Hey,

I just got all the part for my new computer in the mail and I've assembled it all togheter, but the pc won't start.

I think I've pluged everything correctly, but the only thing working is some small lights on the to off the case.

- Cooler Master CM 690 II Advanced Black Fans: 1x 120mm Front, 1x 140mm Top, 1x 120mm Rear, Blue LEDs, 19 dBA

- Chieftec Super Series 650W PSU, ATX 12V V2.3, 80 Plus, Modular, 1x 6pin+1x 6+2pin PCIe, 6x SATA, 140mm Fan

- Intel Core™ i7 Quad Processor i7-950 Quad Core, 3,06Ghz, Socket 1366, 8MB, 130W, Boxed w/fan

- Gigabyte GA-X58A-UD3R, X58, Socket-1366, DDR3, ATX, USB3.0, SATA 6Gb/s, 2xPCI-Ex(2.0)x16, Revision 2.0

- Corsair XMS3 DDR3 1600MHz 6GB CL9 Kit w/3x 2GB XMS3 modules, CL9-9-9-24, for Core i7

- XFX Radeon HD 6870 1GB GDDR5 PCI-Express 2.0, 2xDVI, HDMI, 2xmini-DisplayPort, 900MHz

- WD Caviar® Blue™ 1TB 3,5", SATA 6 Gb/s, 32MB Cache, Dual Processor, 7200RPM

- Antistatic Armchain 180cm

This is my pc specs and I'm pretty sure I've done everything right.

Is there any way I can check if my motherboard is 100% working because I suspect it to maby be a little bit faulty.

Please reply.

Make sure you have the 24 pin and 8 pin power connections plugged into the motherboard.

And be sure you have the memory in the white slots only.

ty for response. but isn't the 8 pin realy a 4 x2 pin?

i've anyway tried both so, nice if you have some more tips

Is there an on button on your motherboard. If so unplug the front panel connectors..... ie on and off switches and use the one on the motherboard.

I didn't find any on/off switch on the motherboard, I think its really wierd that nothing else. but some small lights are working, not even the LED's or fans...

I have thought about this for the last 12 hours and I realy don't know whats wrong, its obviusly power in the motherboard and all the devices is powered, if anyone have had the same or similar motherboard and could tell me where all the small wires were supposed to be, I would be really happy for any information no matter how stupid...

Your motherboard manual should tell you that.

Even if some lights on your motherboard are working, the board itself might still be fried. I've had it happen to me. Seems like yours is DOA though, mine wasn't. My suggestion is to RMA it if the vendor doesn't have some sort of warranty on top of the manufacturer's warranty. If the vendor does (commonly a 15 day warranty), send it to them and they will replace it at their cost. Assuming its actually fried and you have everything connected properly.

Check if the CPU is placed properly, you might have a bent pin

Check the memory sticks are in the right slots, refer to the motherboard manual. I built a h55 i5 750 rig and missed that, put 2 stick in the 1st and 3rd, like on the old core 2 build, it didn't post

I've sorted it out

The problem was that the led, on/off switch etc. was not correctly connected the color coding was wrong and I finaly found out where in the motherboard manual the right "settings" were.

Thanks for all the help
