BSOD whilst watching videos online. Legit Windows7 and plenty of RAM

Hello there,
Firstly thank you for even clicking and secondly, my problem is as follows:

A few weeks ago I completely rebuilt my custom made rig. I used a legit copy of Windows 7 and everything was working fine.
I was then prompted to update windows 7 with about 80 different updates through Windows Update.
I installed these all including SP1 and that's when the problems started.

My computer restarted randomly whilst I was doing a lot of different tasks. I immediately went into safe mode and restored back to the point before any of the updates had been done.
This happened on my last config of my PC and I didn't not want to end up down this road again.

A week or so later and my friend tells me to watch this link as I am a "Dexter" fan and all that; Early_Cuts_Chapter01_Alex_Timmons_WEBRip.mp4 | PutLocker
When it has almost loaded my PC restarts randomly.

Now I followed the thread before making this thread, about how I should DL SF_Diagnostics_Tool, I clicked grab all "after right clicking run as admin" and it said there was no dump to find, and then an error was displayed about the Event Log.

I have got my BSOD to set up a Small Memory Dump (128KB) should I change this?

All the drivers are up to date as well, I am just not sure why it is doing this and why Windows used to crash after doing updates...

Thanks for your help,

Rhys

Just clicked on the video link to recreate the BSOD to try and get a successful dump and the **** works :@ I hate PC's however I feel this is not an issue that will simply go away, I am sure this will happen again soon...
