Random PC freezes 2

I cleaned my pc today. It has been a year since i last cleaned it. There was some dust in the fans but i have seen it worse xD. After i cleaned it i runned two tests with FunMark in 2 resolutions. I am attaching some screenshots i took

I don't believe the freezes are related to the gpu temperatures. When i runned the tests the fan was spinning very fast and it was noisy, i have never heard my pc making that sounds.
When i get a freeze i usually have only Google Chrome and Skype running, so my gpu is far away from reaching it's limits.

The past few days i didn't experience any freeze so i didn't check the older drive or the clean boot process. Today i experienced the mini freezes effect explained in a previous post. So it happened after i used a script in firefox. The scripts name is hommk gold (HOMMK - Gold Finder - by Dragon Azur) and i use it in a browser game i played. I realised that most of the times the freezes occured, they occured after i used this script. Since the last time i used it i didn't have any freeze, but after 2 minutes after i used it today the freezes occured.

So can this be a coincidence or not?

Today i had a freeze and my pc wasn't responding so i manually restarted it. After i restarted it a message popud up saying i had a bluescreen, some useful info about the freeze and some useful files. By this freeze a minidump was created. I am attaching it

i am still getting the error when i run the sf diagnostic tools at minidump. should i run and send you the results of the other tests of sf diagnostic tool?

i am attaching the results from the sf diagnostic tool. The minidump test wasn't done again, but i have posted the minidump file 2 days ago in the Desktop.rar
