hi guys, i have a dell laptop and never had problems. lately when im on internet then my screen goes black for a second and then it comes right again. my pc is also slow and i defragmented more than once and always get rid of clutter but it doesnt seem to go faster. your help will be much apreciated.
thanks-stephen.
