clicking on settings or history loads for a really long time if it loads at all.

I even tried to disable my overclock

Hello,

one day Opera started freezing (not responding) for 2-3 min every time I did some "more demanding" things in it, like loading multiple Pages.
When it freezes it does so for about 5 to sometimes 10 min and if I force close it, it takes about as long to start it again.

I tried:
-reinstalling
-clearing browser data
-reinstalling
-completely deleting every folder with Opera in its name and then uninstalling and installing it again
-try the beta

After a restart Opera starts like normal but then does the same thing as above.
I'd really appreciate help I really like Opera and I already sunk multiply hours into this problem.
