(video driver 75508 did not work, 75629 was not available)
I installed all possible to get win 7 drivers, as adviced on one of the forum posts for resolving key poblems, I downgraded os system to Windows 7 Proffesional, from my MSDN Subscription, deleting factory installed Win 10. After having struggled with Windows 10 for 3 weeks, the system still used 100% of CPU for some internal work not leaving user chance to do anything.I came into conclusion that this system is to heavy for this not very powerful machine.
