Slow PC on games with great specs can't figure out problem

Hey guys, to start off I used to mine ethereum on my pc 24/7 which probably wasn't healthy... SO to startI have an i7 13th genMSI ventus 3080 10g oc32gb ram2tb hddI'm tryna play fortnite but my fps is choppy, i can't figure out why cuz i have decent specs, i've tried many things. XMP worked for a minute but my pc no longer turns on with xmp on so i had to take it off. need something to help speed ram a bit i know if i can ++ ram performance i'll be good. via /r/computers https://ift.tt/GIlSaco
