Follow this steps mentioned below and you will definately have a much faster and more reliable PC.
They slow your whole system down,so if you are willing to compromise,Have a basic plain one instead!
Update your hardware drivers as frequently as possible.New drivers tend to increase system speed especially in case of graphic cards,their drivers are updated by the manufacturer very frequently.
If you want to use several program at the same time then minimise those you are not using.This helps reduce the overload on RAM.
Restart only windows:
When restarting your pc,hold down shift to only restart windows rather than the whole system which will only take a fraction of the time.
If you are willing to do anything for faster performance from your PC,then try lowering your display resolution.The lower it is,the faster your PC.
Windows can be slowed down when programs run on startup.To eliminate this,check your startup folder.You can access it from the start menu:Start >Programs >startup.Another way to eliminate programs from loading even before windows actually starts is by doing the following:click on start,then Run. Type msconfig.It will take quite a long time for this program to load,but when you finally see it on your screen,explore the different tabs.They all have to do with how quickly your PC boots,so select what you want,and uncheck what you don’t want.
RAM matters :
If you have a RAM of smaller size,then you should seriously think of upgrading it.Windows run much more smoothly with Higher RAM and tends to use less hard disk space for virtual memory.
Delete temporary files:
For deleting temporary files on your system,go to Star > Run and then typetemp and hit enter.Delete all the files you find here.You can also find some more temporary files which are of no use by just typing %temp% .Delete this files too to speedup your system.
