Sorry if we encounter sucking eggs, but...Have you tried 'cleaning' your computer and IE to try to achieve better performance? Download free CC Cleaner and this will help clean out the cr-p. Lods of software options for this. Also go through your software programmes and make sure you've not inadvertently downloaded a piece of nonsense that often gets downloaded along with other software you did want and forgot to 'untick'.

Try to download Microsoft Fixit that sort out some problems. I think Microsoft did discontinue it, but I have it and it still works 9to some extend). There are other programmes available for this too.
