ASRock Z68 Extreme7 Gen3 won't turn on?

[conabis]

Hi

I am currently building a new PC and after buying all the parts and putting them together my mobo wont turn on, i plugged everything in as instructed and when i try turning it on it makes a single low dull beep which seems to come from the LAN input, no lights or led codes show, just the beep.

This is the 2nd PC i have ever built and it has been a long time since i have done it so maybe i have something wrong.

Does anyone know what to do????

ASRock Z68 Extreme7 Gen3 (Updated BIOS to 2.??)
i7 3770K ivy bridge
650W PSU
Crucial 16GB kit (8GBx2), Ballistix 240-pin DIMM, DDR3 PC3-12800
Sata HDD 1TB
Optical Drive
Etc,,,,,,,,,

Could be one of a few things, but in if my experience is anything to go by, I'd be putting my money on your PSU being the problem matey...

Also, make sure both the power connectors are connected (easy to forget the 4 pin 12v rail for the CPU - done it myself haha...)

Thanks, ill give it a go and let you know

Could be dumb but did you connect the power buttons and led switches for the hard drives correctly? I have mixed up the power and reset buttons and led lights because it was hard to see on the mobo in which direction they should be connected.

I would also make sure to connect the 12v rail as well as the 24 pin power connector. If that won't work, it's most likely faulty psu.

So i checked all the extra pins and everything was plugged in correctly, also the little power button/reset/speaker etc pins were all in (i tried them one way then the other) but the type of board i have has the power/cmos/reset buttons actually on the board so i assumed it would work without those pins plugging in, anyway i think it could be a psu so im gonna have to save the pennies and get a new one, downer.

I will leave this open for now until i buy and try a new psu, then let ya'll know.

Any recommendations on a decent psu (not too pricey)?????

Always go with corsair or antec. Those are pretty good. How much power do you need ? Do you have another pc to see if your psu is really the issue ?

I have gotten a board that was DOA. It happens, albeit rarely. If you can get hold of a new PSU to try you'll know for sure.

So after a lengthy tutorial on checking my PSU with my multimeter i found out it works and is powerful enough to do the job so i'm thinking that the problem is a DOA motherboard, "DOWNER!", what makes it worse is that amazon only do a 30 day returns policy so i have to send it to ASRock which could be in Germany or China both of which have terrible postage facilities and will take a decade to get back to me just my luck.

Oh well, thanks for everyones help, much appreciated.

AsRock is an ASUS subsidiary. While tweaking my ASUS board, I had exchanges here with AsRock owners -- can't remember if they said anything about "startup" features, but my ASUS P8Z68-V Pro board had a "Mem-OK" feature that required you to push a button on the motherboard when initially starting up.

If your board had that feature and you didn't use it, I suggest you try before going forward on exchanging other parts.

EDIT/UPDATE: I checked your board's user-manual, and don't see the feature I mentioned. Did anyone think that maybe he has a RAM problem? Are you sure you socketed the RAM properly, in the proper slots?

Dunno how closely related my Extreme4 Gen3 is to your Extreme7, but the one and only time I had trouble getting my system to post was due to memory. It decided it didn't like being in the slot closest to the cpu socket... or maybe it was the slot farthest from the socket. In either case, I ended up having to take the sticks out and reinsert them, one by one. Never had an issue getting the thing to boot afterwards.

Long shot, but are you sure there's not a short somewhere? Something buggy between the mobo tray and the mobo?

It shouldn't be a memory issue. Like you I have an Ext4, but if the memory is installed in the closest DIMM arrangement
[CPU][X][][X][]

Instead of what it prefers
[CPU][][X][][X]

It still boots, will show an error if it has a monitor to show it on, and shows a error code on the 88... I think it shows the wrong one... but the point is it's not blank.

Even the Ext4 I fried (Fan power to PCIe bridge... whoops, lol) tries to show stuff on the error code display.

But... different boards, so hard to say... just throwing stuff out.

Iono. I know I'm not the only one who had that issue, I solved my problem by doing what someone else did. In my case, the fans would just spin at full speed and nothing else would happen. No image, no nothing. I was about to declare the board dead until I reseated the ram.

I'm using 4 sticks, though, fwiw.
