My pc started freezing one year ago. I tried everything including redownloading windows and that didn't work. So I took out the GPU (a used GTX 770). I used the PC's onboard graphics for about 3 months until one day I put it back in and it worked. It has been fine for about 10 months until last week it started freezing again. I took out the GPU and it is fine running games(just way worse frames). What part of my PC is broken and needs to be replaced?
