Today I installed a new CPU cooling unit as the old one (that came with the computer out of the box) was not doing a good job anymore. Removing the old heatsink also pulled the CPU itself off the motherboard as the thermal compound had stuck the two together well. I replaced the CPU and connected it back up properly.
However, when I started my computer back up, all I got was a black screen and a notice saying that my monitor was not receiving a signal. Eventually, I tracked the problem down to the RAM. The computer came with 4 2GB sticks of RAM and I am not using anything other than the original sticks of RAM. With 1 stick in slot 1 or 2 sticks in slots 1 and 3, the computer starts up fine. However, if I put anything in slots 2 or 4, I get the same problem wherein I get a black screen, no signal error and never get to any part of the start up to select boot devices, etc. Running CPU-Z I found that my computer is on single channel for RAM and it seems it wont boot if it tries to go to double channel.
The computer worked perfectly fine with all 4 sticks of RAM in until I replaced the old heatsink with the new one.
Specs:
Motherboard: Gateway RS780
RAM: Nanya 2GB Serial #: NT2GT64U8HD0BY-AD
CPU: AMD Phenom X4 9750
