Ive got a hp pavilion ze5000 notebook. Its got a 2.4 ghz proccessor, 512 mb memory, ati mobility radeon graphics. Problem is that when i move a window it leaves trails behind it (not permanent, about a 0.75 second delay before they go away) and when i play a visualization on Windows Media Player they appear very very slow, both of which will bring my cpu usage to 80-100%. Ive tried changeing resolution, color bit, and turning off hardware acceloration. Any ideas on how i might be able to fix this?
