Now, if you're really into Conpiracies, you'll find that there's a second set of hidden Cache.

You can also do a Windows Dsik Cleanup to speed things up a bit. www.optimizingpc.com...
Also take a look at your right hand corner and remove unnecessary background programs and processes, like Quicktime, etc.
You can also speed up your start-up by deleting the preload/prefetch files.
1. Browse to C:\windows\Prefetch.
2. Delete all files (or at least all those older than say 2 or 3 weeks) except Layout.ini
You can also turn prefetch off. Prefetch is designed to speed up program launching by preloading programs into memory - not a good idea is memory is
in short supply, as it can make programs hang. To disable prefetch:
1. Click 'Start' then 'Run'
2. Type in 'Regedit' then click 'Ok'
3. Navigate to 'HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters\'
4. Right-click on "EnablePrefetcher" and set the value to '0'
You may also want to run RegClean (Download here
If you still battle with low speeds, you may want to consider a drive format or a hardware upgrade (RAM or Harddrive space). ONLY as a last resort!
Hope that helps.
