I have been getting a lot of 'blue screens' lately, all indicating differing messages. I allowed the computer to self "check disk" but it crashed so I had to use the button to turn off and back on. I opted for a non destructive system restore. The computer
crashed at about 26%(40+ minutes without any change). The power was turned off. I restarted ,hoping to try again but got the "ntoskrnl" message. I put in the recovery disk in and so far it has reached 32% and seems to have frozen again( about 25 minutes so
far). If all else fails, if I opt for the full system reformat, will that reinstate everything back to "as new?"
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.
