Thanks for the screenshot! Yes I understand it, seems like written swedish and german are quite similar.
Everything looks fine.
Have you tested, what happens if you put your old 512MB back in again?
And what happens if you only insert one of the new memory-chips or maybe a mix of the old and new one?
Thre are several scenarios in my mind:
1. The new RAM isn't compatible to your notebook or to each other, though it should be. I know it sounds stupid, but sometimes even two identical chips won't work together. Maybe another combination works better. And with your old RAM installed everything should work like it did before. If this is the case, using other modules can solve this problem.
2. The new RAM is defective, either from the beginning or during installation due to electrostatic discharge. But the errors are not detected properly. Then it should work with your old RAM.
3. Your mainboard is damaged. Either it was before the upgrade (your boot- and chipset-problems may point to this) or got damaged during install (ESD again). If this is the case, every combination of RAM-modules will show the same effect.
To be honest, I'm at my wits' end. Try other combinations of RAM, if one of them works, option 1 or 2 is valid and other modules should solve your problems. Kingston and MDT are known to be reliable RAM-manufacturers.
