If it is indeed the CPU it could still shutdown even after you fix the grease and heatsink. If so the only way to weight it out is to either inspect the CPU visually or swap in another cpu (making sure to put a heatsink or fan on it and testing it.

Does this bios setup have CPU temp monitoring? If it does, monitor the temp and see it goes up a bit before it quits, if it does try replacing the thermal grease, make sure the heatsink is properly seated and be sure the fan is working properly. Also the ram can cause this, try moving or swapping the sticks. Clean the contacts lightly with a soft rubber eraser.
