So at work we have a computer with Windows 8.1 running on an Intel Core i5 with 4 gigs of ram. Thing is fast.
My personal PC is a 4th gen Intel Core i7. 10 gigs of ram. and it bogs down at time or feels slow doing about the same thing.
Like at work, I can start the PC cold, get to the desktop and bring up outlook or chrome and it's fast.
My PC at times feels like it takes longer. I barely have anything listed in the start up options.
I wouldn't be surprised if it's nortons doing, in 100 some days when the software expires i'll buy something else.
