Intel DQ57TM issue... randomly locks up in POST

I have a customer's PC here that we special ordered the parts. Their specs are:

-Intel DQ57TM motherboard
-i7 870 CPU
-2x 4gb Kingston 1333mhz DDR3
-80gig Intel SSD (latest firmware)
-1TB Seagate ES2 drive (passed full scan and DST)
-SATA DVDRW
-Sapphire Radeon 5570 GPU.

The problem they are having is that it will randomly freeze or lock up during POST. Either from a hard shutdown or automatic restart.

I've swapped out the RAM with 2gig sticks and it still locks up. All the hardware tests out OK.

I'm thinking it is a compatibility issue between the motherboard and SSD, but I updated the BIOS and the SSD has the latest firmware.

I download Inte's SSD Toolbox and that didn't help much, but I did confirm that the SSD passes their diagnostic tool.

I'm stumped, but I'm sure it's a compatibility issue, but wanted to see if anyone has any input on this and if they ever experienced this before.

Power supply?

Do you have the 4-pin PSU power connector connected to the 2 x 2 AUX12V socket on the board? And do you have the two DRAM modules installed to the two DIMM 0 (blue) sockets of channels A and B?

Oh. I tried different PSU and the problem still occurred.

I tried the RAM in different slots. I even filled all the RAM slots with 2gig sticks (to make 8gigs) and the problem is still occurring.

Does the problem occur using the onboard video?

I have not tried the onboard GPU, but the customer does require a beefier GPU and the quad i7s don't have GPU.

Swap out the videocard then and see if that might be causing your issue

I did swap it out but it was with the same GPU (make/model). When I get the machine back I'll try it with an nVidia GPU, not AMD.
