I've been having this problem for a while now but never connected it to the integrated graphics. I have a discrete card that I use, but I have dummy monitor set up on the integrated graphics, so I can take advantage of Intel Quicksync for watching movies. I have a 2500k that is currently not overclocked.
I used to get a lot of crashes during startup when I had Windows 7 if I started the system with my tv on. I never experienced any other crashes.
I recently wiped my drive and installed Windows 8. The crashes have been coming often during startup with the tv off and I have also experienced several crashes when I turn off the tv and leave the computer running. I'll turn it back on to a blue screen. Every minidump shows igdkmd64.sys as the culprit. It makes sense because the system is switched onto the integrated graphics. I have never seen a single crash with the tv on. =
I have used multiple drivers and the ones that come on the discs with Win 7 and 8 seem not to crash. From reading different forums, it seems that this started with later drivers.
I've done a lot of stress testing due to overclocking experiments with Prime95 and have never had a crash there except what was related to undervolting the CPU.
My next testing step would be to take out the discrete card and run just on the integrated graphics, but I don't want to do that if there's some alternative.
Here's what blue screen view shows:
