the only way to get help is to
look at the service tag , see that? all HP have them.
and has a real and full model number.
DV7, come in vast flavores, even different countries. (laws very by that) , if it ends in 'US" its usa model.
no photos of jumper stated you touched the only CMOS fidding you can do (hardware) is to remove the coin cell.
and put it back after testing it for 3vdc. below 2.9v I trash them.
So you turn on the power.
and it does what.
screen never gets BIOS prompts? works in white, like (push esc key for bios)
is the esc key dead , at power button on, you press it.?
does the PC fans work?
P7-1000 is a series of PCs not just one. year 2011 is my guess on date, not too old
lets talk , shut downs. has lots of causes,
but in macro form its:
A: bad hardware
B: Windows, is confused. ( easy as falling off a horse)
A: hardware.!
1: this PC has a PSU, and if it seens errors on the power supply output LINES, 5 to 10 of them , it shuts down automatically, to save blowing up say a $100 processor chip , Or lots more....
2: the PC can also shut down for CPU overheated, in seconds, or can take hours if said PC is dust/lent jam packed up.
never seen PC run over a year and not packup. ( I service mine every year) or bad fans, mine has 3. all 3 must work.
3: there can be other causes hardware to cause this and is found by a qualified tech, this, (read lots of testing)
SOftware caused.
THE PC SOFTWARE can in fact send a SOFTPOWER OFF command to hardware, or go to hibernate or sleep.
I'd boot the PC to Live LINUX or LIVE WINDOWS PE disk or stick, run now ok, if YES, the problem is WINDOZ (yours on that HDD of yours)
wow over 7 different motorboards on P7's series used, and is YOUR QUESTION. and matters.
here is the HP list of 1000 series PC
huge list. which one IS YOURS? i cant even count that high, at my age.

if you PC fails to boot, tell is here, with all symptoms do not pull any MOBO cables or jumpers, first. ever.
At boot is the screen totally dead 100% or what?
Does it reach windows login screen even for 1 second?
are the fans dead.
Example1: (generic)
the Chicago MOBO (1 of 7,my roll of dice and a wild guess) has this, jumper set.
again just 1 guess on what you have, this is and example only (generic)
if the coil cell is still good, at 3vdc, and if someone played with BIOS and messed it up , one can do this
one can, move the jumper from normal (default means NORMAL) to Clear, count to 5 and put it back
do not put it back wrong, or bad happens.
By default the CMOS will boot do drive 0. (first drive in system port 0) what we call the C: boot drive.
if the boot drive fails, then do a F11 restore.
if the HDD can not be heard to spin its dead or cables fell off.
F11 will fail, (HP magic restore) on all HDD that fail, because that is where it lives.
So you are using BIOS passwords???? if NOT, this will CMOS never cure a windows PW nor will it clear a Microsoft PW
Most modern HP BIOS passwords , take special help from HP to clear, something I can't do.
