Some Advice Please

Iv tried re-installing FSX, Defraged my HDD, Error Checked my HDD Oh and SP1 (which i think is the problem). I still get a load of problems (too many to type right now) and my system should be able to take it (not on ultra high of course).
If this works with the screenshot it should show my main problem. When i hold my mouse over some/alot of things this happens.....
