Windows 7: Bad Pool Caller BSOD

I have a Gigabyte P43 MB. I cannot successfully install Windows 7 or WinXP.
It has been giving me different BSODs and getting to different parts of the install before it BSODs.
I returned it to Gigabyte and they say they could find no problem.
Now I get the same thing except it only gets to load files and never gets into startup.
I get 0A, 24, 19, C2 BSODs
I have the MB sitting on my bench now, but when I first fully installed it into a case it did the same thing.

I have tried this with 2 CPUs, 2 Graphic cards, 2 PSUs, 2 HDDs, and memory right out of my P35 MB. All of the components run fine on the P35 MB.

I can boot to Hiren's disc, I can run memory test, I can find no problems - but I can't Install OS.

what to do???

What is the source of the windows disc that you are trying to install? Can you have am alternative DVD/ ISO? How old the motherboard and the BIOS version is?

Also, you may try to install Ubuntu, just to make it sure that it is not a hardware problem. Though usually a Bad Pool Caller is not a hardware issue, it is related with driver/ software.

This is driving me nuts. The MB was RMAed 2x. Both times they found no problem.
All the parts - memory, cpu, HDD, video bd - work in my P35 system.
The PSU is a new one. At one point I tried the one in my main system.

the bad pool headers relate to something in high memory which would indicate it is I/O on the MB.
0xFFFFFA8003658310. Maybe it is a BIOS problem.

They r going to replace the MB so I will see what happens with a "new" MB.
