Any idea where the problem is with this build?

Hello there, my new stuff ordered from Overclockers arrived this morning (chosen with thanks to much lurking and reading the forum, naturally):

Lian Li PC-7+ case
Tagan TG530-U15 530W ATX2.01 Easycon SLi Compliant Modular Silent PSU
Gigabyte DS3 mobo
E6600 Core 2 Duo
Scythe Infinity Heatpipe CPU Cooler
GeIL 2GB (2x1GB) PC6400 800MHz Ultra Low Latency DDR2 Dual Channel Kit
Seagate Barracuda 7200.10 320GB ST3320620AS SATA-II 16MB Cache
HIS ATI Radeon X1900 XT ICEQ 3 SILENT Heatpipe 512MB GDDR3 AVIVO TV-Out/Dual DVI

I think it's probably the most money I've spent in one go :eek:

Put it all together and switched it on, the fans are going but that's basically it. My LCD just stays on standby, no display at all and no beeps. I messed about a bit with no luck, occasionally I'd switch it on and the monitor would come out of standby for half a second, there'd be a beep then the power goes off, then it'd repeat the same thing. I've had it all out and lying bare on my desk (as per the v. useful sticky) to make sure the graphics card was seated properly but there's no change.

I assume something must be DOA, but I'm not sure how to tell what. Unfortunately I've not got another PCI-E system in the house to test the GPU with. I'm guessing the mobo's OK if the CPU fan's going?

Any advice more than gratefully received, I'm pretty stuck at this point

no beeps has always turned out to be a dead motherboard in my experiences

have you got another psu to try and have you tried with 1 stick of ram?

Switch the PSU's adaptor the other way round on the M/Board

Ah well, cheers for giving it to me straight

I've just tried both sticks in on their own and no joy. My other PSU's inside a Sonata and I assume getting to it will be a bit of a pain but I'll give it a try tomorrow if there's a chance it might save me messing about with returns and all that.

I think the same thing happened to me, when I was building this computer. What the problem was I was using the wrong 4 pin ATX cable. Make sure you plug the one with the latch on it into the seperate 4 pin socket.

Sorry if it makes no sense, it's hard to explain in words.

Sorry, not sure what you mean.. Isn't there basically only one way you can put the PSU's leads in? Or is it something else?

The 4 pin 12v cable? There's two with the PSU, one that's permanently attached labelled P4 (I think) and another one for the modular bit labelled P4+, I tried the other one too but there was no change.

Yeah that's what I'm talking about. I was using the wrong one which meant that when I turned the computer on the fans would spin, 1 beep from the mobo, a flash from the case LED's and that's it.

If you've tried switching them and got the same error, then I don't know what else to suggest sorry.
