I was having similar problems a few months ago.
My programs weren't running correctly, everytime I tried to go into a web site on line, my computer would either freeze, or would go to blue screen.
I have AOL for instant messages & it also gave me troubles.
After about two weeks of posting to tech forums & following every
suggestion given to me, one tech asked me if I had more than one Anti Virus program installed on my computer.
Well, of course the answer was yes. I was running McAfee as well as Norton. Even though I wasn't using the McAfee at all, it was still fighting with Norton for the Title of "King of BabyG's Virus Security".
Anyway, I uninstalled one of them, and I haven't had that type of problem since. *
Check to see that you don't have conflicting Anti Virus programs,
spyware trackers, ad-ware trackers, firewalls, pop up blockers, etc. *
If you do, at least disable one of them. *
Do a system Restore to a point before
problems started, and see if that changes anything.Just my Two Cents Worth.
Hope it helps some,BabyG
