Need some more information to help. The blinking should be in a pattern. I.E. blnks 3 times...pause.. blinks twice... pause and repeats etc... The blinking LED's are an error code that can be taced to the issue. Please provide more information to better be able to find you issue.

Thank you so much for trying to help us...

 

It seems to be just one blink then a pause, then one blink - pause.

 

Blink seems to last about a 1/2 a second and the pause seems to last about 2 seconds.

Accourding to HP error codes that code means the CPU has failed. Whereas this is possible, I would test a few things before tossing the computer out. First, I would strip everything out of the system (hard drive, optical drive, any external devices, and RAM) then reboot the system and see if the error is still there. You may got other errors because of the missing items buut dont concern yourself with that. If the one blink goes away then the CPU is fine. Reassemble the computer starting with the ram and test as you put each item back in until the issue comes back. Minor things such as a faulty USB port can cause issues in a computer. As an Example:

 

A while ago My house was hit by a power spike afterwards my system wouldnt start at all. After disconnecting everything it would start up. As I replaced one item at a time it turned out the spike shorted out my front USB ports preventing my system from starting. I left them unplugged and the system has been fine ever since.
