Reinstalled of Windows (and reinstalled of vegas)
Reinstalled graphics drivers (12.8,13.1,13.2 beta and 13.3 beta)
memtest86: 4 passes, no errors (but will run it overnight tonight)
Other things which could help narrow it down:
Vegas has been rendering very slowly (when it works), no settings difference, but OpenCL seems to not be working now - it runs at almost the same speed as my laptop rendering!
Does anyone know what's going on?
Thank you for your time.
p.s: Sorry if this is in wrong section, I don't know what it would come under seen as it could be a hardware problem or software/drivers problem.
[EDIT: Added error code.]

Ok, I tried that before, and I've done it again (first time it didn't work, put me back to original windows drivers for whatever reason), and it seemed to let me back into Vegas, although loading a project it still froze me, but without a blue screen, it was more like a system-wide crash, with no errors at all. mouse stopped, nothing worked, although I could hard-reset.
I've now hopefully fixed the problem (I just deleted the old projects and started new ones) and I've not had the freezing, or blue screens since. Thanks for all the help!
If the old projects were done in an earlier version of Sony Vegas or a different video card or different PC then problems as such might occur. Also, I just noticed a reference to the word "laptop", is this a laptop you are using?
