Hi, I recently have changed some settings in bios, something from the CPU section, and clicked save and restart, it didn’t work, this has happened before and I did what I did, take RAM, in and out, and same thing with CMOS battery.
It didn’t work
I looked everywhere, but mostly I got “ take cmos battery out then put it back in”
Also my power button doesn’t work if I try to turn it off.


GPU: GTX 1050
CPU: AMD FX 4300 (or something close to that)
If anyone has answers I’m all ears
