Virus Protection.The number one reason I see computers come into my shop is for Virus Removal.If you are connected to the internet, you need virus protection. AVS (Anti Virus Systems) have just become one of those necessary things you need to have in order to be able to operate effeciently. What makes things worse, is that you can't depend on them 100% - the virus writers are constantly trying to find ways around them, so you also have to use some common sense. Don't open attachment from people you don't know. Don't click on links that are "shortened". If you get a pop-up, don't stop to read it, close it.All of these things will help you keep you computer clean of bugs and out of my shop. Backup, backup, backupI just can't say this enough. Any data you cannot afford to lose should be on at least two separate physical drives. I personally highly recommend the "cloud" solutions. My company is working with an outside vendor to provide secure, encrypted backup for your personal files ($10/month for the first 25G of storage), but if not us, consider a service like Mozy or Carbonite. It's fast,automaticand you don't have to think about it.Otherwise, CD/DVD or external harddrives would be my recommendation. I don't recommend flash drives (memory sticks) simply because of how easily they are lost and the failure rate they have. The problem with these methods is that you have to establish the habit of updating your backups, and then stick to it! Having a six-month old backup is better than nothing ... but not a lot.If you don't have a backup system in place NOW, then you need to take action. Drive SpaceDo keep at least 30% of your C: drive free for Windows to use. Once your get over the 70% mark on your hard drive, the system starts having to work harder, which results in your system getting slower. The fuller your drive gets, the more that overhead will affect your system performance.The good news is that you don't need a new computer! Just a new hard drive. :) Power ProtectionI highly recommend that you purchase a Surge Protector or UPS for your computer equipment. One of the common hardware repairs I see is power supply replacement, where the power supply for your computer is acting as a fuse to protect the rest of the computer from a spike coming through the power lines ... and fuses, as you may know, only work once.Then you replace them.A UPS (uninteruptable power supply) will keep your computer from crashing during power outages, and will protect your computer from low and high voltage occurrences. An UPS is far superior to a surge protector and will save your computer from almost any type of power disaster. (See #1 above for what happens when your computer crashes.)This is what I recommend for my business customers and prices on these devices have fallen to the point where they really should be part of your home computer equipment as well.Keep in mind that the battery in a UPS will eventually fail, so you will have to replace them every couple of years. And the ability for any device, UPS or simple surge protector, to shield you from power spikes does degrade over time - so even if you don't get the UPS, you should replace your surge protector every few years as well. Shut your system down properlyYes, someones it's faster to just pull the plug or hold the power button down until the computer blinks off... but every time you are doing that, you are roling the dice. If at all possible, only turn your computer off with the power switch until Windows has shut down.The one exception to this rule is when your computer locks up and your hard drive is not running (hard drive light is not blinking). In this situation, you can turn the power off without harmful effects to the hard drive. As cutting the power can also result in lost data or Windows files, you should only do this when you have to.Following this rule will prevent permanent hard drive defects caused by the hard drive heads contacting the surface of the drive disc, and it will prevent a host of Windows problems.Whenever possible, recover from crashes by pressing the Ctrl + Alt + Delete keys at the same time. Press them again to reboot your computer. Startup ProgramsDo not let a lot of programs load up when you start your computer. They use valuable memory and Windows Resources (Windows internal workspace).All programs in your Windows System Tray (in the lower left of your screen) are running on your computer. Close them if you don't need them or run them and configure them not to load when you boot up.Other programs running in the background can be found by pressing Ctrl + Alt + Delete at the same time. Clean your computerOnce or twice a year, more often if you have a dusty environment, invest in a can of compressed air, pop your system open and blow it out. Pay special attention to any heat sinks (Processor and GPU spring to mind) and to the power supply. Keep the nozzle at least two inches from what you are targeting and, more importantly, DON'T LET THE NOZZLE TOUCH ANY COMPONENTS!Static, you see ... Keep your disks.Keep track of the software disks you receive with your computer and new peripherals. These disks contain valuable software drivers and programs for Windows and are needed when Windows must be reloaded. Keep these disks and your Windows software disks in a safe, dry, place -- you never know when you will need them.
