Hello guys,I've recently join these forums to seek aid in seeing whats wrong with my computer. And to be honest i'm no expert at this stuff so help me out. you see whenever I turn on my computer its all normal start up and all that untill it goes to the desktop screen, it's completely blank. I can hear the starting up noises and just yesterday I've installed a new graphic driver (RADEON HD 4670) and it worked for the first day, then the next day I turn my computer on it comes up with this 'blank screen', And I really wanna avoid re-formating. can anyone help me?
