Can not get my motherboards to work in PC

I have upgraded my PC with a DFI lanparty an AMD 64 3000+ Enermax 600 noise taker, OCZ memory and a cheap PCIe graphics card. I could not get it to boot up so RMA?d the board back to DFI who sent it back but it still had the same problem of not even coming up on the monitor. Today I went and bought an Asus premier and fitted that with the same outcome nothing. All the fans start and the led comes on on the board and the disks sound as if they are starting up ok. I have tried some Corsair memory I had lying around and then tested all of the voltages on the various power supply connectors, all seem to fine and in tolerance no low volts all slightly over. Has anyone any more ideas, if the CPU is US would it have this effect? This is really bugging me now as its over 6 weeks since I started to build it and I need it working.

Thanks
 
I had the same problem, everything powered on but no video and no BIOS beeps. Tried a new CPU and I was off to the races. Try booting with no CPU and see if you at least get BIOS beep codes. I you do get beeps without the CPU but not with the CPU, its probably the CPU.

Try it outside of the case, there's a good chance you're shorting the board on the case.

definately worth at try; that is what happened to me when building current rig.. had one or two standoffs in wrong position and shorting board..
 
Mark and Azzy64,

Booted just fine out of the case! Thanks for that. Do I need to put insulating washers between the MB and the standoffs that the screws go through?

Thanks again

Check the rear USB, Firewire and network jacks to make sure the springy finger things on the I/O shield aren't falling into the ports and shorting them out.

Also, check whether your case has a standoff in the location circled in red in this image, and whether your motherboard has a hole there. If the mobo has no hole there, then remove that standoff from the case.

That's exactly what you need to do, I put the little paper washers both below the board, and above the board, so it sandwiches the board between the screw and mout, like this:


screw | washer | motherboard | washer | case

Never had that fail me yet!

Good luck!
