Why A Computer Becomes Slow?

With the advancement and continuous changes in the IT and computer technology the processing speed and performance has certainly increased and it is meeting todays requirement where speed is really matters else there are many tasks they cannot be performed unless speed is up to mark and if there is any Slow PC issue it is really not possible to complete many important tasks that are related to online applications. Like online reservations, share trading, railway and air ticket booking and many others.

It is seen that in spite of best hardware specifications a Slow PC issue can be found and it severely affects several other activities in the PC. It is possible that in the beginning the PC will work at its best due to no infections, no hardware or software fault, however as time elapses it becomes slower and sometime goes beyond it and freezing and automatic shut down issue may also find. Also come what may as the time passes the speed really reduce and PC becomes slow. Thus to use Pc at its optimum we need to keep it checking on and try to apply standard PC optimizing activities so that it can perform with its best always and in turn we also get our best. I would like to discuss few basic and main reasons behind why does a slow PC issue occur or why does speed of a computer system decreases as it grows older.

Why a computer becomes slow/why does a slow PC issue occur?
A straight forward answer for this question that why does a slow pc issue occur is there is not a single reason behind it ( though certainly it is possible that very few times a single reason may cause a pc slower like a hardware issue e.g. faulty RAM or bad or corrupt driver etc). The basic cause behind the slow PC is bunch of issues within the computer and just removing one cannot resolve the issue. So always be aware of this fact that number issues might be several behind a slow PC.

1.Any hardware fault. Remember always there is no alternate for any hardware issue or component; this is basic requirement that a hardware specification should be up to date and must be meeting with the programs running in the PC. Else no program can run or it malfunctions.
2.Virus or malware or any such malicious programs infection like Trojan horse etc in the PC.
3.Corrupt registry due to the same malicious or damaged programs.
4.Any software removal entries left in the PC can create slow PC issue many times.
5.Dump files, temporary and unused files, if they are very huge in size. I have seen in a PC there was 35GB of temp files and it showed C drive is full, so cleansing of these temporary files are needed after a certain interval.
6.If any obsolete program in the PC.
7.Corrupt and damaged or incorrect driver set is installed in the PC may cause not only slow PC issue but also creates system freezing and serious issues like BSOD.
If above mentioned steps are ok I personally think the chances of being a PC slow are very less.
