Thread stuck in driver

Can someone please help me.

I bought a brand new PC (roughly £500), its got very average specs and sometimes when loading into a game I get BSOD (thread stuck in driver) issue.

I've updated graphics drivers. Even clean wiped them and installed them. Got new Nvideo driver detector to find other drivers to use (Thinks I'm up to date) Updated BIOS drivers.

I play a lot of other game on this new machine and I only have problem with LOL. I play D3, Civ 5 etc all fine...

I've been BSOD'ed out of 2 or 3 games this week which has understandingly led to remakes and Riot have punished me and reduced my draft priority. I'm disappointing a brand new machine has this issue with LOL and I get penalised for it. :(

Please help, Thanks in advance.
