4 beeps & 4 flashes mean problem with the power supply. For my experience, most of the time the PSU is good, it is just overloaded.

For more LED and Beep messages, check this link:

SOURCE: blinking red lights on startup

If you look up the HP diagnostic LED code on the xw8200, if the red diagnostic LED is blinking 4 times signifies a bad power supply.

SOURCE: Blinking red light at

Please take a look at this link, and consider the possibility that your power supply has failed. Also helpful may be this article. If you take it in to them, a local computer tech can load test the power supply to determine if it is in fact at fault, and they are readily replaced for minimal cost.
Most likely your hard drive will have been spared, and your data secure, but this is the reason quality surge protectors are recommended for IT systems. No way to tell for sure until you power it up again and see if the hard drive spins up...

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

SOURCE: 5 Beeps with red light.

Well those beeps tells you that something is going wrong with the hardware. Could be the memory/processor or something going bad on the motherboard. Well you could try a few things (new memory/harddrive/removing all PCI cards except the video card) to try to isolate the problem. But you probably end up at the computer store where technicians can take a look at it. So I would go there first since it's probaly gonna take some time to figure it out anyway. Also try to remove anything you installed recently. Good luck!

Computer will not start


It all depends how many beeps there were.
From http://h18000.www1.hp.com/products/quickspecs/12253_div/12253_div.HTML
Diagnostic LED Explanation Table Number of 1-second red LED blinks followed by 2-second pause, then repeats:
2-processor thermal protection activated
3-processor not installed
4-power supply failure
5-memory error
6-video error
7-PCA failure (ROM detected failure prior to video)
8-invalid ROM, bootblock recover mode

I have only really come across 4 beeps = order new Power Supply or 5 Beeps = reseat the memory and hope it works

Regards,

Oli

I have an HP Compaq dc7600 sff that will not power on. It has a solid green light on motherboard, no other response.


1) perform a powerdrain i.e. unplug the power cable from the back of the computer and then press power button and hold it down for 10 secs
2) open up the chasis and reseat the power cable i.e ATX connector coming out of the SMPS to the motherboard

Soundcard


Hey there, the HP bios is pretty smart - it should automatically detect a new sound card and switch off the internal one when installed - alternatively you can go to the 'system devices' panel and disable it in the software as well.
hope this helps
cheers
