Tech Myths Busted: no. 3 – You should shutdown your computer every night

Should you shutdown your PC every night?

Truth: You really should.

You will save power if you shutdown your computer at the end of the working day. It’ll also stop the fans from sucking in dust during the night.

Another advantage is that a regular reboot can resolve many computer niggles (it’s a cliche, but “have you tried turning it off and on again” – really does help).

Having said that, starting up a computer puts a lot of wear on some of the components, especially the power supply and the hard drive (unless you’ve made the switch Solid State Drives). And, leaving your computer on means it’s ready for instant use.

A good compromise may be to just set your monitors to turn off after 10 minutes, or just turn them off manually before you head home. Setting your PC to sleep or hibernate are also good options to save some power whilst keeping the computer in a state that will allow it to wake up quickly when you need to use it again.

Tech Myths Busted: no. 2 – Magnets can erase your data

Can magnets erase your data

Truth: It’s possible

Only certain types of hard drives can be affected. Solid state drives (SSD), like pendrives, are safe. Traditional hard drives, like those found in most computers are at risk, but you’d need a really big magnet. Like those used in MRI machines, for example.

For most people, there’s nothing to worry about – your data is safe.

Tech Myths Busted: no. 1 – Adding RAM makes your PC faster

Adding RAM improves performance

Can more memory really improve your computer performance?

OK, so there may be a little truth in this one. With a really old computer, adding more RAM (memory) can give it a speed boost. An increase from 1GB to 2GB will see a noticeable improvement in an ageing system.

But in a modern machine where 4GB is the norm, the benefit is much less noticeable. Increasing to 8 or 16GB will only really benefit software that can take advantage of it – gaming, or video rendering/production for example.
