spontaneous shutdowns

My computer has been restarting itself and I have been trying to troubleshoot the problem. When I reboot, i get a "this system has recovered form a serious error" message and i send the info to microsoft. They say that the restarts are caused bu an "unknown device driver", which I also can't find. I went to event viewer and I found an event error. It says:

System error
category (102)
Event ID 1003

Error code 100000d1, parameter1 00000010, parameter2 00000002, parameter3 00000001, parameter4 f6ce7129

Do you have any idea what this is and how I can correct the problem?
