screen flashing when starting WMP

[jayno20]

anytime i go to watch a movie, it flashes black real quick before it starts and then again after i close it... any idea why? (ATI Mobility x1300 video card, and latest catalyst drivers)

OK i think i found the problem... my ati card was set ot not run as well on battery it was set to step down after i fixed that so far it hasnt done it again.... does that seem like that could be it to you guys?
