What is "killing" my RAM?

Hello AnandTech forum. I bought my system about one year and a half ago. Just a few minutes ago my second stick of RAM has "died". The computer refuses to boot up if I have it installed in any slot. It's 2 sticks so I am currently using the other not faulty one.

Basically I am trying to figure out what to do. What exactly is "killing" my RAM and how can I find that out?

SYSTEM:
ASUS M4A785TD-V EVO
Corsair XMS3 DDR3 1333MHz 8GB CL9
AMD Phenom II X4 955 Black Edition
MSI GeForce GTS 250
Corsair TX 850W PSU

I am strongly considering buying a new mobo and cpu but I want to make sure that it is not the PSU or the RAM itself causing this.
 
Well how about this. Since I had two different RAM sticks "die" in the same slot, while the other stick stays the same. Would it be safe to assume its the motherboard causing this?
 
DDR3 is designed for a maximum of 1.95V, and I would physically measure the memory voltage with a meter, in case the motherboard gives inaccurate readings. If you experienced unreliable operation before the memory was destroyed, there could have been excessive ripple or voltage surges caused by fautly capacitors not providing enough filtration.
 
Everything worked really well from what I experienced, which is the weird part, as this "happened overnight". I noticed nothing when i shut down my computer to go to sleep and in the morning the next day it wouldn't boot.
 
you know my voltage regulator on my car failed once feeding everything 17V. the lights got really bright. i was smart enough to pull over and drive off battery since 17V would cook every bit of electronics. be wise and figure out how to measure your voltages before you fry something.
 
So if I get my hands on a voltmeter and the voltages seem fine. It has to be the motherboard? (I will try to get a voltmeter and test the PSU asap)

Since 2 different memory sticks broke in the same slot under 3 months, I don't think its the ram stick itself being faulty.

Not if any motherboard voltage is bad. It has several voltage regulators, including one for the CPU and another for the memory, because the PSU doesn't generate the voltages needed by those devices. Unfortunately the measurement points aren't obvious.
