Ok so my laptop is being a peace of crap. As if i dont hate vista enough, it keeps finding ways to make me want to kill it. I have an HP pavilion, with Vista Home Premium, and a stupid problem. Aparently, its an entertainment computer, but, when i watch movies or play games like minecraft, source games (especially source games), it gets really laggy. Its not that my laptop can't handle the graphics, for the first 10 minutes it runs really smoothly. But then for 1 minute it gets really choppy, then it goes back to being smooth... then it goes choppy again. i've tried lowering the graphics, particularly the textures, but it doesnt seem to help. I've tried optimizing my processor by removing processes and services i dont need. i've also tried lowering the priority of certain processes such as windows update, and my antivirus. These seem to work in a small way. Any suggestions on how to make it run smooth permanately? is there any process that tends to make the computer lag only while an application is running?
