TEN USEFUL PREVENTIVE MEASURES FOR MAINTAINING YOUR SYSTEM
One sure way of getting value from your computer equipment is by taking preventive measures. Here is a list of 10 such useful measures. Note that some of these measures can only be carried out a service engineer.
1. Files Backup
Files backups are very important for all types of PC user. By creating a copy of your files, you can restore and continue working in the event of disaster.
2. Clean the Mouse
Like the keyboard, mouse is susceptible to dust and debris, which are contacted from the mouse pad up to the mouse ball and roller. Dry the mouse thoroughly and use a clean cloth, dampened with ammonia / mentholated spirit.
3. Clean the Floppy Drive
Clean the drive with a disk cleaner.
4. Check Memory (ONLY TO BE CARRIED OUT BY A SERVICE ENGINEER)
Loose memory can cause serious startup problem for the PC.
5. Check the CPU (ONLY TO BE CARRIED OUT BY A SERVICE ENGINEER)
The CPU is the single largest IC on the motherboard. Examine the CPU to see if it is evenly inserted in its socket/slot. Also check the CPU fan / heat sink for proper cooling.
6. Update the Boot Disk
Your PC should always have a boot disk, which can start the system from a floppy in the event of an emergency system failure. Basically for most Operating systems-Win95/98/2000 etc. use this procedure to create startup disk
*Label a blank formatted floppy diskette and insert it in your floppy Drive
*Click start, Settings, Control Panel
*Double Click Add/Remove Programs icon
*Select Startup Disk Tab
*Click Create Disk
*The utility will remind you to insert your diskette
7. Blow the Printer
Unplug the printer for 10 to 15 minutes allowing the capacitor to completely discharge, blow the printer to remove dust and particles that often cause paper jam.
8. Clean the CD Lens
As the floppy/hard disk drives read/write head contact dust CD lens is not excluded. Use CD lens cleaner
9. Run Scandisk
The Scandisk utility is designed to check your drives for file problems. It also marks any bad sector and copy files to a good sector during the operation
A:\> Scandisk
From Windows:
* Click Start, Run,
* Type Scandisk
10. Update Anti-virus Software
Precisely, new viruses are created nearly every week. For efficient virus protection the Anti-virus software needs to be updated on a regular basis

The Ten Immutable Laws of Security
Law #1: If a bad guy can persuade you to run his program on your computer, it's not your computer anymore.
Law #2: If a bad guy can alter the operating system on your computer, it's not your computer anymore.
Law #3: If a bad guy has unrestricted physical access to your computer, it's not your computer anymore.
Law #4: If you allow a bad guy to upload programs to your web site, it's not your web site any more.
Law #5: Weak passwords trump strong security.
Law #6: A machine is only as secure as the administrator is trustworthy.
Law #7: Encrypted data is only as secure as the decryption key.
Law #8: An out of date virus scanner is only marginally better than no virus scanner at all.
Law #9: Absolute anonymity isn't practical, in real life or on the web.
Law #10: Technology is not a panacea.
These are the 10 immutable laws of security, developed by the Microsoft Security Response Center, based on thousands of security reports that are investigated every year.

DISRUPT THE STATUS QUO!

     
1.

Ideas are not enough. You must be action oriented to improve your future.

 

 
2.

Don't just think but act. You get results not only from thinking but from acting.

 

 
3.

You have ideas. You want to achieve. You want opportunity.

 

 
4.

But what are you still doing in your comfort zone? The comfort zone is a dangerous place.

 

 
5.

"I wanted to", "I was going to" cannot put on a light bulb, not to talk of moving you forward.

 

 
6.

Aren't you tired of hoping and criticizing? Stop defending status quo that locks you down.

 

 
7.

GO on the offensive now with your Cisco Internetwork PLUS.

 

 
8.

What is the use of ideas without action?

 

 
9.

Start becoming the achiever you deserve to be.

 

 
10.

MAKE SURE THERE IS NO STANDING ROOM FOR EXCUSES.
