Other useful items to speed things up :
NOTE : Johnb35 is absolutely correct when he says you must do a reinstall. Reason being different mobos, different hardware, - different drivers; so you have to reinstall to get correct drivers for the hardware on your current mobo.
1) Clean any unnecessary junk off of "C".
2) Run a defrag to clean up your file organization.
3) Run "Registry First Aid" to see how many registry errors your "Windopes" install has. Sonja's laptop was running slowly and I ran an RFA check on it and it has 1407 registry errors. Wonder is, it even boots.
NOTE : RFA is a very good registry checker, it will find just about everything there is wrong in there; BUT although it is also very good at coming up with proposed solutions to any given error, (usually several for each error), DO NOT LET IT DECIDE WHAT CHANGES TO MAKE !!! Instead uncheck the fix for every error, then go through the errors one at a time yourself. If you are sure that some particular solution presented is right then checkmark that solution for repair. Otherwise leave things unchanged so as to not make things worse.
