I have no idea what could be causing this.
BSOD can hapen due to numerous diffenrent reason. It can be hardware failure (RAM, hard drive, etc.), messed up drivers or something else.
Exact hardware and more detailed description of how and when BSOD occurs would help us help you.
Is your mobo an Asus brand? Apparently this is common with those.
The DRIVER error originates from a driver file.
You need to find the affected file. The blue screen should tell you what it is.
Then report back to this thread.
For the other shutdowns, it can be anything, but I'm willing to bet it can all be traced back to the driver error.
If the BSOD disappears too fast for you to catch the error message, check the Event Logs (do a search in your Control Panel to get there).
Mobo: XFX 680i LT
GPU: Asus GTX 460 768mb
CPU: Intel quad core Q6600
PSU: Corsair TX 650 650 watts
RAM: 6gb DDR2
The blue screens happen at random now but previously it happened rarely but started getting more frequent, then whenever I launched Rome 2 it would do it after about 5 minutes. Strangely now it has stopped but I think it will happen again. It's not a traditional BSOD, it just says "your computer ran in to an error and needs to restart " with a blue background and the error.
Hmm, it is not an Asus brand, and it did have a file at the end, but I can't remember what it was as it was a jumble of letters with .sys at the end. The next time it happens I'll note it down.
The only errors I can find are related to stereoscopic 3D nVidia drivers and this: The driver \Driver\WudfRd failed to load for the device SWD\WPDBUSENUM\{ac115600-a6fb-11e3-af9b-806e6f6e6963}#0000000000100000.
