BSOD Faulty memory?

Ive been getting BSOD's for months now. every time i take it back to be looked at under warranty they say that its all fine hardware wise and theres nothing wrong with it.
It started constanly blue screening this morning so i have formatted and have a fresh install of windows 7 on with no updates and no drivers.
it then blue screened while i was out side. ive uploaded the mem dump file.
if anyone could take a look at it and let me know what they find that would be amazingly helpful.

Hi and welcome. Little doubt about what caused this crash. You were runnning winsat, and the video driver folded

I would re install the video driver
run a system file check to verify and repair your system files
dl memtestx86 and run it for several hours

Good Luck
