BSOD when computer left idle

[scubudo]

I keep getting BSOD every few days with IRQ not equal or less than message. I have no new hardware or software. This did start shortly after my NVIDIA driver said there was an update, but when I ok'd the update, I got a message saying that the update failed. When I tried again, I was told that my NVIDIA was UTD. While I suspect that this may be what caused the problem, I really am not sure.
I initially attempted to restore my system to a point prior to the update, but that didn't seem to fix the problem.

Norton is a frequent cause of BSOD's. Please uninstall it and use Microsoft Security Essentials & the Free version of Malwarebytes, update and make full scans separately:

• Malwarebytes Free

   Note
