STOP Messages 0x00000077 and 0x0000007A are related kernel traps that are caused when the operating system tries to load a page into memory from the paging file on the hard disk, but cannot access the page because of either a software or hardware failure.
If you experience this issue more than one time, contact your computer or hard disk vendor.
The following are all common causes of STOP Messages 0x00000077 and 0x0000007A:
•The paging file contained a bad block. •If the page file is on a SCSI device, the trap could have been caused by improper termination. •Bad cabling from hard disk to controller. •An error on the disk controller. •Running out of non-paged pool resources on the server.
Stop 0x7A is usually caused by a bad block (sector) in a paging file, a virus, a disk controller error, or failing
RAM. In rare cases, it is caused when nonpaged pool resources run out. It is also caused by defective hardware.
I would run recovery console as madmonkey sugested.
