Inspect the monitor video connector for bent pins:
If any of the pins are bent, replace the monitor connector cable.
If no pins are bent, reconnect the monitor connector cable to the
computer.
Ensure that the video cards are properly seated in the connection slots
on the motherboard.
This beeping is called a POST (Power-On Self Test) error code.
Record the pattern of beeping (ex.: 3 short, 1 long, repeating). Error
codes vary from system to system, with the exception of a few codes
outlined in the following list. Some motherboards are equipped with a
small character display that prints out a code accompanying these
beeps. Record this code if available.
1 short beep: Normal start, self test passed.
1 long, 1 short beep: Problem with motherboard.
1 long, 3 short beeps: Problem with video card.
1 beep, repeating: Problem with RAM.
Continuous beep: Power connection to video card(s) dislodged or
disconnected.
Try removing your video card(s) and reseating them. Also try removing
all RAM modules but one, powering on, listening for error codes,
powering off, adding another, etc., recording notes as you go. Contact
Customer Care after you have written down the code(s) and tried
reseating components, or require help doing so.
