I would do a fresh install of all your chipset drivers if you can. Honestly a clean Windows install might be a decent idea if that's feasible.
I somewhat doubt you're having hardware problems with a newish SSD, although it's possible. Slightly incorrect RAM speed settings in BIOS can manifest in weird issues like this too, although I'd think Memtest would stress it out enough to show this, and as you said it's passing now on the new sticks.
In terms of SSD/HDD testing software, I'd only use what the original manufacturer of your drive has available. Especially with SSD's, seems like they get misdetected and I wouldn't trust them for testing purposes. Regular HDD's that's less of an issue.
I've done a complete reinstall of the nvidia drivers since i already had the newest during the problem.
Iam now 3 days free from a bsod. But I don't cheer too loudly (Thats literaly translated from my language, hope its right)
If the bsod is coming back i post the dumpfile and i will try reinstalling windows.
Now im going to do some research about reinstalling chipset drivers.
I want to say it again, really thank you for your time and help.
I did wake it was about to enter the password then it happened.
So i searche for ntoskrnl.exe this online.
I saw a few forums that it is caused by gpu driver conflicts.
Last time when i reinstalled my nvidia driver i did it via the advanced install option.
Now did some reseacrhe on the good way to completely reinstall it.
I did use a driver unistaller to delete it completely and in safe mode.
A fresh install of windows should also fix this most of the time accoding to the forum, but not sure yet how to do that i will look into that.
