Keeping things sweet.
Now that the computer is up and running, how do you keep it that way?
Well, the answer is a varied one. And largely depends on what you do with it.
But first we will start with the basic maintenance.
Firstly, if you have a desktop computer, I highly recommend leaving it on over night and setting your tasks to complete while the computer is not being used.
Virus scans, and disc checks can considerably reduce the computers speed. Programs updating while you are online can slow the internet connection right down.
Each program usually comes with a scheduler so these tasks can be automated.
I have mine set up thus:
3am: Windows updates
4am: Other software updates (where applicable)
5am: Virus scan
6am: Disc cleaning operations
Then the computer is ready for when you get up and check out the news.
The computer does not have to be fully logged on. Most computers can wake up from sleep or hibernate to do these tasks. Even just logging off to the log in screen is fine. Most computers can work from this state.
Doing this with a laptop is generally impractical. Your best bet is to set aside an hour or two a week to manually do these tasks.
I have mentioned before about the evil that is defrag. The process itself is fine. It's the fact that most people who are clueless about computers will suggest this first. If a computer is not working as it should, defrag will never fix that. Defrag will give you a speed boost when loading programs, but its a boost you will not notice unless you have a 3 year old computer that has never been defragged.
As such, I only reccomend a defrag once the system is freshly installed, then one after 6 months. At 12 months, I would recommend reinstalling everything. This keeps things fresh, has the added bonus of getting rid of all the files you installed and forgot about (of which you will have many) and basically make everything smooth. However, if your computer has a SSD (Solid State Drive) then NEVER use defrag. I repeat, NEVER USE DEFRAG. There will be zero benefit, but you could destroy the hard drive trying.
PEBKAC:
I hate to say it, but this is the single most common factor on computers I repair. Wether it be mechanical, or 'software failiure' the problem is usually classed as PEBKAC.
What does PEBKAC stand for I hear you ask?
Problem Exists Between Keyboard And Chair.
Problem Exists Between Keyboard And Chair.
In otherwords, you.
Now as hard as this is to understand, computer software will never go wrong. It is impossible. It is a series of instructions that a computer follows. And the computer will follow them to the letter.
It is also impossible for anyone to install software onto your computer by hacking.* You have to install the software the hacker uses. Weather you click a dodgy link, or open a dodgy email. Doing so, you cause the problem.
Mechanical failure:
This is actually quite rare really.
How many moving parts does your computer have? The fans, the CD/DVD drive, the hard drive, and that's it.
However, when the fans fail you need to stop using the computer and have the fans replaced. I would even suggest changing the fans annually to be sure. The biggest cause of mechanical failure of a computer is dust.
Once a month, open that case up, get a natural fibre brush, a can of air duster, and the vacuum hose.
Turn the vacuum on, and have someone hold the hose near where you are dusting. Use the air duster and blast everything is short sharp blasts. Back blast all the fans. If they blow out, blast in and vice versa. Make sure the CPU heat sink is completely dust free. You may need to remove the fan and the heatsink to do this. Removing the heatsink is a good idea anyway. Just be sure you have some thermal paste. Once the heat sink is removed, and stripped down and rubbed clean, run the vanes under a tap to wash them all out. Once they are dust free, run the heat sink under a very hot tap, or drop it into a saucepan of boiling water for a few seconds, then remove it. The hot water will heat up the heat sink, and all the water will evaporate. Who'd of thought the best way to dry metal would be to get it wet?
Infact, I will do a video on this very soon to show people how to dust their computers.
I'm gonna leave this here. I keep on getting distracted by kids so have probably missed loads, and not made any sense.
I will double check it later. I hope.
