Have a Intell D865PERL getting either 6 or 7 beeps when booting, can't be sure which. System will not boot but just beep with PS2 keyboard installed but will boot with keyboard removed. BIOS is version P06, is there any diagnostic tools that I can run at boot up to check the system board?

First make sure you haven't installed too much memory. The computer uses DDR 2 memory but what is the maximum amount it can use. If it can only support 2mb and you have 4 installed the computer will read that as an error during boot up. Second, disconnect the Keyboard and as the computer is booting access the BIOS. disable the stop on all errors setting so it can get past not sensing the keyboard and see if that boots. If the computer boots after that the problem is a fault in your keyboard like a stuck key which will give you the constant beep. If you see the spalsh or BIOS screens then the problem is not the Video Card. If you don't get those screens double check and make sure the Video card is properly installed with nothing installed in a slot directly below it as this sometimes causes conflicts.

I still did not find beep code that match your problem..

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.


Hope this gave you an idea of your problem..

Much appreciated if you rate this help..thanks..

Different PC manufacturers have different BIOS Boot codes.

2 short = Parity circuit failure 6 beeps = Keyboard controller Gate A20 error

make sure all hardware is installed properly
retrace your connections to insure all parts
were installed correctly. you may have to disconnect and start from the
beginnig to correct this problem. disconnect all unneccesary prephrial
leave only the mouse /keyboard and monitor hooked up and try booting again . eliminate as you go to narrow down to the problem.

The beep codes below may help you identify the possible computer problems. However,
they are only for reference purposes. The situations might differ from case to case.
gAMI BIOS Beep Codes
*Computer gives 1 short beep when system boots successfully.
*Except for beep code 8, these codes are always fatal.
1 beep Refresh failure
2 beeps Parity error
3 beeps Base 64K memory failure
4 beeps Timer not operational
5 beeps Processor error
6 beeps 8042 - gate A20 failure
7 beeps Processor exception interrupt error
8 beeps Display memory read/write failure
9 beeps ROM checksum error
10 beeps CMOS shutdown register read/write error
11 beeps Cache memory bad
g 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

Any error codes?. BIOS will beep codes if it detects problems. Try removing all the periferals, incase they are screwing up the plug'N'play routines. But otherwise, I would say the MB may be toast.

Short beeps or long beeps or combination of both?

6 Beeps - Keyboard Controller Failure
Troubleshoot keyboard - unplug.

One possible problem is that your PS2 keyboard port at the back of your PC is ruined. In time, those so called "outlets" become loose specially the ones with cables which usually got pulled or tangled and make the port strained and the contacts get loose.
If that is the case, you might need to replace the keyboard port, or just stick with your usb keyboard.

1 Beep
If the PC boots properly, then this beep is normal. It is an audio cue that the PC has passed the POST and started to boot.
