While IRQL BSOD's are generally RAM related, the fact the address that crashed [0x000000D1] is VERY low (which indicates a HW problem) and the fact the USB driver [usbohci.sys] was referenced points to a driver problem of some sort.
I suspect the printer and related drivers are the issue however the pc won't stay on long enough for me to do anything. It boots then crashes again. I tried booting in safe mode, last known good configuration. Basically, I've done all I know to do.
