Hey DanTD,

If you're having issues with "overcrowding", there's a good chance you're also having issues with virtual memory space. Windows recommends that you have at least 20% of your hard drive free for optimal performance. If you are under this, Windows may be having issues maintaining an adequate swap file.

Have you tried running registry cleaners or sweeper programs to get rid of old/outdated programs that are installed? You may be surprised at the amount of space you can get rid of by removing old programs you no longer use.

I'd also recommend running a disk defragmentation program (Windows has one - albeit one that is not as optimated as others). This can speed up your PC by making sure files are in one piece rather than fragmented all across your hard drive.

If you are able to safely remove enough old programs to upgrade to IE9, or download a different, more compatible browser (IE9 is still quite behind-the-times compared to Chrome or Firefox), you may see quite a difference in your PC's performance.
