Thanks to all. This is for me truly enigmatic, something I have never experienced before.
Firstly, I would try running with one stick of RAM, at least with two different sticks (in case the first stick of RAM is bad obviously.) Perhaps it will get your motherboard up long enough to post so you can change the DRAM voltage to 1.7 (for starters). Some boards don't apply enough current to all 4-Dimms when populated (although rare nowadays.)
Well if you have a spare PCI-E video adapter to test, you can always quickly ascertain if its the card or the motherboard. Mobo will fail with all GPUs, not just one.
Statistically speaking hardware failure wise, this is the order of likelihood from lowest to highest.
RAM -> PCI-Express Peripheral -> GPU -> Motherboard ==========> CPU
CPU failure rate is very low.
RAM for me has been approximately 1/8 ~ 1/10 sticks have failed on me.
GPUs have more reasons to likely to fail due to simply due to their complexity and heat production. They have a Processor, Memory (RAM) and chipsets.
Yes GPUs need their own powersource and your motherboard will not b00t up if is not firmly connected to either a PCI-Express Six Pin cable or two of them. MAKE SURE YOU ARE NOT USING AN 8-PIN PCI-Express cable and only inserting 6 of the 8 pins (leaving two outside.) If you have used the 6 pin socket with an 8-Pin plug, you may have fried a part of the card (permanent damage.)
The CPU only has a 8-socket, and the motherboard has a 24 socket (the bigguns.)
Motherboards are virtually equal with GPUs, but I think Motherboards are RMAed more due to inadequate operator experience way more than failure. You have virtually total control from BIOS and can usually easily screw it up. However, they are not physically rigorous and due to their size, and the complexity of objects attached to them, or added to them, make them prone to user error.
I believe the failure rate of a CPU is extremely low, especially if properly installed, correct voltage setup, and adequately cooled.Edited by RagingCain - 11/19/10 at 9:21am
