Hahaha yea, I think we've pretty much settled on replacing the motherboard. Going to go with this P45 based Asus board: http://www.newegg.com/Product/Product.aspx...N82E16813131299

Alright guys and gals, did some more tinkering to no avail... Here's what went down: All outside of case (And used BOTH PCIe Slots): - New motherboard, new processor, new memory, old GPU. NO DISPLAY - New motherboard, new processor, old memory, old GPU. NO DISPLAY - New motherboard, new processor, new memory, new GPU. NO DISPLAY - New motherboard, new processor, old memory, new GPU. NO DISPLAY - Old motherboard, new processor, new memory, new GPU. NO DISPLAY - Old motherboard, new processor, old memory, new GPU. NO DISPLAY - Old motherboard, new processor, new memory, old GPU. NO DISPLAY - Old motherboard, new processor, old memory, old GPU. NO DISPLAY - Tried all above configs. alternating with 1 stick of RAM, then both as well. Kind of running out of options here... Short of replacing EVERYTHING I/we cant understand what else it could be. Oh, and when referring to "new GPU" we're referring to my eVGA GeForce 8800GTS G92 (In which I'm using to write this post!). With all the above listed configurations, still nothing was displayed on the screen (Which is confirmed functional).

I think all of the resolutions posted in the last 3-4 replies would be pretty much resolved/ruled out by switching out the motherboard which we did... Would a new 750i still require a BIOS flash? I would think probably not, right?

With a new CPU, Memory, and Motherboard - it seems like i've basically taken those steps already... And no, I havn't flashed the BIOS because a) This is a whole new motherboard, and b) there is no video, so it'd be hard to do it...

I would think the CMOS battery wouldn't cause an issue of this caliber, and no the motherboard does not have onboard video...

No beeps, and yes the processor was swapped out for a new unit... This just seems odd, I feel like we're missing something...

It's a fairly new rig, and no it does not POST at all...

Both monitors/cables function correctly, and both Video Cards function correctly when used in MY motherboard. Havn't tried the second PCIx slot on either of his motherboards, but it seems odd and uncommon to me that both primary PCIx slots (on his orig. board, and the 750i, would be faulty). Also, his RAM, and hard drive work in my machine as well...

Bump...?

Even with that being said, there's no way both those motherboards' top PCI-e slots are bad... And if they are bad, who would want a motherboard with only one good slot?

As far as my understanding goes, unless SLI is being used - the top slot is the one you use... The top slots were used on all three boards... Isn't the bottom slot only a 4x slot anyways?

Do you guys think it's possible that the PCI-e slot on his 680i is bad, and the new 750i he ordered shipped with a bad PCI-e slot?

Humm, I think you misunderstood the post. His graphics card, and mine as well, both run successfully in my machine. In his machine, neither display anything - on either of his motherboards (the 680i and 750i)...

Alright guys and gals, here's the deal. My buddies computer will not display ANYTHING on the screen. Simple solution right? Wrong, the graphics card is completely fine. We pulled the card and threw it in my system (<-- in sig) and it worked just fine. Since then we've tried replacing: the motherboard, the ram, the processor, and even the power supply (after all of them seemed to have tested fine in my machine). Interestingly enough, before we swapped out motherboards we tried my graphics card in his machine and it didn't work, so we figured the socket was gone on the motherboard. New motherboard, same thing (even a newer model motherboard). So we're stumped, we've come to you guys looking for answers. The specs of his machine are as follows: - eVGA nForce 680i LT Motherboard (Replaced with eVGA nForce 750i SLI) - Intel Core 2 Duo 2.4Ghz Allendale (Small OC to 3.0, replaced with C2D E7300 2.66Ghz Wolfdale) - 2Gb Crucial Ballistix DD2-1066 (Replaced with a matching new set) - eVGA GeForce 8800GT SuperClocked 512Mb - PC Power & Cooling Silencer 610W To recap what we've done: Tested his power supply, and graphics card in my machine. Tests came back positive. In his machine, we replaced the graphics card (with mine - didn't work in his machine), the motherboard, and the RAM.

Your user name doesn't have anything to do with a C6 Vette does it? Cause if you can afford a system like this AND a C6 Corvette YOU DA MAN. Hahaha.
