Video starts to jerk in full screen mode

Specs: Windows Vista Home premium edition
Hi I have a Acer aspire 5520 laptop with Windows Vista Home Premium Edition as the operating system. I have had this laptop for 2 years. Recently I have been facing problem when watching video or playing games in the full screen mode. The video starts to slow down after 30mins into watching and gets bad (as if watching a slide show) as the time progresses. The system fan starts to scream as the video starts to jerk. This all happens in full-screen mode only, if I switch off the full-screen mode then the video runs fine but the system fan continues to run at higher RPM. I have tried different media players, but had no luck. I have re-installed the video graphic drivers (which is Geforce 7000M) and removed all unnecessary programs. But the problem still persists, can any one direct me towards a credible solution. Thank you

it may be a heat issue. Open your computer up and clean off any dust build up, preferably with a compressed air can (do not use a vacuum). Are you running lots of peripherals internal or external? If so then your power supply may not be providing sufficient wattage for everything to run properly, which would then surely make your optical drive over heat and make you video quality choppy.

Yes, overheating. Is the laptop's fan(s) running.
The laptop might need a cleaning:

"The system fan starts to scream as the video starts to jerk"

That doesn't seem like a hardware issue to you? Try blasting some compressed air into the cooling vents, they're probably all dust clogged.
