Good morning,

yesterday I changed the power pack of my desktop HP 8300 with a new one.

the computer has been disconnected from a week from the power supply (230Vac).

Now it doesn't work when I press the start button. No noise, no led blinking on the front side.

On the motherboard there is a green led blinking (near the led there are 2 word: AUX and CATERR#).

I tried to change the power supply cable. No change.

I tried to remove RAM. No change.

I read others post on this forum.

Please solve my issue.

Thank you
