BSOD League Of Legends, Memory management error 0X1a

Heya,

Ive done a complete reinstall, I have reseated the ram, reinstalled all the drivers to the latest and disabled the dedicated videocard, now the pc works on the intel one without any problems.

but when I try to start up the dedicated one, then it suddenly blue screens when i play a game, so its definitely the nvidia videocard, perhaps the drivers are terrible and the optimus is really bad?

I'm going to reinstall the graphic drivers to an older one and basically try to test the drivers from there on upwards to the latest, and find out which one solves the problem.

Well I think its a success, Ive done a couple of things, let me start with the first one;

I did a clean reinstall on windows, afterwards I started to manually install every driver, and the intel integrated graphic card one I did from the laptop's manufacturer's website, and the dedicated videocard doesnt really matter, update it, lets say to the latest?

Secondly I reseated the ram (took it out and placed it back in).

Next I went directly into the bios (restart and press F2), there I switched off the dedicated videocard and chose only the integrated graphic card. I did this to test the integrated videocard, to see if there were any problems with it, after starting it back up and trying out LoL no problems happened, I could finally play games, although the fps was quite lower than using the dedicated one (which is obvious).
But now I was sure that it wasn't the integrated video card which was failing, but it was the dedicated one which forced the integrated one to fail (Optimus).

So this time I went back to bios (restarting and pressing F2 or whatever works on yours), and switched the graphic card option back to 'switchable'. Now I saved the settings and restarted the pc and another problem occurred: the pc would stick at a black screen. My fix to this was by reseating the ram again (taking it out and placing it back in again).

This time the laptop started properly and I was back into windows, what I did now was uninstall the dedicated videocard and its drivers (in device manager, right click the videocard and then click uninstall). Then restart the laptop again after finishing that.
Once the laptop restarted, I went directly into the dedicated video card's manufacturer's website (Nvidia) and downloaded a WHQL-driver, I think mine's 320.49? I'm not sure, but I just installed it and ran the .exe
Anyway, instead of choosing express install, I chose custom one, here I unchecked the geforce experience (note: I did not check the clean install) and I just went ahead and completed the installation.

I also downloaded another program 'Nvidia system tools', I installed this and opened up the control panel, here I accepted the agreement and changed only one thing: device setting > set it to custom > graphics clock to 650 instead of 672.

Finally I restarted the laptop and it seems to be working fine now, but the fps is now lower than before (normally 180 fps in-game but now its as low as 20 and occasionally it jumps to 100). I'm still going to search for the problem, but after I had done these steps the BSOD's have completely disappeared and I can play LoL. I am going to test a game that requires better graphics and see if that will run without any problem.

Anyway I hope this works for the people that read it.
