My Computer is Too Slow

Computer working at a slow pace can cause annoyance and delay in completing our work.
Software applications that are installed in your computer are registered in the registry. In this registry is where all notes of what is happening in the computer takes place. It there are any changes in the registry, the computer functioning will be affected causing the system to operate irregularly like shutting down automatically, displaying a blue screen during start up, or freezing when you are in the middle of your work.
On uninstalling programs from your computer, the addresses are always left in the registry, as they compile up the normal function of the computer is affected.
Viruses are also big issues as far as the working speed of the computer is concerned. Viruses occupy the file space. On execution the viruses use the CPU memory causing the computer to slow down.
The hard disk can also cause the computer to perform slowly. If the hard disk happens to have mechanical problems it will be causing the computer to hang as more time is used to for the heads to read from the magnetic plates.
As technology is advancing and new software is been supplied to the market. The old systems are failing to adapt the new software. The hardware used can not support the new software. This means the old machines will have to operate on the old software which is slow and has less potential.
