This is my friends pc, my pc has the problems. A few days ago I wanted to upgrade my ram so I bought the ram from another friend (my pc is a Dell Inspiron 560 with 3GB of ram installed I wanted to add 2GB of extra ram, 1333-MHz DDR3 DIMM is what I added) It was tested and was compatible. Anyway all was fine shut the pc off went to turn it on the next day now it won't boot, there are 2beeps and a flashing amber light.My friend went on another forum and everything they told him I should do I did but nothing has changed. One thing they said I should do was remove the extra ram which I did but the pc did not revert back to before I installed the extra ram. Maybe ther's something I can still do to get my pc back. I realize I made a mistake so maybe you can give me some advice thanks.
