I am facing this problem for the first time! I have this HP dv6 2180ek which is my friend's. It had a faulty HDD (startup repair loop even after formatting it) I replaced it and by the same occasion I re-applied the thermal paste.
Now comes the software part. The DVD drive is not working so I copied the windows 7 x64 dvd to a USB flashdrive and booted from it, but it would get stuck after loading the files (while the orbs are forming) and it would just sit there. I said maybe the new HDD is also faulty so I tried another one: same result. I even had another HDD with working a vista installation in it and it would not boot in freezes just before the "welcome" screen.
Then I said maybe the flashdrive is not working properly so I looked around and found a DVD drive lying around so I hooked it up. I tried to install from the windows 7 dvd, this time it gets a bit further (the orbs form) and just sits there again.
I have an old XP x86 CD so I tried with that: it would get to the blue screen then baaam a BSOD (scan your pc for virus or something)
I thought maybe I could change the HDD mode in the bios. The PC comes with InsydeH20 rev 3.5 it has nothing at all just an info screen, an error log, an HDD test, a RAM test and restore to defaults! I did run both tests more than once it says everything is ok.
I am getting puzzeled here! I could not find an update or a mod for the bios to access functions.
Thanks in advance for your valuable help
