hi i have so many problems with my computer. the main ones are that it runs too slow and some blue screen problem. first, the blue screen problem is the more important. after i leave my computer on without any input from me for sometime a blue screen error comes to it. it is like some software tries to run and fails. but i havent installed anything and the error that is shown in the blue screen is different everytime. if i have input like mouse or keyboard in the computer the blue screen doesnt show up. if i leave it 'alone' for some time it does this blue screen error. help ! !
