Computer rebooted from Bugcheck: 0x100000d1

Hi everyone! I got some problem with my laptop Sony Vaio VGN-A115S...
This is problem just happen a week ago and i can't fix it....
The bugcheck was: 0x000000d1 (0x8a000000, 0x00000002, 0x00000000, 0xba915a98)

I saw one post regarding 0x000000d1 but maybe my situation is different.... I need some help and advice with this... thank you..

Intel(R) Pentium(R) M
Processor 1600MHz
1.59GHz, 2.00 GB of RAM

I installed Windows XP Professional Service Pack 2...

A couple things to start:
>> Any new hardware? or device drivers? as your bugcheck code is usually related to a driver issue
>> Update to XP SP3. Even if yours aren't USB related, See USB Device Problems? Check for Windows Updates for tips on upgrading XP SP2 to SP3

Thank you for the reply...

I dont have any new hardware connected in my laptop.... I will try SP3
