I got 3 long beeps? after that no more display and

Hi,

Three beeps usually means problems with memory (RAM). In your case (no display) you might want to check the graphics adapter first (see if it's inserted correctly - take it out and put it back) and try again.

Also check to see if you have the appropriate kind of RAM for your motherboard and if it's been inserted into the slot(s) correctly. If you added a new RAM module to your computer, you might want to check if the new module is compatible with the old one - try running the computer just with your new RAM module first, then try again with both of them.

Take care,
Alex

Check the memory cards. Remove and reseat, if you have more than 1 card try them individually to identify a problem with one of them.
