I had this computer for about 5 years now about 4 years ago I opened it up and took the rams out and tried and put them on my other computer withc was a tower, then later on I threw out the tower computer and took the rams that was in my dell computer and put them back in back then from then on i never used this computer and now when i want to i turn it on and 6 long beeps come up and nothing shows up on the screen, When i boot the computer it had no keyboad just mouse and screen connected.
