Hi! At the start I'll mention that I am an "IT guy" (actually IT student) so I have some higher than basic knowledge about the stuff going on with my computers but now even I am lost... I will start from the very beggining of my troubles - that might be a long story!
So, one day (quite a bit ago) I was playing League of Legends with friends like I did for over a year after purchasing my Y580 and the in-game "bug splat" error occured. It is not something unusual, it happens to people a lot in this particular game so I was like "meh, again they f*** up something with the patch". Then the system notification told me that "driver stopped working but has recovered" or something like that, which was a first time for me. I googled the problem but before I could read anything the screen froze and I had a first BSOD since installing Windows 8 (and I have it for a year straight now). It was IRQL_NOT_LESS_OR_EQUAL pointing at nvlddmkm.sys, part of Nvidia drivers.
I started doing obvious things - ran Windows in safe mode, everything was working fine. Then I removed Nvidia drivers completely, including registry entries and stuff. System loded in normal mode and was working - previously the blue screen was appearing before my Windows 8 login page even loaded. I managed to play games on Intel HD GPU and do my usuall stuff without any problems - as expected to be honest.
I did a memtest back then, also did it few days ago for 6+ hours without any errors. I also ran sfc /scannow and chdksk without errors if I am not wrong.
Then I tried installing various Nvidia drivers. No success. Next - I installed the drivers that came with laptop on CD. Quite old, 2xx.xx ones. The system loaded, I logged in all happy, but then when I entered Nvidia Control Panel the BSOD appeared again... I decided to format my drive and installed Windows 8.1 (about which I kind of forgot, so that's why 8.1 not back to 8 - I was about to upgrade anyway, so seemd like not bad opportunity - not perfect one I have to admit). Blue screen again, same thing. I did complete system reset, then started to install the Windows 8.1 drivers from Lenovo's site with Nvidia ones being last and... suprise, suprise, BSOD appeared before the installation even finished.
So then I tried disabling the Nvidia GPU with drivers running, it launched to Windows and no BSOD, but I think that doesn't change anything. I've read A LOT threads about those kind of issues, but nothing seems to be like mine to be honest So I left my GTX 660M disabled - I'm an IT student as I mentioned so I can't afford to be left without a laptop for even a few days, so I didn't send it to service yet.
Now the funny part - I was playing LoL on Intel card for almost 2 months now since the GeForce BSOD occured. And recently I installed Path of Exile, which gives me the IRQL_NOT_LESS_OR_EQUAL BSODs after 5-10 minutes into the game (even on lowest graphics settings)! :D (League is running ok on pretty high details... so probably not temperature related? I don't really know now...)
What would you advise me to do? Shall I run all system files checks and chdksk again? Is this software or hardware issue? I'd just like to fix it if it's software, but I tried SO MANY things already that I'm closer to saying it's hardware stuff, but maybe you guys will be able to help me and maybe it will be a software issue - so help me God! :D
I'm attaching my minidump folder zipped, I will appreciate ANY help, thanks a lot in advance just for reading my story, thanks even more if you will try to help me!
