Three beeps is normally a memory problem.


Unplug the power cord, lay the tower on it's side (I assume you have a tower?) & take out ALL the RAM. Take the original stick & run a pencil eraser along both sides of the contact edge, then wipe it with rubbing alcohol. Make sure it's 100% dry before reinstalling it. Take a good close look at the memory slot & at the contact edge of the RAM...notice the 2 notches? Make sure they line up when you insert the RAM in the slot. Push down firmly until you hear it click in place & double check that the locking tabs on each end of the memory slot are fully locked in place. Plug in the power & try booting up.
