Windows 7: IE9 Freezing up, cant type weird stuff

Ive had this problem on two or 3 diffrent O/S installs on my PC
The Problem:
Some days i will for instance be typing an email in my yahoo email or on a fourm site and typing but nothings showing up until i scroll the page some then it shows up but is ehhh well i guess sticky would be the word and things just act or seem weird, i keep thinking someones hacking me so.
What ive done and checked:
No Malware i run a registered version of Malware bytes, NIS, CCleaner, tune up utillities and i keep an eye on my network activity as well as sometimes leave my task manager open and watch for any new processes or anything that might be clogging me up. i dont run any toolbars except the NIS one and ive checked everything with hijack this as well and no issues.
What ive accepted:
This is IE9 right?

So i guess i am the only one with this issue???
Still does it, did it a few times today, the browser pretty much freezes up and stutters as if something in the background is hogging all the resources but i do not have anything doing that, Then when i type its not showing up, i cant type for ten mins and see nothing untill i scroll the window a bit then it all the sudden shows up. hmmmmmmm! Well thanks for all the help guys! Ha!
EDIT: I just changed back to using GPU rendering instead of software rendering, i'll see if that helps any
