Hey everyone,

I recently installed Norton antivirus (came with a trial for 60 days with my mobo, never tried it out until I got my SSD), its very nice, considering getting it for another year unless I can be proved wrong.

Anyway Norton informed me while I was playing BF4 online that one of my CPU cores is at 100% usage, this was a bit of a concern, I am playing BF4 at ultra settings with v-sync on, although it did not effect the PC performance, everything was running smoothly, I was still getting 70 - 80 FPS and no lag. Should I be worried that my CPU is going to be burned out? Or is it OK for 1 core to run at 100% load?

My setup is:

intel i5 2400 sandybridge @ 3.1 GHZ, turbo boost it to 3.3 GHZ on all 4 cores
Asrock Z77 Fatal1ty motherboard
Asus GTX 770 2GB 256 bit O/C edition
Kingston 16GB RAM
Samsung 840 EVO 250GB SSD for my operating system
1TB HDD for storage
Windows 7 pro sp1 64 bit
LG 1600 X 900 display

Thanks in advance for any reply's
