i have 2 x 4GB corsair vengeance 1600 mhz ! i have 4 slots in my motherboard, and put them in the same color ! if thats what you were afraid of ! We did RAM tests on LINUX for 4 hours and they seemed ok
I have done the part with the battery removal and nothing !
BTW the PC Shut down before i install the latest BIOS version F7. So i will test it now with the latest version ! Maybe you thought it shuts down with the version i installed !
