Question Routine Maintenance & Updates

[EricLane]

I have been lazy for a while now, probably a year or two. Can someone recommend a simple, straight forward guide to what I should do in regards to updating my PC software, maintenance things? Formatting drives? Specific programs or things to update. I feel like my computer is not running so well these days and I wonder if it is my lack of maintenance.

We'd need a lot more info.

What OS?
How old is this system?
What is the full parts list?
What do you use it for?
It what way does it feel 'not running so well'?
