Re: when I try to boot up lighs flash red and computer beeps

Hi:

 

There is a pattern to the beep codes.

 

Look at the table below, and you will find out what your PC is trying to tell you.

 

Chassis LED and Beep Messages

Power LED # Beeps Event

Steady green None S0 System on (normal operation)

Blinks green @ 0.5 Hz None S1 Suspend

Blinks green @ 0.5 Hz None S3 Suspend to RAM

Off (clear) None S4 Suspend to disk

Off (clear) None S5 Soft off

Blinks red 2 times @ 1 Hz [1] None Processor thermal shutdown

Blinks red 3 times @ 1 Hz [1] None Processor not seated / installed

Blinks red 4 times @ 1 Hz [1] None Power supply failure

Blinks red 5 times @ 1 Hz [1] 5 Memory error

Blinks red 6 times @ 1 Hz [1] 6 Video error

Blinks red 7 times @ 1 Hz [1] 7 PCA failure

Blinks red 8 times @ 1 Hz [1] 8 Invalid ROM checksum (error)

 

NOTE:

[1] Repeated after 2 second pause

Blinks red 5 times is a memory error.  How do I rectify the problem?

Hi:

 

Here is what I would do...

 

Turn the PC off and unplug it.  Then press the power button to drain any residual power from the motherboard.

 

1. Remove and reseat the memory module(s). Restart the PC.

 

2. If removing and reseating the memory module(s) doesn't work, if you have more than one memory module installed, remove all but one, and start the PC.

 

Test each memory module one at a time, until you find the one that is bad.

 

If none of that works, check for bulging and leaking capacitors on the motherboard. These may be particularly noticeable around the processor area.

Hello Esther31,
