Recently, I had to buy a new psu because my old psu was 500w and would just randomly shut off because I was told that my graphics card was to powerful for my psu. So I bought a new 700w psu and installed it and now my computer won't recognize my keyboard or mouse but it'll recognize other usb devices. I cannot enter BIOS because the keyboard won't turn on at all. Also my computer keeps going into start launch repair and then I get a blue screen once it enters the repair.

I tried disconnecting all the chords and reconnecting them. Everything I've tried hasn't worked.
