Download tuneup utility.a 30 software.run 1click maintainance add still on d software main app, run registry defrag. Ccleaner is the 2nd software to try but dont miss tuneup.

@ poster
If i may ask. What is the configuration of your PC.
esp. Processor icluding (Class) and what OS r u running?

P.S i agree with specimenx about tuneup utilities. You should also try to use it to freeup disk space. Clogged up temporary folder will reduce system performance.

Cheers.

mine is slow too, cheese i feel like disposing it off

thanks everyone

i have solved the problem, it was a virus that takes up 60% of my cpu utilization that caused the problem.
i am sure this will help someone out there.

Immediately after booting, the virus assigns 60% of the cpu utilization to its self and i am left with 40% to work with and once i open more than two
applications the system will stop responding.

There are MANY reasons for computer slow downs:
not enough memory
too many programs starting up with windows at boot up time
too many junk files
too many restore points

Clean windows registry can speed up the computer.
Over time, you install new programs, uninstalled unimportant programs, update software's, install new devices,
download files from the web, etcetera, hence embarking all records in the registry system.
This is normal, but it is not wise to leave it untouched.
Once in a while, you have to check and remove files that are no longer in use to maintain the speed of your PC.
Clean registry make pc faster.
