here are some helpful tips to keeping your pc running smoothly
everyday:

-Check for virus/spyware definitions: viruses spread within hours so keeping your antivirus/spyware software up to date is crucial.
-Backup critical data:Make sure that when you get some data that is very important you back it up in case of a system failure.
Every week:

-Search for spyware/adwarepyware and adware can slow down your pc by taking up space or it can annoy you by constantly having ads pop up onto your desktop. The tools I reccomend are spybot search and destroy and ad-aware.

-Check windows update: To make sure your system is in the best condition you should use the windows update to scan for microsoft software and hardware driver updates.

Every Month:

-Check for software updates: make sure you have the most up to date software on your system so that your software performs at its best.

-Create restore point: Creating restore points for your system is always a good idea because sometimes you never know when something is going to go wrong.

Every Year:

-Cleaning your system:
-Clean the inside of your pc very carefully to make sure that no dust is clogging fans or anything like that.
-uninstall old or useless programs that you dont want or need anymore so that you create space on your computer for better stuff or whatever
-Delete your old registry files: after you uninstall software a registry key is still left behind so you want to get rid of those so that they dont conflict with new registry files. Goto start<run<regedt32 then expand the folders HKEY_CURRENT_USER and HKEY_LOCAL_MACHINE and expand the subfolder software then scroll down the list and delete any registry keys for programs that you have uninstalled (be carefull while doing this and if you downloaded a trial then bought the serial make sure you that you arent going to get that app again or that you have the serial somewhere).
