HP Pavilion DV7-4285dx
Microsoft Windows 7 (64-bit)

I made it a project to revive my son's dead laptop a couple of months ago and now I wished I had turned it in for recycling. Maybe 5 years ago my son's laptop stopped working and there was smoke coming out of the laptop. I took it apart and found that lint had clogged the fan as it was being used sitting on the carpet. I removed the motherboard, cleaned and removed all the lint and ordered a replacement motherboard and new ram and a new ac plug adapter as the old one looked burnt. I put everything together and the computer was able to boot into the BIOS. However when I try to install Windows it gets to the Windows logo and I then get BSOD and computer restarts and goes through the process again. I would say I have restarted the system 50+ times and tried various boot scenarios but they all end the same ... Windows Logo ... BSOD ... restart. I tested the hard drive and RAM and tests came back good in BIOS.  I see that on the laptop when it is on there are solid orange lights F11 and F12 light I do not know if they are trying to tell me something is wrong. The hard drive originally was empty but now I have cloned the drive from my DM4-2070US which is running the same operating system Windows 7 64-bit. I tried to bypass the installed hard drive and set up my computer to boot from a USB Hard Drive which was cloned from the DM4-2070US but I get the same result.

 

I have tried booting in different modes ... safe mode ... I have tried all the options ...

 

The replacement motherboard was "refurbished" so I don't know what refurbishment was done.

 

I have tried resetting the BIOS ... removing power cord and battery ... holding down the power button for 60 seconds, taking out the cmos battery, waiting 30 minutes and then rebooting the system. No change.

 

Any ideas or thoughts would be appreciated.
