"This is what you do.

First go to:

My Computer>C:>Windows>Prefetch folder and delete everything in the Prefetch folder. This will not harm your computer.

(If you're not comfortable doing that, copy them to another folder you've created for safe keeping until you feel secure enough to delete that folder too.)

Then open regedit and browse to this entry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters

and to the right side double click,

Enable Prefetcher

These are the settings for making changes. It doesn't matter if it's hex or decimal.

0 no prefetch
1 applications only
2 prefetch only on boot
3 boot and apps (default)

change to 2

restart computer"
