Hello helpers,
I have a W7 Pro 64 machine (Dell). Two days ago, all programs became very sluggish/hung up, so I restarted in an attempt to set things right.
Ever since then, Windows has not booted. It goes to the Windows Recovery, but it cannot locate the Windows OS to repair/recover. Viewing the Boot Log, it hangs on CLASSPNP.SYS.
The BSOD it throws has the error message: STOP: 0x0000007B (0xFFFFF880009A9928, 0xFFFFFFFFC0000034, 0x0000000000000000, 0x0000000000000000)
These threads outline my exact problem (http://www.overclockingwiki.org/forums/showthread.php/6052-O-K-I-m-Stuck!! and http://social.technet.microsoft.com/Forums/en/w7itprogeneral/thread/b950c21f-46f4-4011-99f6-00e9c2780170). This is apparently a semi-well known issue. I found one fix that seems to work for most, which entails copying the CLASSPNP.SYS file from another system and copying it to the crippled machine (while renaming the original CLASSPNP.SYS.OLD or something along those lines). I have done this, but to no avail.
I have run all diagnostics on the drive, no errors. I've also tried changing from AHCI mode to ATA in CMOS, but again no results.
Please help if you can, I have no idea what to try next besides a clean install and I really would rather avoid that.
