Issue is happening on 2 computers, identical errors, both identical hardware so hopefully narrowing it down on one will lead to the answer on the other.
Windows 7 Pro OEM x64, maybe a month old, I believe it came with Windows 8, I'm not 100% sure the circumstances but it got reloaded with Windows 7 Pro. Issue seemingly happens at random for both users. Items plugged in for each user are a document scanner, beyond that just wireless dongles.
I've tried updating Chipset drivers as well as Video drivers. I ran memtest (x86) and it went through a couple passes without issue. I just did this today, but I have a feeling it probably won't help. I'm out of ideas at this point, so I've come here.
