Two identical systems, same problem. No post/video.

So I was building a new core 2 system and my roommate wanted to try it out too so he bought the same setup as me.

Gigabyte 965P-DS3 Rev 2
E4300
2GB(2x1GB) Corsair XMS2-6400 (1.8V)
eVGA 7600GT
Thermaltake TR2 430W PS

I left the DVD drive and hard drive disconnected.

Build went smooth with no noticeable problems. Plugged it into my old school SyncMaster 753DF CRT monitor (my LCD died about 2 weeks ago and I picked this up while I wait for a good deal) and powered her up. HSF, case fans powered up but no post, no video. My case didn't come with a speaker so I couldn't tell if the mobo was trying to beep at me. I removed 1 stick of ram leaving me with only 1 stick in slot 1. Rinse repeat, no video. Swapped the ram, no video.

Took my roomates exact build (with a different case that HAD a speaker), connected the speaker and powered up. Once again no beep and no post. Now the odds that both of us received dead mobos or cpus isn't that high, so I googled like crazy. One result turned up someone who mentioned they had the exact same problem and discovered their CRT was "too old." He posted that once he plugged in a brand new LCD it worked fine. Is that even possible? How can a CRT be too old?

I'm really stumped on this one. Any suggestions? I know you enthusiasts will say 430W is not nearly enough for an optimum system, but it should be powering my mobo ram and cpu without a problem.




 
Just curious, but do you have all the power connections plugged in on the motherboard? Check page 19 of that manual...let me know what you find out! Also make sure the graphics cards are seated all the way.

**As far as the monitor being too old??**
Never heard of that situation. I have heard/seen where the monitor will work in during startup, due to a low resolution, then not work when the Welcome Screen/Login Prompt appears because the monitor is too old to display the resolution.
 
It's funny that you mention that. Just last night I realized that was a missing piece. I went to plug in the 4 pin ATX_12V power only to discover my power supplie's manual didn't give the right color wires for its pin out. I plugged it in staying consistent with the way I plugged in my 20 pin ATX power.

With the 4 pin in, the thing doesn't even get power. No fans spin, nothing.

If I remove the 4 pin, unplug the power and plug it back in everything powers up again.

Dead board?
 
Are you sure you are using the right connectior? Do not use the 4pin piece that separated from the mb connector. There is a completely different 4pin 12v connector.
 
The only connectors that I have other than IDE/SATA are the 20pin with a 4 pin splitting off from it and a 6 pin. I have no other 4 pin connector.

EDIT: And yes, it's now obvious to me that that 4 pin splitting off is to make the main ATX connector either 20 pin or 24 pin.

Futher EDIT: http://www.thermaltakeusa.com/product/Power/TR2power/w006970/w006970.asp

This tells me I do indeed have a seperate 12V connector. I'm almost 100% sure I checked and checked and checked for one last night, but stranger things have happened. I'll look when I get home from work. Thanks for the help.
 
No, it was there. I swear my roommate and I searched for it last night but didn't find it. My roommate just went home on his lunch break, located it and plugged it in. Posted just fine.
