Customer describes Blue Screen stop error she gets. I never saw error first hand. I had to depend on somethin showing up in Event Logs. Event ID 1003 error has been showing up once per day. I assume this is the error causing the system hault. The text of the error is: "Error code 0000007f, Parameter 1 00000000, Parameter 2 00000000, Parameter 3 00000000, Parameter 4 00000000. Need to find out what is the casue ASAP.
