Got a Z370 gaming 7 motherboard. Flashed the BIOS through a USB in BIOS. For some reason every few months or so, my motherboard will randomly go back to the last BIOS flash i had. I used to have F5m and updated to F7. I was fine for 3 months. Today i noticed my RGB lights were all different colors on the MB. So i turned off my PC. Lights were only still on for the motherboard. Unplugged the power. Waited for the power to drain, it did. So then i plugged it back in and turned it. Checked my BIOS to see if everything was alright... It's back at F5m. I'm getting tired of flashing BIOS back to F7 or now the current one that is F10.
The weird thing is, when i was at F5m, it would sometimes reset back to F4 which is the revision it came with on the board, I had to flash back to F5m from F4 once in a while too.
CMOS battery or BIOS corruption?
It's still on warranty too. So, yeah.
