My daughter’s HP Pavilion dv6 was getting a System Fan (90B) error, so I replaced the fan/heat sink assembly following the Maintenance and Service Guide. I am now getting a Hard Disk 1 error (3F1). Running the advanced system diagnostics passes all tests on the hard disk, Smart Check, Short DST, Long DST all pass. So I ran the system recovery , F11 from the startup menu and Windows 7 boots up normally!? I also ran chkdsk via the recovery cd and there are no errors found. Any suggestions? thanks

Enter BIOS by F10 key. Once in tap F9 to load Default settings. Save & Exit.
If no joy-try reseating the hdd. You may have slightly loosened the connection while working on the fan assembly.

Thanks for the quick reply, Unfortunately resetting to default settings did not help. I also reseated the HD connection with no luck. I am wondering whether the boot manager may be corrupt. I do have a Win 7 PE disk.

So when I run the memory test from the boot diagnostics (F2) it is showing a memory error. It appears the 4g simm may be bad, 2g simm passes. If I hit esc key (pause startup) immediately after power on and then (F11) - System Recovery from the Startup Menu Windows starts up fine. BTW I am running Win7 64 bit Home Edition. It appears the HD is fine.
