THERE ARE TWO LED IN CABINET 

A-HDD LED

B-POWER LED

IF AFTER POWER BUTTON PRESSING NO LED GLOW CHECK SMPS

Repeating (endless loop)	Memory error	Check for improperly seated or missing memory.
1long, 3short	No video card or bad video RAM	Reseat or replace the video card.
High frequency beeeps while running	Overheated CPU	Check the CPU fan for proper operation. Check the case for proper air flow.
Repeating High/Low	CPU	Either the CPU is not seated properly or the CPU is damaged. May also be due to excess heat. Check the CPU fan or BIOS settings for proper fan speed.

  

4-CHECK KEBOARD NUMLOCK LED STATUS

IF NUM LOCK KEY IS GLOWING ON OFF AFTER PRESSING KEY THAT MEANS SIGNALS ARE COMMING FROM CPU AND PROBLEM IS IN MONITOR  VGA CABLE & DISPLAY CARD CHECK STEP BY STEP  .

 

5-HEAR BEEP SOUND COMMING FROM CPU 

1 Continuous Beep

One continuous beep isn't an officially listed Phoenix beep code but I know of several instances of this occurring. In at least one case, the solution was to reseat the CPU.

1 Long Beep, 2 Short Beeps

One long beep followed by two short beeps indicates that there has been a checksum error. This means that there is some kind of motherboard issue. Replacing the motherboard should fix this problem.

 

1-1-1-1 Beep Code Pattern

Technically, a 1-1-1-1 beep code pattern doesn't exist but I've seen it and many readers have too. Most often, it's a problem with the system memory. This Phoenix BIOS issue is usually corrected by replacing the RAM.

1-2-2-3 Beep Code Pattern

A 1-2-2-3 beep code pattern means that there has been a BIOS ROM checksum error. Literally, this would indicate an issue with the BIOS chip on the motherboard. Since replacing a BIOS chip is often not possible, this Phoenix BIOS issue is usually corrected by replacing the entire motherboard.

1-3-1-1 Beep Code Pattern

A 1-3-1-1 beep code pattern on a PhoenixBIOS system means that there has been an issue while testing the DRAM refresh. This could be a problem with the system memory, an expansion card, or the motherboard.

1-3-1-3 Beep Code Pattern

A 1-3-1-3 beep code pattern means that the 8742 keyboard controller test has failed. This usually means that there is a problem with the currently connected keyboard but it could also indicate a motherboard issue.

1-3-4-1 Beep Code Pattern

A 1-3-1-1 beep code pattern on a PhoenixBIOS system means that there is some kind of issue with the RAM. Replacing the system memory usually fixes this problem.

6-CHECK VGA CABLE

IF MONITOR SHOWING SIGNAL MESSAGE CHECK VGA CABLE.
