windows 7? why not first tell us the OS,
what words are in the crashed BSOD page.
let me guess, Fn+F4 and not F4
the former is turning on the external VGA jack , doing that?
i do not have enough facts presented by you to guess.
or show tests.
tell me:
1: is the RTC coin cell bad?
2: did you upgrade this from w7 to w10 with no support from HP?
3: did you test it with the bad main battery left out first, on AC power only this be like first a 5min job or less, falling off the log easy.?
4: did the external screen work, ? my guess Fn+F4
5: turn off sleep and hibernate in control panel , + power
run ok now? with all that off? be super good if yes,
now you can use it now, and later fix all the missing HP drivers later.
you know , right the driver are a 3 way match !?
match HP model.
match OS
and match the chip not working exactly
and these laptops are sold with like over 20 motherboard
different chips on them all
GPU
CPU
sound
NIC
Wifi and ill stop here there is more,, on topic of options
now I will tell you what you did wrong.
1: not asking HP for help, sorry Fixya is not HP not in the least.
2: not posting your full service tag data. so the poor help
has a clue what you bought new.
I need the 1,3,5 lines seen here.

if you upgraded your pc to a new OS, now be the time to spill those bean, no>?
sorry cant guess what you own, nor what OS is there,
not now , or ever.
here is blind easy fix.. on all HP 2006 to todays.
power on, and hammer F11 key, bingo recovery mode.
and do a full recovery. (be data backed up first) ask or search.
if that fails, the HDD is bad or corrupted or slammed by the bad guy.
