Ive had my Dell laptop for about 3 years and for the past year or so I have been unable to turn off my comp because everytime I do Windows never starts properly and makes me so system repair a couple times until finally it will boot properly after about an hour of repair. If anyone knows or has heard of a similar problem please let me know. (I have reformatted my comp a couple times in an effort to fix this and any other tech problems my Dell gives me)
