How to keep your computer running smoothly (Windows). 

How to increase the longevity of your iPhone:

Tech support scams.

While it may be tempting to google up free tech support numbers the second your computer has problems to save money by way of not having to take your computer to a local repair shop, it's actually quite dangerous and can result in losing potentially thousands of dollars in garbage anti-malware programs or having your own computer compromised. 

 Pretty much any phone number on Google or random pop-up that claims to advertise tech support services is most likely either trying to sell you their garbage software products or trying to install dangerous malware onto your computer.  It's better to just take your computer to a reputable repair shop in your own community than to trust a complete stranger over the phone.
