Build Advice Wont POST

A friend has built a computer and it is not POSTing.

The spec is:
Gigabyte GA-Z68AP-D3
Core i5 3570k
HD 6870
Corsair TX650
Crucial M4
Seagate Barracuda 1TB (If I recall correctly)

He is getting constant short beeps at boot, which according to the manual means a power error.

Any help on troubleshooting?

Thanks

 

Graphics card got power cables plugged in?

 

Yes it did have but I took the graphics card out to isolate the problem and its still beeping.

 

put the 4 way cpu power connection on? sometimes its easily missed

 

Yup

 

Have you tried with just 1 stick of ram in to see if it is that causing the problem?

The ram should populate the white sockets first.

Also check that 4-pin cpu power cable also plugged in.

We are assuming that the motherboards bios supports that IB cpu? Website says has to be F7 bios.

 

He ordered a Sandybridge CPU and Scan said they were out of stock and sent him the IvyBridge instead. I assume that they would only change it to something compatible.

 

Try the ram thing first - unless you have a SB cpu to try we won't know re. IB support as can't get into the bios.

 

The single stick of RAM didn't work.

 

Did you try it in a different ram slot just incase one of the ram slots is borked?

 

Nope still no luck.

 

This is a real long shot - but what happens if you remove the CMOS battery from the motherboard, wait a 15 secs, put it back in and try to start?

 

Do you know anyone else with a socket 1155 CPU? I think it might need a BIOS update to support the new Ivy Bridge CPUs

 

Fraid not :/

 

May seem like a stupid suggestion have you tried going into the bios and reset it to default

Try and have a look behind the motherbaord, take it out if you have to, maybe a standoff or screw is behind the board and shorting the board and the board is not posting due to a fail-safe feature.

Take out CMOS battery, unplug PSU from wall socket and then hold down the power button for 10 seconds then put everything back together and see if that works.

 

OK, we have graphics output working now, but it isn't accepting (wireless USB) keyboard input and the speaker seems to be still doing the beep every now and then thing.

 

What did you do to get it that far? Use a PS2 or wired USB keyboard. So you can now get in to the BIOS?

 

My friend said he moved the GPU to another PCIE slot. We have now tried a PS2 keyboard and still nothing. On power on you just see the Gigabyte splashscreen and the F12 etc commands to go into BIOS but it wont do anything.
