Maybe the mobo thinks the clocks are unstable because it doesn't shut down properly with a reset.
Hmmm this possibly could be the issue.
Who overclocked the system, was it somebody who knew what they were doing?![]()
What causes you to keep having to use the reset button?
I've had 2 Sandy Bridge systems with fully stable overclocks for over 12 months.
I don't think I've ever had to use the reset button due to the system locking etc.
