Aaaaarrrrrrrrggggghhhh

I wanted to build a new system for my grandfather as his is quite slow. I've built one other computer before that went smoothly and I foolishly assumed that this one would be the same. Here are the specs:

Intel i7 920
4GB DDR3 Mushkin Ram (3rd DDR3 spped, can't remember)
Gigabyte EX58-UD3R Motherboard (I think this is the problem)
Antec Truepower 650W PSU
Asus EAH4550 512mb
1TB Seagate HDD (5900 rpm version)
Generic Antec Three Hundred Case

I put all the stuff together, careful to keep myself grounded by touching the PSU of a turned on computer. Everything went together smoothly, I plug it in and I see a flash of an LED, a whizz of a fan and then nothing. Less than one second of juice. Now here are the specific symptoms:

PSU fan spins but stops first.
CPU fan spins.
Case fans spin.
No lights on the Mobo on.
No display.
No sound (beeps or otherwise)

I have tried:

Switching RAM into all slots, separately and together.
I have re-aseated the CPU and heatsink twice.
Checked that the thermal paste was evenly spread.
Tested the PSU in another computer, which I knew was working. The computer turned on. Used the PSU from the working computer in the new computer, nothing happened.
Took the whole system out and built a bench system on the Mobo box. Nothing.
Reset the CMOS. Nothing.
Took out the GPU, re-seated the GPU, etc. Nothing.
Prayed to every god I could think of to get my computer working. Nothing.

Any suggestions? Sadly, it's Canada Day tomorrow and all the stores are closed to returning any parts will be hard. I will have to do that on Thursday. Still, if anyone has any suggestions that would be great.

EDIT: And I checked the mounting posts in the case. All are good.

Have u tried shorting the "on" switch with a screwdriver or something? Is that what u ment buy "building on mobo case"?

Can u try use a different cpu, fan just to rule out those two from being "broken"?

edit:

Does ur grandfather really need an I7 in the 1st place? unless he is some sort of extreme gamer or video editor. If it were me, I would have just got him a core 2, or at best a quad.

Ok, I had the same exact problem. With the same motherboard too. It turned out that triple channel refused to work. It took me hours to figure out, but my problem was that one of the CPU pins on the motherboard was bent. I moved it back to place, reseated the CPU and ta da! That may not be your problem though.Luminouslight

I'd say it's your motherboard, although, is your grandfather going to play Cryostasis, Crysis or GTA IV? That is quite a powerful PC and if he is just going to check mails then I'd suggest you sell those parts if he isn't going to use it for gaming.

Had this exact problem with a dead motherboard. Examining it, I couldn't find a single thing wrong with it, but it was definately the motherboard.

To be honest, I kind of retired the idea of an SSD to laptop configurations, not desktop. I'll have to look into it. Thanks for that.zombiefruit

No probs.

btw, tf2 rocks!
