Blue screen crash

[afrikanac]

Hi, I need help with my blue screen error, what`s causing it? It usualy happends when my lap top is idle longer than 10 mins.
I`ve added attachment with my dump log and perfmon report.
I also run RAM and hard drive tests, and there are no errors.

Please remove any CD virtualization programs such as Daemon Tools and Alcohol 120%. They use a driver, found in your dmp, sptd.sys, that is notorious for causing BSODs. Use this SPTD uninstaller when you're done: DuplexSecure - Downloads
You can use MagicDisc as an alternative.
