So earlier today my friend turned off my computer using the switch on the power supply and when I restarted it this thing called CHDKAK (This is wrong but something like it) came on and going through these 3 steps. I've been searching all over the internet for a fix all day and cant seem to find one and i really cant remember all the stuff it did but i remember it removing "orphaned files" and like validating stuff for some reason. After this happened all of a sudden my frame rate in every game went down the toilet. I used the open hardware program and I noticed that my GPU Memory is way low (I have a gtx 770). It is 3506MHz and it should be around like 7010MHz i believe. Although when I used a benchmark software everything got really low scores compared to people with the same hardware so I'm thinking that for some reason my computer is not getting enough power. I have a new 850w power supply I just got today and it was working earlier so it cant be that so im just really stuck.
