Many people often try to find affordable solutions to poor performance computers. If the trouble is because of the hardware, then it has to be replaced. If something is bad with the software, then there is no need to find affordable solutions. The only solutions available are free of cost. Is your computer slow too? If you are sure that there is nothing wrong with your hardware and are seeking what could possible be wrong, then I suggest you read on.
It is true that in many cases, even if software is corrupt, professional help has to be taken and is the only way out. However, most of the cases demand attention only from the user side and along with that few clear concepts about file storage and access methods of computers. There are not many people who do not know what viruses are. Alright, not every person knows exactly what they are and how they are introduced in a computer system but still their attack can be known easily. Maybe the reason for this is because everyone installs an anti-virus program to help protect their computers. These tools can be efficient, no doubts, but are they enough? I mean what if viruses are not the sole problem with the computer?
Without going into the depths of computers, a person should know that not all viruses cause a system slowdown. They may affect its performance but only up to a certain extent. There may be problems with your registry, memory blocks or anything of that sort. If you are not fully aware of what is being discussed here, then perhaps you should seek advice from a professional or from someone who knows computers well. Do not try your hands unnecessarily. You may end up doing more damage than good.
