Tom,
Beep codes tell you what is found in error at POST (Power-On Self Test).
Codes vary by BIOS provider, but usually consist of 1) some number of long
beeps followed by some number of short beeps, or 2) a number of beeps
followed by a pause, then more, etc.,
You didn't tell me the model number, and HP has used all the BIOS providers
somewhere in the thousand or so models they've manufactured over the years.
What model, how many beeps, of which type, in what sequence? (If you really
want to tackle the codes, see below.)
Otherwise, strip the maiboard bare except for the processor, note the beep
code, and then install some memory, note a _different_ code, then video if
not integrated. Once known-good memory and video are in place, you should
get a normal POST. If that doesn't do it, you're not likely to fix it.
If you do get to normal POST, then start plugging everything back in and
installing cards, one thing at a time, until you either get an error or a
normal POST. If plugging something in causes an error, it's probably
defective.

Turn on HP computer and Power light blinks while beeping sound is going
on.
Disconnected key board and mouse and powered up again with same results.
Not my computer so I know not of what OS is.
