A lot of Junk file, virus or out dated software can cause the problem,if you are sure, the Pc is free of the above.l will suggest, downloading an up to date browser version (Opera) preferable to enjoy a speedy service on the internet

Maybe your computer have been overlasted by much amounts of documents and emails. You need to delete what you don't need. Delete your temps and cookies.

There might be a numerous of files that's need to be deleted in your PC. Also, viruses might even slow the processing in your computer. You need to clean your PC of viruses and check those files who and free your disk from unused stuffs. This might solve the problem.

I suggest running a software called CCleaner. Its a free easy to use computer cleaner. I run it once a week and my computer runs very fast. (ccleaner.com).

The cause why our pc experiencing slow down is due to virus. So if this is happening i will start a full scan in my system. If no good result, i have no choice but to reformat it.

It is possible that you have stored too much datas on it. Check your hard disk drives and delete what you are not needing anymore.
