Windows 7: IRQL not less or equal BSOD while playing GTA IV

I got a BSOD while playing GTA IV saying something like "IRQL not less or equal". I also think it happened yesterday while GTA IV was idling, as when I returned to my computer it was back at the welcome screen where you log in. My computer is over clocked from the default 2.4 GHz to 3.0 GHz. Temps at full load are, on average for both, around 65 degrees Celsius. Not sure if the temps have anything to do with this though. The SF Diagnosis files are attached.

Thanks for your time.

Drivers

The following drivers need to be updated:

Code:

l260x64.sys                 Tue Mar 17 21:00:35 2009 (49BF74C3)

These drivers can be found by searching them in Google and then finding the associated software or driver. Finally, find the latest version of this driver or software and download and install it. Some of the drivers may also be found here (if the driver says 'Windows Update' simply make sure all Windows Updates are installed).

You should also update any other drivers you can think of including graphics, audio, chipset, SSD etc.

Your dumps indicate the presence of dtsoftbus01.sys, a driver associated with CD virtualization programs that is notorious for causing blue screens. You will therefore need to remove any CD virtualization programs such as Daemon Tools and Alcohol 120%.
