Hardware Lockup w/graphical glitch

I have been having hardware lockups with my Arch system since I installed it on this (new) machine. Until today I haven't been able to reproduce the lockups and there was never anything in errors.log/elsewhere.

The screen freezes, I can't move my mouse/toggle capslock. Nothing works, I have to reset with the power button. Occasionally I will get graphical glitches on the screen (note, I have a 2 monitors with a virtual desktop size greater than my actual screen size, so graphical glitches could be occuring with every crash and they are just off screen). The glitches are always rectangles with scrambled noise-like green/black pixels if that matters.

Memtest ran for 16 hours without errors.

I have tried downgrading the kernel and nvidia drivers (I'm using proprietary nvidia drivers, I read on a thread that someone had solved a similar problem by downgrading). Still getting identical crashes.

Today is the first time I have successfully been able to reproduce the problem. It happens when I try and print (using lpr and CUPS) to a windows shared printer (using smb). The crash happens shortly after I run lpr (lpr returns). I only get this problem when using the Gutenprint drivers (Epson d68 if that matters). But the problem is identical to what will happen daily, seemingly at random. I say random, but sometimes I can go for 7 hours without a crash and then it will crash twice in the next hour.

I'm posting here because I finally have something to show in the logs:

Feb 11 15:47:55 troll kernel: pci 0000:00:00.0: BAR 3: address space collision on of device [0xe0000000-0xffffffff]
Feb 11 15:47:55 troll kernel: ACPI: I/O resource piix4_smbus [0xb00-0xb07] conflicts with ACPI region SOR1 [0xb00-0xb0f]

^^ is the last thing recorded in errors.log before the crash. ^^

Is this the cause of my problems? I do not understand this error message, but from my limited knowledge it would seem possible that an address space collision is causing my graphical glitch?

I can post other logs on request. I'm (perhaps naively) optimistic that now I can reproduce what seems to be the same bug, and that I have _something_ logging, that a solution can be found for this problem. However I'm clueless as to what to do next, so any help would be much appreciated. These random crashes have been a constant annoyance for far too long.

Thanks
