I was using my custom built PC earlier and I accidentally dropped my phone on the top of it. After that happened the computer just froze. I restarted the computer and it just started up, shut down, and kept restarting over and over. I then shut it down again and it started to work. About ten minutes later it froze and then gave me a blue screen crash. I then tried to reseat the RAM but one of them won't click in. Does anyone know what could be wrong? Please help me. Thank you in advance.
