I am using a quite old MSI 740GTM -P25 Motherboard with an AMD Phenom 2 X2 555, 4 Gigs of RAM.
Here's my problem. When I place both RAM sticks (2x 2GB DDR2 Corsair) in the two available slots of the motherboard. Once I boot it up, the computer won't boot. I get no signal. But, if I put a RAM in the first slot, the computer boots perfectly.
I attempted putting the working RAM into the other slot but did not get success.
