hey i really need some help. I constantly get an blue error screen. it says the following: DRIVER_IRQL_NOT_LESS_OR_EQUAL STOP: 0x000000D1 (0x00000008,0x00000002,0x00000001,0x0F70B410F) i have a Sony Vaio. Model No: PCG-K25 i have Windows XP Home Edition SP2 it is only about one year old and the error has only occured for about 1 month. i did try to install a scanner but the drivers were not compatable with Windows XP. since then i have even reinstalled my C: drive and reinstalled Windows. if anyone has any suggestions, help would be greatly appreciated. thanks.
