Hi Albert,

We can't accurately help you unless you tell us what make and model your motherboard is. You have only told us the socket name/number. Look around the board - usually in white ink also look for "Revision" or "Rev" or "R" with a number following.

But having said that if it is an Intel board:

3 beeps On-off (1.0 second each) three times, then 2.5-second pause (off). The pattern repeats until the computer is powered off.

Cause :Memory error

Solution:

• Reseat the memory.
• Make sure that the contacts on the memory and the socket are clean.
• Try removing one bank of memory modules at a time. (Some systems can require a memory module in Bank 0.)
• Try using memory modules from the same manufacturer with the same part number and speed.
• Check for a faulty memory module by trying the memory in a known good system.

Older Board:

1 long beep followed by 2 short beeps Video configuration failure (a faulty video card or no card installed), or an external ROM module does not properly checksum to zero.

3 beeps First 64K memory failure.
