Make sure you back up anything you want to save videos music pics etc. you will lose every thing doing a clean install make sure you have all your drivers from maker of your computer that will make install easier hope this helps!!!!!

I am a developer at Microsoft so I know a thing or two about computers. The best PC cleaner and antivirus program is CCleaner, it's very light and it's the only antivirus/cleaner with a 99.99% detection rate.

CCleaner is also a PC booster so your computer will be running faster than nomal. Download it here for free: http://bit.ly/1mQZhtQ

Your PC is constantly reading and writing to a registry while you work, or while you are playing games, on it. This all happens in the background without you even noticing.When your PC was new, this was no problem, but the longer you have your computer, the more programs you install on it and the more the registry becomes bloated and damaged.This is the reason that your PC is running slower and might crash all of a sudden without warning. Your computer needs to work hard to go through all the registry bloat, or it might simply crash if it comes across a faulty entry.A registry cleaner will scan and repair your registry.Frequent maintenance using a registry cleaner is crucial to make your computer go faster.I should like to commend Registry Easy http://best-way-to-improve-pc-performance.com/ to you !
