Hello, sorry if this is the wrong category but i am getting desperate and i really want to get this fixed. I built my pc around December of 2016 and it didn't start having these problems until about a month later, if i am using my headphones as speakers it emits a short screech and then the computer freezes and the keyboard back lights shut of, if i'm using my surround sound speakers, it emits a continuous screeching noise and the same thing happens. it happens about once every day for some reason though it seems to only happen when i play league of legends, i went a week without playing it and it didn't crash once, although i have no idea if that has anything to do with it. I need to know why it is crashing and how to fix it.
my specs(just in case it might help) are
cpu: i7-6700k (not overclocked)
motherboard: asus rog maximus hero viii
ram: pny anarchy 2133mhx (i think)
gpu: 2 gigabyte g1 gaming gtx 1070 in sli (i have sli turned off although they are both plugged in and teh sli bridge connecting them)
Hdd: 2tb seagate, 2tb toshiba
cpu coller: corsair h100i v2(i think its v2)
powersupply: evga supernova 850 g2
