I would make friends with someone that has a stable computer for sale John
Try restoring the MBs default factory settings in the BIOS, they are sometimes listed as one of the following " factory defaults" "most stable" or on newer boards "optimized" please note that if you have both the "most stable" and the "optimized" options in the BIOS you should choose the most stable" option as in this instance the "optimized" settings are a form of overclocking that can cause instability.
Save the new settings, exit the BIOS, restart the computer, test by using the computer as you normally would, post back with an update once you have done this.
Doing the above will disable any OC and if the PC runs stable you can then look at manually OC the RAM in increments until you get to the 2933MHz max.
In addition to the above, make sure that the Windows Power Plan is set to Balanced, Ultra and High Performance are a form of overclocking that is known to cause stability and overheating issues, the setting should only be used for gaming type notebooks that have a discrete GPU that needs the extra power.
