Hi

Blinking lights can point to the problem area

EG:

LED and BEEP condition	Description	Corrective action
Power button LED blinks 5 times with 5 beeps	Memory	Reseat memory DIMM modules. If the problem is not resolved, contact support to resolve a possible RAM or Main-Board failure.
Power button LED blinks 6 times with 6 beeps	Video Card or Graphics	Reset the graphics card (if applicable). If the problem is not resolved, remove other accessory cards, and replace the graphics card or Main-Board.

Hi

Well if you read the document it says...

Blink error code sequences continue until you unplug the computer or press the power button.

and that may well be what you are experiencing.

If you described the sequence better, Number of times etc then perhaps I can match to a fault,

ELSE

First:- Turn off the computer, press and hold the PWR button for 4 seconds.

Then - Leave only keyboard and mouse connected, disconnect all externally connected
devices such as Docking Station, USB storage devices, displays, and printers.
Unplug the AC adapter from the computer.

Next - Press and Hold the Power button for 15 seconds to Hard Reset.
Rinse and Repeat

AND/OR - Power on your PC, press Esc (repeatedly), then F2 at the prompt.
Choose System Tests (Fast Test does a 4 minute hardware check).
AND/OR
HOW DO I USE DIAGNOSTICS?

HP PC Hardware Diagnostics Windows is a Windows-based utility that allows you to run diagnostic tests to determine if the computer hardware is functioning properly. The tool runs within the Windows operating system in order to diagnose hardware failures. HP PC Hardware Diagnostics Windows comes pre-installed on new HP computers, but if not on yours, download here:- http://ftp.hp.com/pub/softpaq/sp93001-93500/sp93457.exe

Hi

If holding down the power button does not switch off the PC, or start any kind of screen, then I suggest you get a Local PC shop to attend to it.
