BSOD At random times (F4 stop code)

[smhltn606]

Hi, I am running windows 7 Home premium 64bit that has been clean installed off a windows 7 recovery disc because my laptop came with it pre-installed with an activation code. I am using an SSD that has been secure erased using a parted magic boot USB, as before I had cloned my previous OS onto it, but didn't like that. My computer will occasionally blue screen at a random time (sometimes during games, sometimes during work) and create a crash dump. I have included the report created with DM-Log creator, please help, thanks.
