Other Problems that cause a slow PC

PC Maintenance

A slow PC can have many common reasons but there can be other causes too like shorted patch cable, low memory, inaccurately set BIOS, or absence of system board drivers.

Numerous well-known problems are there which lead to a slow PC. These include low memory, a segmented hard disk, large number of active programs in the background, network congestion, inaccurately set anti-virus software and so on.

But, if an end-user has checked and sorted out such normal problems and despite that encounters a slow PC, then he should look into the following areas:

Limited patch cable

A computer that’s within a network can have low speed in case of a shorted patch cable since that creates hurdles in transmitting data to and fro.

Depending on the extent to which the patch cable is shorted and the amount of work the user conducts within the network, the slowing down of a PC gets determined. An extremely mild short mayn’t be visible devoid of test apparatus; however, too short a patch cable can desperately give a slow PC. Apparently, a user notices the shorted cable whilst uploading software from an Internet server within the network.

Low memory

Whenever a computer is with low memory, Microsoft’s Windows uses a technique known as paging with which an amount of memory in a page that’s presently unused is moved out of physical RAM onto virtual memory or swap file. This memory page remains inside the swap folder till the time it’s required when it’s shifted again to the RAM.

However, all pages of memory cannot be swapped. A few, which have critical data of the operating system, have to constantly remain inside RAM. Similarly, when the process of swapping occurs, a part of RAM is used up. This therefore, implies that during any point of time, the memory obtainable for use is less compared to what one may expect. While there’s nothing unusual about swapping, if it’s done excessively, a process named thrashing, it can cause a severe hazard. Thrashing takes place whilst data is continuously transferred across virtual memory and RAM. Thrashing is most obvious when the computer operates extremely slowly as also its hard disk runs uninterrupted. So to do away with a slow PC as in the current instance, the most suitable method is to increase the system’s memory.

Inaccurately configured BIOS

The BIOS (Basic Input-Output System) forms a very important part of a computer and it’s kept inside the motherboard’s chip. Moreover, it helps the computer’s OS in communicating with the hardware. So if it’s incorrectly configured, it can bring down the speed of the computer by a good 40% thereby creating a slow PC. Sadly, with new motherboard chips and processors finding release, options in BIOS keep on getting more complex.

General drivers for system boards

Most computers have drivers by default that their system boards utilize. Such drivers are specific to system boards or are tailored for the hard disk operator. For a branded computer like Gateway or Dell, its drivers are present by default. But, in case the computer is of a generic make, alternatively, Windows had been installed later, then the driver possibly was never there; consequently, an error may happen resulting in a slow PC.
