I've had a looksee on the Microsnot site and have found the following, though I'm not sure they will be of much help!!:
<font color=blue>Stop 0x00000077 or KERNEL_STACK_INPAGE_ERROR
This Stop message, also known as Stop 0x77, indicates that the requested page of kernel data from the paging file could not be read into memory. Stop 0x77 can be caused by a number of problems, such as:
Bad sectors on the hard disk.
Defective or loose cabling, improper SCSI termination, or the controller not seeing the hard disk.
Another device is causing a resource conflict with the storage controller.
Failing RAM.</font color=blue>
This is the only one I found, the rest are a mystery!
Sorry I couldn't help more!
