Performance Factors

Different things can affect how a computer runs, these can be overcome depending on the situation. If your computer isn't sufficiently cooled it can overheat and crash; this can be fixed by installing more fans, lessening any over-clocking or by ensuring that the computer is clean inside as any dust may be affecting the fans.

Computer performance is seen by the amount of work it has to do compared to the time its taken. High computer performance involves a short response time for an input, you don't want it to lag and take a long time for text to appear after you've typed it. If you were a graphic designer or 3D modeller you would want your computer to render your work in a sufficient time and be successful at rendering (not crash) this could be a measure of how good your computer is. Low utilisation of resources, you don't want one program using all of the RAM or all of the CPU, this could cause the computer to run really slowly or possibly crash depending on the strain it puts on your computer.

If your computer is running slowly or there is input lag the best thing is to either upgrade your components so they are up to the task, reformat the computer to remove any unwanted clutter or viruses that could be slowing the system down or you could clean out your computer to make sure that no dust is affecting your components.
