I replaced the low voltage (1.35v) G.Skill DDR3 with a new Kingston Value Ram (1.5v) 2GB DDR3 PC3 10600/1333MHz
Inserted in both slots, same 3 beeps followed by shutdown.
I just placed a new stick of 1.5v DDR3 4GBs (my 3rd RAM purchase) and placed in either slot and still get 3 beeps. I've unplugged the PSU and internal battery and waited 45 minutes numerous time. I even reseated the CPU.
Please help! Is this indicative of a bad motherboard?
