im using a dell inspiron 6000 with xp and have had my laptop for around 3 years now. i have recently been getting a message saying the " ati2dvag driver display has stooped functioning correctly". this problem has resulted in jerky stuttering video performance ( in any video form i.e dvd's, internet videos etc) and also slow performance of my laptop on a whole ( this is not due to any spyware etc, and so i have narrowed this problem down to this error message). has anyone else experienced the same problems or does any one know how to rectify the problem? any help at all would be highly appreciated.

i have a 128MB DDR ATI MOBILITY RADEON X300, and 6000 DISCRETE GRAPHICS: PENTIUM M 740, along with 1024MB 400MHZ DDR2 SDRAM MEMORY
