Do remember from the past I've stipped this lappy down to bare essentials with no change:
1. internal card only
2. disabled all networking cards
3. stopped all startup programs
4. minimized processes
5. reinstalled the program
6. reinstalled vid drivers
7. played with audio settings until I"m blue in the face
8. reinstalled the OS
9. ran tests on the vid card, ram, HD processor all good
I sent you a PM BTW
