Did brown out just kill my CPU?!

Brianz72

Just had a quick flash brown out during storm. My otherwise perfect PC of just over a year, running an i9 chip on Asus ROG Maximus XII, seems instantly damaged. Still running with RAM RGB lights and fans, and I hear normal drive sounds during boot, but motherboard is giving me error 7F ("reserved for future use" per manual) which then changes to "Check CPU". Meanwhile, monitor display is blank, no signal. How do I even begin to troubleshoot this, short of swapping out the CPU?? Please help! I've done cold reboots to no avail, same result. Thanks for any suggestions.

Hi Brian72

Try shutting down your pc and turning off the psu switch for a few seconds, turn it back on and see if things return to normal.

Normally, psu's have protection against this.

Could try reflashing the bios if that doesn't help.

It worked!! Thank you! I hadn't tried unplugging the PSU and switching it off physically, just shut down / restart. Now I need to get my blood pressure back down. Thanks again!
