Windows Vista BSOD STOP Error 0x0000007E

[Mr.Macroney]

I recently installed Catalyst 8.3 for x64 OS everything was fine even the Crossfire Option was already activated when I furst run catalyst, so I supposed it recognized my hardware.

I play some games for a while. But this morning when I started Vista again after loading BSoD =
STOP: 0X0000007E (0XFFFFFFFFC0000005, 0X00000000000000, 0XFFFFFA6001BD7088, 0XFFFFFA6001BD6A60)

Any suggestion beside trying to return to last good configuration, but than what?

The problem may occur when certain drivers, such as a chipset driver, are installed on the computer before you enable the BitLocker Drive Encryption feature.

With a stop giving that code, there should be a driver named at the bottom of the BSOD, right hand side, these are (unless occuring during install of Vista) always a dreaded IRQ_NOT_LESS_THAN_OR_EQUAL_TO.
Which sounds a lot worse and complicated than it is. It a driver clash, usually after you have installed a new bit of kit and \or updated a driver for something. Basically you need to either update the named driver, if it's not apparent on screen during BSOD, look up in the event log for the info. you need. Then either update or sometimes revert back to a previous driver that worked.
An easy way around these often is a recovery to an earlier date before you installed the new bit of hardware or updated the drivers\software for something.
