The processor only works on one core

1,309 Views

If there are more than one active processor cores in bios, then the computer does not boot further bios, just after the motherboard logo appears, the blue screen pops up and the computer reboots, if you set the number of active cores 1, then the Windows boots up normally. After the purchase, everything worked perfectly for 10 days, then a blue screen popped up during the stress test AIDA64. Errors are always different.

Hello laur601

Thank you for joining the Intel® community.

Have you tried contacting ASRock* to restore BIOS to default settings and verify if there is any BIOS update require?

Hope this help.
