According to The Inquirer, installing AMD's latest Radeon drivers can cause a Blue Screen of Death. On some systems - and AMD is yet to work out why, diagnostically - installing Catalyst 7.3, then rebooting, can cause a system to hit a BSOD which no amount of rebooting will get rid of. Whilst attempting to troubleshoot the problem on the DriverHeaven forums, where plenty of ATI users are queueing up to try and give their tuppence worth of technical data, ATI has released the following workaround for users who have found themselves screaming blue, as well as looking at it:

*Start the PC in Safe Mode
*Go to Start > Run
*Run Services.Msc
*Find the ATI External Event Utility Service
*Right click > Properties
*Change it to Startup Type = Disabled
*Apply, then click OK
*Reboot.

If you do that correctly, you should be able to use your computer normally. However, your system won't detect if you plug in or unplug a display whilst Windows is running, since the External Event service that you just disabled is designed to do just that.
