I recently got a problem with my computer directly after attempting to replace my RAM. Once I replaced the RAM and plugged the computer back in, I got a long, repetitive beeping noise coming from the computer. In addition, none of its external ports, such as USB or the monitor appear to work. I tried replacing the RAM with the old ones, but I got the same result. Does anyone know what could have caused this?
One more thing. When I do start it up, it seems everything inside is functional. I can hear the fan spinning. I see all of the lights on the outside, and the cd drives work.
