After waiting for my new gpu to arrive and putting it into my case, i went to turn my pc on... Nothing, checked and rechecked connections, nothing... I went out and bought a new psu, put that in and nothing... The computer wont power on at all! I think i may have killed it somehow... I made sure to get rid of any static before working on the computer. All that happens, is the fans twitch and thats it.... Omg please help me
