I have to reset the cmos by removing the battery from the motherboard every boot.

Current specs
Mobo: ASUS SABERTOOTH 990FX R2.0
CPU: AMD Phenom II x6 6-core AM3 processor
Video: MSI Nvidia GTX 660ti
RAM: 8 gb (2x4) Kingston HyperX Black DDR3 1600
PSU: RAIDMAX RX-600AF 600W
Case: NZXT Phantom 820 White

I had previously tried a MSI 970A-g43 and it was doing the same thing so I figured it was the motherboard. I bought the ASUS SABERTOOTH 990FX R2.0 and it is doing the exact same thing!

It is odd that the same thing should happen with two different mobos.

Remember, when doing a BIOS Reset there are four steps.
1. Disconnect the power cord. Remove the battery and move the Reset jumper to the "Reset" pin pair, leaving it there for 10-15 sec. Then reposition the jumper to the storage position and replace the battery.
2. Reconnect the power cord and boot into BIOS Setup directly. Go to one of the last pages and find the menu choice to Load Optimized Defaults. Do that.
3. IF you know you had any changes in place - like, using an added vid card instead of the on-board chip, or setting SATA Port Mode, etc, re-do those.
4. SAVE and EXIT so your changes become permanent.

Step 2, Load Optimized Defaults, is important. A Reset...

Step 2, Load Optimized Defaults, is important. A Reset, even if done properly, may NOT install all the correct default settings.

Still, it is puzzling why you should get into this situation in the first place. Have you checked your battery in case it is dead?

This fixed the problem and it will boot normally now. The MSI 970A-G43 I was using before is also now confirmed DoA.
