We are having some major problems with several of our computers.
Two different models running Windows 7: HP dc5100 and HP dx2250
They turn on, reach the "Starting Windows" splash screen, go blank and immediately restart in an endless loop.
I have tried Safe Mode with no luck. It stops at "CLASSPNP.SYS" and then restarts once again into the endless loop.
I have also tried a startup repair with the Windows 7 DVD. It is unable to do a startup repair and comes up with this error message:
Problem Event Name: StartupRepairOffline
Problem Signature 01: 6.1.7600.16385
Problem Signature 02: 6.1.7600.16385
Problem Signature 03: Unknown
Problem Signature 04: 21201148
Problem Signature 05: External Media
Problem Signature 06: 5
Problem Signature 07: 0x6b
OS Version: 6.1.7600.2.0.0.256.1
I have also seen a BSOD come up at random times right after the Windows splash screen that says "PROCESS1_INITIALIZATION_FAILED 0x0000006B (0x0, 0x0, 0x0, 0x0)." That's if i can read it fast enough before it reboots!
If ANYONE has some suggestions, please let me know! We have several computers at various locations all having the same problem! The last thing I want to do is reload all of these computers after meticulously backing up files from the hard drives!
ALSO: All of these were done with a clean install. No upgrades. Windows 7 was installed on here over a month ago with no problems until today. No additional hardware installed.
