Can't start XP. First error message is: "Winlogon.exe entry point not found. The procedure entry point AssocGetPerceivedType could not be located in dynamic link library SHLWAPI.dll."

If I click thru that I get second error message: "User Interface Failure == the logon user interface DLL msgina.dll failed to load, contact your system administrator to replace the DLL or restore the original DLL. RESTART."

I dont have a system admin, this is a home PC.

If I restart it takes me back to the first error, Winlogon.exe entry point not found. Endless loop between the two errors.

Anyone know what this means? Or how to fix??

Many thanks,

Bootup failure can be due to a variety of issues to include application faults, hardware failures, or malware. Startup failures that occur before the OS loader (Ntldr) starts could indicate missing or deleted files, or damage to the hard disk master boot record (MBR), partition table, or boot sector. If a problem occurs during startup, the system might have incompatible software or drivers, incompatible or improperly configured hardware, or corrupted system files.

If Windows XP (or 2000) refuses to start in normal mode, press F8 repeatedly right after you turn on your PC but before the Windows log-on appears and select "Last Known Good Configuration" or System Restore from a command prompt in Safe Mode to return to a previous state before your problems began.

If, that does not work then see:
