Lifespan of a CD disc

The Lifespan of a CD disc varies with the manufacturer, how it is stored and the amount of use or abuse that it has been subjected to.
Although many companies claim a 100-year lifespan, many independent tests in Europe have shown that the data stored on the CD can’t be accessed after only two years, especially the case for some low-cost choices.
One enemy is sunlight. If your CDs left on the car dashboard have stopped working after only a few years.

Jerky screens on your PC

There are several reasons why you are experiencing the jerky screen on your PC.
Check the following:

  1. Install all the Windows XP drivers for your new motherboard. Most of the motherboards come with a driver CD.
  2. Install the latest driver for your graphics card. Go to the manufacturer’s website and download ones for the exact model –-- a faulty video driver will cause the screen jerky when you scroll up and down.
  3. If you are still experiencing problems, and if your graphics card is an old one from your previous motherboard, it might be better just to replace it with a newer one, complete with new drivers.
  4. If you are upgrading from another Windows operating system like Windows 98, ME or 2000, start from scratch and install Windows XP afresh, beginning with a reformat of the hard disk drive.
  5. Finally, check whether you have correctly inserted the memory chips on the motherboards and that you are fully utilizing the total memory installed. If you have inserted say, two pieces of 256MB RAM chips, the system must report 512MB.
    Go to Start/. Settings/, Control Panel/, then click on the System Icon. Check that you have the correct amount of RAM reported in the General tab.
