First of all, thank you for your response R2D2_WD. :) Check the new things i figured, and see if you can see something familiar with another similar issue you have seen! :))
I also figured out, that this problem occurs when i shut down the pc and then trying to turn it on. Both in sleep,restart and hibernation mode, everything works fine.. Its very strange, i was thinking if something with the initialization of the ram is the problem, when turning it on after shutdown. I will try to test my RAM into an other PC, and also try to find a working RAM to test it in my PC, but until then, any help will be perfect.
