I am using Windows XP Home Edition, And My system keeps shutting down and this blue screen appears saying: Your system has just recovered from a major problem

Technical Support:

STOP: 0x00000050 (0xfff0beb8, 0x00000000, 0xf38f654b,0x00000000

vsdatant.sys Address F38F654B base at F38E5000,DATESTAMP 40a88e61

And it also said something about PAGE_FAULT_IN_NONPAGED_AREA,  And I have tried to figure out what driver it could be talking about, but I have NO IDEA, and I really do not want to make things worse....Any suggestions, PLEASE??
