Im a little bit dumb. So my original version of the bios is 1.7 and i upgraded IT to 2.8 version. After i did that my mouse became numb and IT scared me that i lost the PC
I installed a 1.8 version in bios but the problem continues. I want the bios to be in the original state IT was when i bought IT. Can i do Something and reverse the bios version to the original state?
