Windows 7 - New Win 7 Pro x64 PC w/Lots of blue screens

I just built a new PC for a user at work with the following:

Asus P7P55D LE
Intel i5 750
Rosewill RG530-2 Power Supply
Galaxy GeForce 9500GT (512Mb)
WD 160Gb
OCZ 2X2 DDR3 (4Gb total)
Lite-On IDE DVD ROM

Win 7 Pro x64

I am getting frequent blue screens and have several mini dump files.

Also - I have tried the latest nVidia drivers as well as rolled back to the ones Windows initially installed and it happens with both.

I am going to swap Power supplies between my machine and the new one to see what happens there, but in the meantime, thought I would post here.

Any ideas/suggestions?

More info, Power supply change didn't have an affect.

I swapped the video card to an ATI HD2600 Pro and with the base windows ATI driver, instead of blue screens, the screens would just go black and I would have to hit the reset.

I just updated the ATI drivers via Windows Update, so we'll see what happens there.

Try using a different brand of memory. i have heard some having problems with OCZ

The latest half a dozen are all crashes in low-level physical memory management routines. If you haven't already done so, I'd suggest running some detailed memory diagnostics tests (MDSCHED and/or memtest86).

Resolved!

I had everything set at auto on the motherboard. Looked up some info on the memory and it requires more voltage that the auto setting provides. Upped the voltage to 1.7 and it appears to be stable.

Thanks - Jim
