So today a wire got caught in my chair and pulled my desktop over when I turned. It fell about two feet. The computer froze so I turned it off. After a few minutes I turned it back on and now it runs very slow. I checked to see if everything inside was secure and/or broken and everything appears fine. The ram was not registering so I removed all but one stick and now after another reboot it seems to be working like normal except I got a error on start up: ORCA Write failure(23). I'm guessing I may have damaged my hard drive?
