OK every body tunes up their PC which usually means cleaning the temporary files and de fragmenting the Hard Disk.
But there are other things to the chorus which can be done to run a system as smoothly as possible. I have compiled the following list.
Removing the system restore points, frees up memory.
Optimizing and de fragmenting the Registry.
Configuring the RAM in BIOS settings optimizes performance of PC.
Flashing the latest version of BIOS increases system stability and performance.
Updating the Motherboard Drivers to elicit maximum performance.
There are utilities like Ultra Defrag which is ultimate disk optimization.
