If you go to the Performance tab of Task Manager...double-click the CPU usage graph...how many cores are represented?
Double-clicking doesn't changes anything... if it booted up with only 1 core - it's like this permanently.
I'm not sure if it's AMD Processor Driver related (Cool'n'Quiet).
The only things that are bothering me now:
1. Case fan at rear, that I assume driver additional dust.
2. A little defect at the peripherals rear panel - one "metal line" is ripped out, that is not in use (technician's fault, was in a hurry).
* 3. Default BIOS settings, that are somewhat incorrect; USB mouse and keyboard are disabled, until I enable it. Accidently changed (not real defaults).
4. Time-to-time, only 1 processor core... that is somehow mysteriously related to constant, unexpected reboots.
Ahh... that's the first time in life (!) I can't figure out what to do. Can't fix it.
If only you guys could help me.
* = My motherboard is from GIGABYTE tech., they have something like "Dual BIOS". Maybe that could help me reset to real defaults?
