Thx for the reply. Have uninstalled netgear driver
and deactivated the marvinbus64 driver.
Have also uninstalled trendmicro and installed MS Sec essentials, full system scan with no results. Installed Malwarebytes and did a full system scan. Results; 1 suspicious file, which I removed/deleted.
My computer have now been up and running the whole day, with no BSOD's.
Seems that your recommendations did the job.
(PS! I will post back if it didn't work) :-)
