Illustrator cc crashes while panning or zooming

Question

So, the company that I work for recently decided to move to the brand new creative suit, but a lot of us have been having the same problem (even on MAC). After around and hour or 2 of use, illustrator (ONLY ILLUSTRATOR) crashes, I get a windows error message saying something like, “illustrator has stopped working, seconds later is closes and that’s it, if I haven’t saved anything then that’s lost. This happens at least 6 times per day sometimes more.
The thing is though, that I have noticed 2 things… when I first open illustrator, its snappy and works great, after an hour or so it gets a bit sluggish and slow (usually by then I know that it’s going to crash soon). It usually (if not all times) crashes when am zooming or panning around.
This has been happening for over a month, every day. 
Details:
Illustrator cc (updated to the latest version)
Windows 8 – 64 bits
12 gb of ram
Intel core i7-4770 3.4ghz
Anything else I should mention?
I haven’t tried anything yet, but as soon as I finish this project I’m on I’ll format the pc, and try installing illustrator again.
Any suggestions so that I don’t have to format the pc?

Answer 1

1. both tahoma and verdana are installed.
2. no plugins
3. no font managers (if thats what you mean)
4. i save my file on the main hard drive (i usualy use google drives folder so my files are allways backed up online, but the others here dont use google drive so i dont think its that)
the only common factor here i think its windows 8 and the computers we use, we all have a dell xps... something.
