I have an HP G6 laptop that is exhibiting a VERY unusual functionality issue -- it will not boot, to some extent. It started out as a liquid spill on the keyboard (not by me); the keyboard didn't work, but was swapped and 'seemed' fine. I booted it into the BIOS and it worked fine from there. However, upon trying to boot to the (then working) hard drive installation of windows, it will not boot. I figured maybe it had a dead hard drive, tried to swap the drive with a known good one (to test initially, further testing would have been done once the system was confirmed to boot on a known good drive; just a matter of time to install windows 7 real quick compared to a full drive test -- and I've seen clearly bad drives test good, even with a full test), and I couldn't install Windows 7. That is to say, I could get it to boot from the Windows 7 CD (Original legitimate disc), BUT only to the Windows logo screen, not to the "Install now/Repair your computer" screen. I figured I should be sure, swapped it with ANOTHER good drive. Still nothing. Tried to boot the Windows 8 disc, would only boot to the loading "Windows" thing as well. So, I figured that is a real bugger, tried to boot both with an external CD drive. Both had the same issue. Tried to boot without a hard drive, just in case something was weird with that. Still the same issue. So, I imagex'd the .wim file of a Windows 7 install, and it gave a "bootmgr missing" error. I figured maybe I did something wrong somehow since the last time I'd done that, so I popped that very same drive into a spare laptop just for fun, changing nothing else. Booted to the "setting up windows" just fine.
This is where I'm perplexed. I can let it sit on the BIOS screen for hours and it will be fine, and when it is stopped on the "Windows" logo (In windows 7 it is after the Press any key > loading bar, the 'glowing' windows orb) it is NOT frozen, just infinitely running; so I don't think that'd be a video issue. I don't understand what is going on here, I've not encountered anything like this. I've ensured all things that can be disconnected, are -- no other drives or anything like that. It just seems odd... Anyone have any ideas here?
