Things to Maintain And Repair Computer System and Networks
1.Back up your data.
Make a full disk image immediately after reloading the OS and all your programs. This gives you a clean starting point to go back to if you need to reload everything again, and will be much faster than redoing everything manually.

2. Clean dust from your computer.

Computers are also a dust collectors. Aside from looking gross and possibly being an allergy hazard, a dusty computer will trap heat, which can reduce its performance and lifespan. The easy way to clean is by using compressed air :

1. 
   open up the case
   
2. 
   take it outside
   
3. 
   blow the dust out. The exterior of the case can be wiped down with a damp cloth. Be careful about using household cleaners, as they can easily destroy circuit boards. Computers need cleaning every day
   

3. Clean up your cabling, and everything else too.

One thing behind your computer: a mess of cables, and dust bunnies. If you’re moving your computer, take the opportunity to clean your desk and floor as well. It will certainly improve your peace of mind, and clean cabling will help prevent snags and stresses on your computer ports. If you have a lot of peripherals,
consider using cable management of some type. Twist ties work fine, or make a trip to any large office supply store.

    While you’re wiping down your desk, wipe down the monitor too. CRT screens can be cleaned with any mild glass cleaner, but LCD screens can’t tolerate it. Use a dampened cloth or a product specifically made for LCD screens.

  • 
    Keyboards can be turned upside down to dump out crumbs and dirt, or keys can be pried off and the whole assembly cleaned with compressed air.

    It is good to take a look at where your computer is located.

  Smoking will make a mess of a computer faster and there’s usually a layer of dust and tar on the circuitry that tends to be a giveaway as well.
  

4. Organize your installation disks

Keep software, peripheral, and driver disks in one place, that is close to the computer. Before attempting computer maintenance or repairs, Be sure you have them handy. it’s amazing what can become necessary in the middle of a troubleshooting session.

5. Run antivirus and spyware and scans regularly.

Computer that connect to the internet needs to have antivirus software. There is a variety of available, e.g. AVG Free to enterprise-level solutions. Use whichever you prefer. Most antivirus software will monitor the system for threats in real
time, so a full daily scan probably isn’t necessary, but do make time to run a full scan every month at the least. And some antivirus programs also protect against adware and spyware, but not all. If your computer doesn’t and if you want extra security you can have AdAware and SpyBot these two of the best known for free products available. 

6. Clean up your software.

If there is software that you don’t use any more, remove it. Be cautious, though that some system drivers appear in this list, and can cause hardware to stop working if you remove them.

7. Clean up your OS

Windows is not the most efficient operating system, it needs attention itself. Because computer saves a large amount of unnecessary information,in the form of ‘temporary’ files in which never get deleted and lists of recently performed searches, and the like. There is a program called CCleaner, which will clear out the unneeded data automatically.
8. Defragment
Once your hard drive has been cleaned up, it’s a good time to defragment. It organize your files, to faster the disk access times and improved system performance.
Steps to defrag: (Start > All Programs > Accessories > System Tools > Disk Defragmenter) works well, or there’s a list of open source and commercial defragmenting software available.
