For the past couple of weeks, my computer has been restarting itself. When I check the event viewer, the only event that corresponds with the time of restart is Event ID 64, which reads as follows: "Certificate for local system with Thumbprint 00 a8 d0 db 52 d2 7c 97 18 ed 7e 98 f5 f7 83 f8 f2 52 04 d8 is about to expire or already expired."

    Hi,
    According to Event ID 64 — AD CS Certification Authority Certificate and Chain Validation, we can see:

    A computer certificate on a managed computer, not a certification authority (CA), must be renewed when it passes 90 percent of its validity period or has expired. Because a successful renewal will generally be initiated before the certificate reaches 90 percent of its lifetime, this error indicates that there may be a problem automatically obtaining a new certificate via autoenrollment.

    Try to find your CA, and you could see the cert's issued to computer. You should be able to delete or renew it.
