I had this problem last week too. It was so slow that I just gave up. That little circle in the middle of the screen just went round and round! I decided to clean up my disc. It's easy. From your START menu, Go to ACCESSORIES. Choose SYSTEM TOOLS then choose DISC CLEANUP. This will remove all the old stuff you no longer use (temporary files and other crap). When that is done restart your computer. Now go to ACCESSORIES again and choose SYSTEM TOOLS then choose DISC DEFRAGMENTAION. This will "line up" all computer files so it does not spend time searching. This may take some time to complete (Mine took three hours) but hang on in there. When completed, restart computer again. By now it should be squeaky clean and much, much faster. I thought it may be my internet connection but this solved my problems. Don't worry about deleting iles. Microsoft will not let you delete anything important, it will only list stuff you do not need or drives that can be safely defragmented. Note: set your defragmentation schedule to to carry out the procedure once per month (pick a time when the computer will be switched on). Happy youtubing!
