Actually there is new BIOS indeed, but I don't want to risk my warranty flashing BIOS while I have no experience in it. I'll save it for extreme measures. Thats interesting, I never thought that little difference in RAM timing could result in something serious. CMK32GX4M4A2800C16 isn't in the list, but on the other hand CMD32GX4M4A2800C16 is, base difference between CMK and CMD is different heatspreader design (CMD have a bit more expensive and effective heatspreader). So don't really think that is the case. Still if RAM was uncompatible with Motherbord that does not explain absolutely idle period of PC running (since February 2017 till August 2017) - I didn't have any issue or BSOD for like 6 months. I'm sorry for asking dumb question but what is speccy? Snapshot of BIOS settings? I'm sorry asking this but English isn't my first language.

By the way, you should read this link (your cpu is part of the kaby lake family): Major Hyper-Threading Flaw Destabilizes Intel Kaby Lake, Skylake CPUs (click). You could try to disable the hyper-treading (if you need bluetooth).

K kvizerad Member Joined Aug 8, 2017 Posts 18 Sep 17, 2017 #14 Bluetooth is enabled both in CMOS settings and Windows. I wonder if that solve the problem. Otherwice I'll just disable it. By the way, I tried to figure out specific conditions make BSOD appears. There is some common thing about all three cases of BSOD - it occured after PC was on for quite a long time (more than 10hrs). I'll let PC work this night and look if something happens.

I've installed newest bluetooth drivers - it didn't take any effect (BSOD continues to occur) I disabled Bluetooth in BIOS, but still I wonder if it could be hardware problem with USB adapter or onboard Bluetooth device. My PC is still under warranty but I don't want to RMA untill I'll be sertain that it is hardware issue causes BSOD.
