Ive had a dell inspiron 1100 laptop for less than a year. While being at university ive noticed it to be much slower and always creating those error message boxes on the screen. I think this is much to do with spyware and adware being added, or even viruses. Ive tryed all types of ad spy removers and virus software but feel its still causing problems so have resolved in reformating the hard disk?
How can i do this?
