The most common fault of HP DV7s that the GPU soldering on the motherboard is faulty...there was a class action lawsuit for that issue that ended long ago. It's partly due to the switch to lead-free solder a few years back.
Companies will perform what is called a GPU reflow procedure for that mobo for $40 USD (must send them motherboard).
If you're handy you can do the reflow yourself with a toaster-over or a heat gun, as there are YouTube videos about that. I have personally fixed two of these machines with a heat gun.
If the PC won't boot, then removing the drive is the only option
