STOP 0x7F (UNEXPECTED_KERNEL_MODE_TRAP)

STOP 0x7F indicates if the system has ZoneAlarm installed - it is a known cause of BSOD with Windows 7. You may want to try this two options before you start removing ZoneAlarm.

1. Try these 4 Microsoft HotFix...
Microsoft has released 4 Microsoft HotFixes. These 4 Hotfix which I can neither verify or discount. It may work, it may not. (One is required after installing SP1 which is below how to install SP1.)

2. Upgrade to SP1 and this HotFix
SP1 provides bug fixes, improvements, new features, enhancements and much more. If you wish to upgrade to SP1, use Windows Update or use Microsoft Download Center if you are installing SP1 on more then one computer

Then try this HotFix....

If those 2 steps still cause BSOD - then it is best to remove ZoneAlarm completely. Then use a different anti-virus/firewall software.
