Unseen BSOD after shut down, PC doesn't power down
The problem:
PC doesn't power down, the fans continue to spin after the monitor blacks out after "Shutting down.." screen. But sometimes it does power down, but I have to wait a while (1-2 minutes I think). It used to shutdown and power down quickly before this happened in the past though.
Anyway if it doesn't power down I press (no need to hold) the power button and it goes off.
I didn't know a BSOD is there (as the monitor is out) until I turn on the PC the next day and got a "Windows has recoverd from an unexpected shutdown" dialog talking about a Bluescreen.
Discovery of problem:
About a month ago, my PC suddenly restart on shutdown. After getting that a few times I unchecked "Automatically restart" in System Properties->Startup and Recovery. Then it became as described above (the fans continue spinning and PC doesn't power down probably due to an unseen BSOD).
Trying to fix it:
Using the program Nirsoft BlueScreenView, it seem like the display drivers are involved. So having the latest drivers(285.62) at that time, I reverted to older versions to see if the BSOD still occur. Tried two versions backwards and the problem still occurs.
Also tried re-sitting the graphics card but to no avail.
Other than this problem the PC works normally, I can play games, surf and manage files as per normal. Though my DVD-RW drive is pretty much dead already as it can't seem to read discs now. Another thing, I have a TV card running on unsigned drivers but it has been working since my first installation of Win 7 so I don't think its a problem.
Please help me, thanks in advance.
About system:

- Installation age about 9 months, reinstalled early this year as 'systeminfo | find /i "install date"' tells me
