Error 0xc00000e9 on Windows install; Mobo or PSU to blame?

When attempting to install Windows 7 on an older (2-3 years) system, SSD/HDD may not be recognized in the BIOS (but sometimes is in IDE mode), and installation fails at variable times with error 0xc00000e9 (I/O device not found).

The error occurs with only a DVD drive and a SSD (OSC Vertex 3, 90GB) connected to the SATA ports; however, the error occurs at different times during different installation attempts.

Memtest86+ runs overnight without errors, and the power LED on the SSD is on (sometimes I hear the DVD drive spinning down and then up again during boot). I've tried multiple SSD/HDDs and two DVD drives, but no joy. Anecdotally, is it more likely that the motherboard is damaged (AsRock Z68 Extreme3 Gen3), or the PSU is is giving out (NAXN 750W, powering mobo, the aforementioned drives, and fans)?

I'm working on getting a multimeter to test the PSU (I've tried several cables on different rails), but any advice is welcome. Thanks in advance!
