Hello,

I just assembled my new computer, but it doesn't boot, when I press the start switch, all the fans start working for about 2 seconds, and then they stop (except for the cpu cooler fan, which just twitches at the start and the end of the 2 secs). They'll keep going on and off untill I switch the PSU off.
I've tried all the basics, like stripping it down to cpu + fan + 1ram stick, outside of the case, and the problem stays

The specs are as follow:

PSU: Corsair cx500 80+ bronze
MOBO: Asus p8h77-i
RAM: Patriot viper 2x4Gb 1600MHz
GPU: Sapphire Tech's Radeon 7870 OC GHz edition
CPU: intel i5 3570
HDD: seagate barracuda 500Gb 7200rpm


Note: At first I just thought that the PSU wasn't strong enough, but since the same problem occurs after stripping it all down, I don't think that's the problem

Note2: I also made sure to discharge any static electricity before opening the boxes, and there are no obvious signs of damage/dirt on the CPU connectors

The green LED lights up when I hook the PSU up, and something else I hadn't said before, the HDD beeps with every boot try, just before everyting going off again

I have done it with the jumper, it's a simple 2 pin cap that you have to switch pins and put back on the original position

Screen was connected to the GPU, but it acts the same when connected to the mobo

I only used the adapter on the 7870, since it has no d sub ports, I'll try using the adapter on the mobo, though it doesn't look like the screen is the problem, only a consequence


Also have put the mobo on its standoffs, still outside the case, just in case the cardboard was somehow conductive

»»»»Oops, adapter doesn't fit, has some extra pins that the mobo port doesn't

Yes, it is new
Nope, it beeps only once, simillar to what a front pannel speaker would do in normal circumstances

Speaking of which, browsing asus online help website, I think a speaker would help to identify the cause of the problem... to bad I don't have one, since I built a costum case

the fans work, momentarily
No, I have no other PSU readily available
Yes, it is all brand new, but I fear I may have ruinde something myself, and also, there's the pinpoint problem..
And the HDD beep may or may not sound like a braking squeal, I'm really not sure

As in asus online support:

"1.4.2.1 Memory issue: Beep (1 long 2 short)..."
"1.4.2.2 Graphics card issue: Beep (1 long 3 short)..."
"1.4.2.3 CPU issue: Beep (5 short)..."

Do you know of anyway I could ghetto the speaker, with an LED or something? I think the speaker is the key to pinpoint the rot

busted the intercom speaker trying to get it out of the intercomm, screws were too rust

the gba sp speaker work on the 9V battery, see no reason why they shouldn't on the mobo

So I can assume the mobo isn't beeping

"
1.4.1 If there is no beep, please contact your retailer for a check..."

I'm going to try and switch out the PSU tomorrow.. hope that is the problem, cause it (probably) means I already bought it deffective.
Kinda worried that returning something will take a lot of time, cause I bought it online, and distribution services on my country do not have the greatest of reputations

I think the problem was with the PSU, but doing the paperclip test sorted it out, somehow, anyway, thank you.

Btw, I've started another thread on another problem I now have, regarding the installation of windows 7, maybe you could help me on that aswell? :)
