BSOD Windows 7 KERNEL_MODE_EXCEPTION_NOT_HANDLED 0xc0000005 ntkrnlpa.exe

This is my first post on here. I'm having an issue with a Dell OptiPlex 790 running windows 7 32-bit, we have many of these computers on our domain without any issues, just this one.

The computer will randomly lockup and then stop displaying video and wont respond. I have tried a few things already like checking the event logs, updating video and chipset drivers, running chkdsk and a few other things without any luck. Finally yesterday the issue created a minidump, please see below
