NVSTOR.SYS BSOD when trying to do anything

I'm asking this on behalf of my brother who is having many issues with a new custom built computer, but this issue has me stumped.

The last motherboard we used quit on us in the middle of use. Computer turned off randomly cause of this. So we now have a Jetway 775GT1-LOGE and I was seriously hoping this would work without a hitch, but to no avail. With this Mobo we cant even get windows to start. I tried all the ram, used different ram from another PC, wiped the hard drive, tried to install vista 32 bit XP professional Windows 7, changed the IDE drive port on the motherboard for the CD drive, switched the SATA port on the mobo, the only thing I haven't done is update the BIOS which is only 6 days old from the one posted on the website and that's because it requires a floppy drive which we don't have. I am out of ideas. We have a computer that turns on and thats about it, we can get into the bios and change things. I even changed things in the BIOS that I thought would help and still no go. Someone help me out here please. I'm frustrated and out of ideas.

I haven't run memtest yet but we did boot up linux and browse the net. The nvstor.sys is an issue because the motherboard is an nvidia chipset mobo. This is a low end motherboard. I think We should just send it back the chance we get and try a new one.
