Hi, 

I recently bought M2N-E SLI motherboard from ASUS, OCZ DDR2 Platinum Series PC6400 RAM, and NVIDIA GeForce 8600GT PCIe.

Put everything together, but the monitor (VGA input) does not seem to receive any signal and stay blank. (normally you see the memory count, bios information etc when booting up).

Question is, is there a way to check if it's due to the Graphic card, or RAM, or the motherboard itself by not installing the RAM onto the Mobo? (i do not have spare mobo/Graphic card since it's been 8 years since i built my last PC and the old parts won't fit into the newer ones).

Or are the items i bought have known compatibility issues? (They should work 
together by just reading the specs required.)

Thanks a lot for the help :)
