Driver_irql_not_less_or_equal

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.

When Windows crashes with blue screen, it writes a system event 1001 or 1003 and a minidump to the folder \windows\minidump. Check system event 1001 and 1003 and it has the content of the blue screen

Event ID: 1001

Microsoft Windows..... A dump was saved in: .......

Control Panel -> Adminstrative Tools -> Event Viewer -> System -> Event 1001/1003. Copy the content and paste it back here

Zip 5 to 6 minidumps a zip file and attach it here. Techspot has a upper limit of 100K per attachment. I will study the dump and find out the culprit.
