How did you turn ON/OFF the second power-supply?

 

The POST (Power On Self Test) should "beep" exactly once, after a successful completion of the POST.

 

> almost boot

 

What does this mean? Any messages, when it does not boot?

Is the power cable properly connected to the disk-drive?

Is the data cable properly connected to both the motherboard and the disk-drive?

 

Power-on your computer, and launch the HP Hardware Diagnostics, to test the RAM and the disk-drive.

thank you

 

What I mean by almost boot is it would turn on for less than a second before stopping beeping then doing it all again to no avail.

As for all of the connections to motherboard etc I will check shortly.

to turn off the pc I just turned it off at the wall.

I am not sure what you mean.

 

When the computer is powered-off, and you press the ON/OFF button, what does it do in the next few seconds?

Does it show a "splash" screen?

Does it show some technical details?

Does it "beep" once? Many times? In some sort of pattern, like Beethoven's 5th (dot-dot-dot-dassssh) ?

 

After how many seconds does the Windows "splash" screen appear?

Then, what happens?
