Updating you, auggy.
The Cisco Packet Tracer app was removed for the clean boot. No crash for three days.
On August 10, 2 crashes (svchost.exe_UdkUserSvc stopped working) happened.
August 11-20, no crash.
Auguat 21, re-install Cisco Packet Tracer. One crash each on 21st and 22nd (both were PacketTracer.exe stopped working).
Unfortunately I seem not being able to provide any solid information for you to determine the cause.
