Hi, the issue could be related to UEFI BIOS. What is your exact motherboard make and model? System BIOS version? If you could PM me your Belarc report, I cold check this out.
Yesterday, I updated my DELL BIOS.
Afterwards, I turned off my computer and several minutes later turned it back on again. Everything was fine and it looked the problem had resolved itself.
However, when I booted up this morning the problem has returned.
