Problem with PSHED.dll; unable to bootup Win7 Ent. x64

Situation: The plant had it's post-holiday break start-up this am and one of the PC's went into Startup Repair mode. I was called in and found that the file "PSHED.dll was corrupt." After ~6 hours, I am unable to boot the PC. The PC is a HP desktop with 4 GB RAM, only a year or so old. Runs Win7 Enterprise x64; the load on it is relatively light. (I work as an on-site IT Support guy, Tier-2.)
What I've done:
- Tried to boot to Safe Mode - no luck.
- Restore to previous point in time - no luck.
- Tried the steps in How to Recover from an Infinitely Looping Startup Reapir Loop without Reinstalling Windows - no luck.
- Tried the steps in Windows Vista Boots to a Black Screen with only the Mouse Cursor - no luck.
- From Cmd prompt within WinRE, ran bootrec.exe /fixmbr, and bootrec.exe /rebuildbcd - no luck.
- Created a System Repair CD on my laptop and booted to it - no luck doing all the above.
- Over-wrote the corrupt PSHED.dll with a copy from my laptop and rebooted - no luck.
About half the time on boot-up from the CD I can "find" an OS, other times not. When the OS is found in WinRE, I can get to the drives and folders, so could pull off the user data, but I'd like to repair the PC if possible - better chance of learning from the experience. My limiting factor is the entire plant startsd up tomorrow monring at 6 am and I need to have this on-line by 11 am that same day - allowing time to reimage it and transfer over the user data.
Question: Is there anything else I can try? (We don't have the install media; we just download the images as needed.)

Hi Mike,
The file PSHED.DLL is part of the component that enables hardware errors to be generated.So, please check whether this issue still occurred after changing the HDD.
Thanks,
