Hi,
you are talking about the client computer I assume.
If this is the case there may be a reason for your experience out of the range of Windows Home Server recovery possibilities - like broken sectors on the disk, faulty memory, overheating due to to much dust on the coolers and case openings etc.
In this case restore will not fix the misbehavior before you can fix the base problem.
Best greetings from Germany
Olaf
