I received an HP Envy 15 1050nr that had overheated and stopped booting. I figured out that the hard drive had some bad blocks, and I replaced it. I was able to re-install Win7 on the new drive and boot all the way. So far, no problems.
Then, when I installed the 120 automatic updates to windows, upon restarting, it runs for about a minute or two, then freezes. I reboot, and it won't boot all the way. If I wait for a long time before rebooting again, it will boot all the way, run for a minute or two, then freeze. I often hear an audible click from inside the laptop right when it freezes. This problem seems to be linked to the windows updates, but there are so many, I have no idea. Any ideas? Thank you so much!
