Sager NP9876 BSOD problem

Hello guys,

I'm new to this community but I come here begging for your help. 5 months ago I bought a Sager NP9876 from XoticPC, I fell in love the same moment I watched that laptop, and happily started playing as well as using it for my HW (I'm a senior computer science student), anyway, after the lates big Win10 update my computer started to giving me BSOD, it was really strange since the error said: VIDEO_SCHEDULER_INTERNAL_ERROR, one which I'm not familiar with, so I googled everywhere for solutions, as well as started to pay more attention to details on my laptop.

The first thing I noticed is that the video card and CPU had crazy high temps, about 90 degrees Celsius each, and I thought this was the main problem, so I popped open my laptop, checked for tightened screws and tried again, but nothing, it was still heating like hell. Next I re-did the thermal paste job, and I successfully nailed max temps at 80 degrees stable, but my BSOD kept popping up eventually.

The second thing I did was roll back my video driver, but while doing it, my laptop BSOD again (didn't started in safe mode to do it, very smart of me) and I had to recover my whole OS and reinstalled the suggested manufacturer version, which actually helped a lot with temps, but not with the BSOD problem.

The third thing was contacting Xotic, twice. The first time they asked for critical events in the event viewer and it said as the source Kernel-Power, and as description, "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.". The second time I contacted them they suggested pretty much what I already did, but I provided them with my WhoCrashed log as well with one from the Even Viewer.

And finally to some of my conclusions. I think it might be related to the power brick or the internal transformer of the computer since the laptop wont BSOD nor the screen will show crazy colors from time to time when unplugged. It also might be a bad CPU configuration, when I went seeing in the Sager CPU OC app that sometimes it was working at 4500MHz I knew something fishy was going on, so I checked on my BIOS and found out that 1 core was working at 4.5GHz and the other 3 at 4.4Ghz, placed a 0 instead and the problem got worse, placed a 42, for 4.2GHz and it solved some of them.

To some insight on my laptop I got a Sager NP9876 with an i7 7700K, a single GTX 1070, a single stick of 16Gb of RAM (no errors were found here when I ran a memtest), a 250GB M.2 SSD from Samsung, a 1Tb HDD from HGST and another 750Gb HDD from Toshiba (which I installed to place Linux on it), Killer Network double Ethernet card, and all the quirks offered by XoticPC.

P.D.: Not the BSOD (of course) but the screen going wild problem happens also on both my Linux distros (elementary OS and Lubuntu).

If somebody can help me out here I would be forever grateful since this is my college laptop as well (gave my Lenovo Y70 to my sister) and finals with these issues has been hell so far. For WhoCrashed logs and the Event Viewer logs here is a OneDrive folder with them: https://1drv.ms/f/s!Asn4zRa7SjHLk2ArnW8n9wXqDKZS

 

Cpu doing 4.5ghz is its max turbo speed = normal. "0" in BIOS usually means auto which would be 42 under 4 core load up to 45 for single core.

Load temps of 80 are acceptable, depending on the load and fan profile. Worst case, Prime95+furmark = 80C is outstanding. In a non demanding game at 1080p/60 fps and max fans, 80C is not great.

Did you check thermal pads and contact when you repasted? They shouldn't be squeezed too hard under the heatsink when screwed down and at the other end they should show some imprint of the edges of the chips they cover. Check the dm3/km1 owners lounges for re-pad guides. With laptop gpus only having the one core temp sensor we just never know there's bad contact on other parts of the card until there's instability, or worse.

Try further lowered multipliers on the CPU, see if that at least gets your system stable.

But getting screen corruption on different OSes and a crash during driver install suggests a GPU hardware issue. Contact your reseller again.

 

Actually I'm really afraid of a hardware issue since I live in Latin America, and to send it back would mean I have to travel to the US and stay there until all repairs are done, thanks for the suggestions and will look into the thermal pads solution.
