Question about HP xw8200 PC Desktop
What does 4 blinking red lights mean on a hp d530cnt desktop mean?
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.

4x red blinking light on this system means it's "CPU thermal shutdown" this is done when the cpu fan fails to cool the cpu and the computer shuts itself down to keep you from burning up the system.
This could be caused by dirt, hair, dust in the cpu fan or heatsinc or because the fan has failed.
you can blow some canned (dry) air through the fan and heatsinc undernieth it and try to clean it. most likely you will have to take it off to clean it thoroughly or replace the fan. It is about a 15-20 dollar fan and your local computer shot or neighborhood computer guru can replace it in 10 minutes, so dont let then keep your computer longer than a day.
If your computer savy, remove the case, inspect the fan while the computers ON to see if it sounds weird or is not coming on at all. it has usually two retaing clicps the can be difficult to remove with the power supply in the way. so be ready with a philips head screwdriver and a notebook to write down anything you dont want to forget to put back. If you decide to tackle it, post again here after you check the above mentioned things and ill get you a detailed breakdown of how to do it. It real is not too hard.
