Gigabyte z68; i7 2600k was at 4.5; 2x Kingston ssd in raid0; Antec 680 power supply...all other hardware was striped for testing

My system freezes at random..the type of freeze is basically no mouse and keyboard function with the desktop at a stand still..no blue screens no messages or notifications before the freeze.

I had an overclock going in the bios for almost a year without a problem. What is weird about it is I put my bios back to "optimized settings" and it doesn't freeze anymore.

Also note there are no temperature issues and I disconnected everything except motherboard CPU and C drive and it still freezes. I also don't have any extra CPUs or motherboards to test further

Any idea's?
Looks like for now I'm staying at optimized settings until I decide to get a new system.

No..I set up the OC a while ago ran Prime for a few hours and it was fine back then...went almost a year of gaming on it and it was good..then recently I had this problem..I guess I could try it
