Unmountable boot volume
What could cause this problem? About every 2-3 weeks, the old blue screen of death pops up and tells me my puter has died(R.I.P). I have to go to recovery console and chkdsk and fixboot and then everything is ok again. There seems to be nothing to provoke this unmountable boot volume, it just shows up and won't start up. What can be done to prevent this from occurring again?
