Using the manual for the Gigabyte GA-945P-S3 MB. Go to page 71 & you'll see bios beep codes for your board: AWARD BIOS Beep Codes 1 short: System boots successfully 2 short: CMOS setting error 1 long 1 short: DRAM or M/B error 1 long 2 short: Monitor or display card error 1 long 3 short: Keyboard error 1 long 9 short: BIOS ROM error Continuous long beeps: DRAM error Continuous short beeps: Power error As you can see there isn't a code for three short beeps. When you boot your system try to pause your boot up screen. See if the bios is reporting the correct total of memory in your system. Bios codes from the link below. http://www.computerhope.com/beep.htm#05 3 beeps for the AMI bios code reports Base 64K RAM failure. You can test your memory. Go to memtest.org Scroll down the site to just under the three screen shots. Download Memtest86+ V2.11 You have a choice in making a bootable floppy disk or a bootable CD-ROM disk. Once completed you boot your system to the testing program. Memtest will check your system memory. This should help. Thanks for using FixYa! Mike

Hi,
From the description of the problem, it seems that either the power switch of your PC or the power supply cable is faulty. Also, please let us know if the motherboard LED is glowing or not. Do reply for more assistance.

Thanks.

The one long beep, this has something to do with the video card.
Can't really tell without the BIOS you are using !
Anyway, try removing the card and replace it. ( with anything, just to check. )
This is a good board, I have a ASUS P4C800 and you can't beet it.
P.S. Make sure all your memory is the same freq. and clock speed.
Good luck.

The short then long beep error is indicative of a RAM memory issue. I had the same problem and had to use a process of elimination to determine the bad RAM. Place a RAM stick in slot 1 one at a time. The RAM stick(s) that give the short-long beep error are bad. If all RAM gives you the error it is more likely you have a bad board

Anyways here are the common beep codes for your motherboard.. it might help you too.
1. No beep - no reaction, the mother board is dead, power supply problem, processor and or ram problem.
2. 1beep - board is working fine.
3. One long beep then it shuts down - cpu problem, your processor is not working or missing.
4. 1short beep - system boots normally
5. 2short beeps - CMOS setting error.
6. 1long 1short beep - dram error
7. 1long 2 short beep - video card or monitor not connected
8. 1long 3 short beep - keyboard error.
9. 1long 9short beep - ROM error
10. Long beep - memory card is missing or not connected
11. Short beep - power supply error
12 Four beeps - there is no fan detected on Fan1 or Fan2 header. make sure to attach or reset CMOS bios to factory setting.
