum files size is currently set to 104857600 bytes.
Error, Kernel Event Tracing, Event ID 3, Session "NT Kernel Logger" stopped due to the following error: 0xC0000188

I'm assuming these events have something to do with the crash but i dont know what they mean. I did inspect my power settings after reading them figuring it may have had something to do with power and changed the setting for inactive hard disk to switch off after 20 minutes to 120 minutes. I wonder if that setting was what caused it, and for some reason the hard disk didnt become active again when i came back after leaving it a while?
I also wonder if it's simply my motherboard, im throwing that suggestion in because of the amount of CMOS batteries mine has eaten through over the last 7 years (4 or 5), and wondered if that is a contributing fact.
Any ideas/ help/ advice to prevent this from happening again would be appreciated thanks.
