BSOD or blank screen

I have a Pavilion dv5 - 1217AX with Windows 8 operating system. It was
upgraded from Vista to windows 8 last year and it worked really very well for
about 1 year. Here are the issues I am facing these days

1. When powered on - Caps lock and Num lock LEDs keep flashing twice and the
sequence keeps repeating - I checked the error code on some forums and it
sounded like BIOS issue so I flashed the BIOS F38 again (SP46501) but it didn't
help. I also thought it could be a memory issue so I removed the memory module
and cleaned the slots and fixed the modules again but no luck. I also tried
running the laptop using only one module, tried both the modules one by but no
changes in error code. Then I thought it could be a toy battery issue so
replaced the toy batter that fits on the motherboard but no luck. I have also
tried booting up removing the laptop battery pack but no luck.



So how does it boot now? - Once powered on I keep getting Caps lock Num lock
LED flashing issues every time. Then I power off using power on/off button on
laptop around 15 times or more then the laptop somehow boots up. There is no
fixed pattern, sometimes it boots after 15 attempts, sometimes 50 attempts.



What happens after booting? - Sometimes the screen goes completely blank
without any error message on the screen. Sometimes Windows 8 crashes and laptop
restarts, when it restarts I never see LED flashing issues (surprising). It
crashes when I am watching some videos or playing some games, so looks like ATI
Radeon driver issue (driver is 8.970.100.7000 for HD 3400 display card).

Let me know if there are any suggestion to fix the booting and crashing
issues faced.

I have attached logs

You're having worst type there is: 0x124 hardware hal stops. Sometimes it is still caused by drivers but some hardware in the machine might be defective or RAM set unwell.

These drivers need to be updated or removed:

Uninstall Norton then use the removal tool for it too. Set Windows Firewall and Windows Defender to Automatic and start them too, using services.msc.

Uninstall VMWare or similar.

Update motherboard bios version to latest.

The machine most likely is going to easily be fixed once you're able to manage to update or remove all of them.

If you can't figure it out and all that stuff, then clean install Windows 7 with a format.

Best of luck with it and enjoy.
