First problem - leaving your PC on 24/7.
Ok, I leave my PC on 24/7.
I came home this morning and it was off.
This only happens when we have a power flicker.
But, we did not have one.
My PC smelled burnt, electrically burnt.
I open it up to see and anything was cooked.
I did not find anything.
So, I connected it again and ran it.
While booting, a display came up about a problem.
Should have wrote it down.
I ignored and had it keep booting.
Now it is running very slow.
The "System" process is >90% constantly.
Is there any diagnostic I can run to see what the heck is going on?
