"Your computer restarted because of a problem."
"Your computer restarted because of a problem" is the message we get every time our computer randomly shuts down and restarts.
Series of events, spanning about 2 months:
We installed new RAM, a week or two later it begins to restart in the manner above. Seldom at first, but then occurances increase.
Eventually our computer shuts down and will not reboot.
We take it in to get service and are told our hard drive is failing.
We had a new hard drive installed.
Upon returning home with the computer, it has restarted in the same manner as above 3 times within a 12 hour period.
We tried removing the new RAM to see if that made it difference, it didn't.
What could be causing the computer to restart like this? What can we do to fix it?!?
Thanks for your time!
