Just built a new pc. i2500k, 8 gigs on mobo, 60 gig ssd, 500 gig mechanical, Asus P8Z68-V LX, HD Radeon 6870 vid card, 27 in View Sonic LED HDMI 1080 monitor, win 7 64 bit sp1 about a month ago

Last week windows 7 crashed after it started going to blue screen, then just quit booting up. Finally had to re-install windows.

Then I had to reinstall FC2. Now I've got it working just right.
I realized that I didn't re install my Asus mobo software, Ati software, Saitek software, and a couple other programs. Plus I have not installed my video editing software. If I install them, will it change my pc so that I can't deactivate FC2 if I need to at some future point? Should I deactivate FC2, then add the software , then reactivate FC2? Do I have to Deactivate both LOMAC and FC2 or just FC2, if deactivation is required?

Again, I have this activation de activation stuff.
Thanks for your help.
