Remove the known good RAM module and try to boot the system.
If the system fails to boot, shut it down and move the new RAM module to the other RAM slot and try to boot the system.
If the system fails to boot, the new RAM module is faulty. If the system boots, then the second RAM slot is faulty.

I am not sure about DDR2 but the 775 socket boards with DDR3 required low density DDR3. Crucial does not list your board, Best to get the numbers of the one that is working and buy a match to it. May find on eBay.
Yes I thought so, has to have chips on both sides, If you can find some Kingston KVR667D2N5/2G the are supposed to work, Get a pair if you can find them.

That would entirely depend on what chipset it has.

If your motherboard has G45 like you listed in the title, then it supports up to 16GB of DDR2.

If your motherboard has 945GC like you suggest by "945" in the OP, then it only supports 2GB.

So which is the truth? There's a huge difference between those two chipsets, which were made three years apart. One supports only Dual-Core and the other can accept Quads too.
