Try a reset from within the BIOS first. Far easier for a start.

Has this resolved the issue? I'm having the same issue currently on an Optiplex 360 that is brand new out of box.

I am having the same issue with an optiplex 360 that has been working fine for months until we moved it to another user. It has a postage machine and a couple other usb devices attached. Dell has replaced the memory and mother board from warranty and i removed the extra video card. It still gets a blue screen randomly that says memory parity, only once every few weeks or over a month. Reboot and it seems fine?

A laptop or notebook is a portable personal computer with a clamshell form factor, suitable for mobile use. Although originally there was a distinction between laptops and notebooks, the former being bigger and heavier than the latter, there is often no longer any difference. Laptops are commonly used in a variety of settings, such as at work, in education, and for personal multimedia. A laptop combines the components, inputs, outputs and capabilities of a desktop computer, including the display screen, speakers, a keyboard, and pointing devices (such as a touchpad or trackpad) into a single unit. The device can be powered either from a rechargeable battery or by mains electricity from an AC adapter.
