Random Shutdowns -- Can YOU help Fix what even WARRANTY CANNOT? (Lenovo Y50-70)

[Mitizaro]

OH MIGHTY FORUM!
OH DENNIS!
OH SLICK HAIR!

U are my last hope.

Basicaly my laptop Lenovo (Shitnovo?) Y50-70 has I7-4720HQ, 8GB DDR3 Ram, GeForce 960M 4GB, HDD 1TB WD 5400rpm.

Now the bastard started shutting down after 2 months. At first it was 1 per 3-4 days, then it became every day.

Once it got up to 2 a day i called my store and asked for warranty repair. 
They send it to the service and the mofos decide to change the whole motherboard. Ok
Of course when i received it back it STARTED SHUTTING DOWN AGAIN THE SAME WAY even faster this time (3-4 times a day).
I called the store angry and they told me to send it their way for their techs to see it personally (the official service they use is not in the main storeBrand itself).

They gave me a small laptop to do my work in the meantime (this is not a laptop just for pornhub, yo).

My small laptoop shut down itself too! I was worried my electric current at home might be the cause, but the shop called me saying it was caused by CyberFox browser (which i also installed on my replacement laptop). Cool. They send it back, i was happy that they replaced the thermal paste (and told me the FUCKERS FROM THE SERVICE PUT A SECOND HAND MOTHERBOARD on my laptop (reason -- money... welcome to Bulgaria)). Nevertheless with changed paste and all cleaned up and tested -- it was supposed to be as smooth as virgin schoolgirl's freshly shaved kitty!

Guess what happened? We all lived happily ever after watching pictures of Dennis? Nope!
The fucker started crashing again! In CS:GO... in Chrome... In file browsing.. Yep!
{ Notice that after i removed Cyberfox from the replacement machine i had no trouble. And my laptop used to crash NOT ONLY using browser, i was just too relived to think carefully when they claimed such simple problem and obviously easy solution. }

They asked if virus was possible -- i installed NOD32 paid version (my internet provider gives me 1 license) and MalwareBytes 14 days trial -- I'M CLEAN AS A WHISTLE!

I have NO custom programs. After the first warranty service i had RE-INSTALLED my Windwos DELETING the whole fucking drive, using official win 10 home, not doing any custom app removals or additional tweaks -- pure normal microsoft shit.
I had originally used Win 8.1 -- still the same.
Even under UBUNTU (had to put it for 2 days to prepare by USB flash with microsoft installation) -- it CRASHED using Firefox!
Ok i though the whole mozilla software was the problem so the last WIN 10 installation i have NOT installed JAVA and i used Chrome.
Still crashes like i already said!

The laptop has NEVER been moved from my table ( i KNOW it defies the idea for laptop but stfu, i hate desktops), i have NEVER splashed water on it. 
I have not even touched it with my fingers on the screen! I love ma shit! It was never hit, nor mistreated.
I paid to electritian coming home to test my electric current and installation -- i have PERFECT electrical score and equipment in the house (i had the most expensive German Relays it seems)

Let me DESCRIBE THE SHUTDOWNS:
I get event ID 41. The shutdown itself is RANDOM at RANDOM TIMES. It goes COMPLETELY out in a sec sometimes giving a loud pop from the right speaker.

The laptop DOES NOT GET HOT -- not any higher than 64degress Celsius.

Often it happens during normal file browsing or facebook browsing with 2-3 tabs! 

I have fixed my power options to have the min and max processor % to 100 at all times. Removed the SLEEP mode and hibernation. NONE works.

I have benchmarked and stress tested it using Furrmark, 3D studio MARK, passmark and one more torture shit -- i got up to 95 degrees CELSIUS -- never have been before and NO problem!

The laptop is NOT EVEN challenged by my usual activity so its not thermals for sure.

The only way i can explain it is either the CPU, GPU or BIOS.
Searched for this issue, other Y50-70 have reported similar shit and almost none has found solution or cause.
One user claimed to have it fixed with bios downgrade from ver 3.3 to 3.0, but i cannot find that version in the vast fuckin internet. Other users reported this did not work for them.

Now it is AGAIN in for warranty... but the bastards will reinstall everything, use Internet Explorer and then after 5 days of bare use call it "ok" and send it back.
I can post several pictures on ADD/REMOVE PROGRAMS of all the software i use (nothing is too special or non SUPER popular -- i dont consider Viber, Skype and Spotify for "unique" programs that are broken by nature, wtf..)

SOMETHING VERY POINTING -- Right now before i send it -- EVERY TIME I PLAY CS:GO the first time for that day it CRASHES on the 5th - 7th round. 
And i noticed something interesting which MEANS something but i dont know why.
I bet only YOU SMART LTT fellows will know what that is:

2 sec before it shut down i had visual, i had my character moving to the LEFT uncontrollably (all keyboard input was cut) and i had sound but everything was out of control and BAM - shut down.
 

The shutdown is SUDDEN sometimes with a cracking pop on the right speaker and it is COMPLETELY off. I then usually proceed to start it back up, rejoin my game and finis the WHOLE game (and even one more -- all competitive) without problem!

My theory is that since i have proper visuals and properly acting characters and eniviourment, it is not the GPU but the CPU that goes into some infintie loop/fuckmeimavirginError or smth like that. Maybe the BIOS causes it, maybe the CPU itself. 
It is VERY suspicious how it ALWAYS ALWAYS ALWAYS happens on the first play of the CS:GO for that day. 

Also in The Elder Scrolls Online which i like but just installed (they gave 3 free days) it crashed ALWAYS after 2-8min of play. On HIGH or LOW graphics it matter not -- just shutdown.

I KNOW these things matter, especially the last bit with the CS and the way it behaves 2 sec before shutdown... but only a super smart ninja or low-level programmer can answer that for sure. 
 

One thing is for sure -- i bet YOU people here are MUCH SMARTER than my warranty and shop fag00ts, so... My hope is that..
YOU ARE THE LAST JEDI LINUS -- MAKE IT COUNT, BABY!

Massive shot in the dark, but have they tried replacing or removing the speakers from the motherboard? Sounds like it may lie not with the motherboard, but with the devices connected to it. 

[Mitizaro]

No. But i have to notice that it has happened VERY often when the there was no music or sound being played...
Also it doesnt ALWAYS pop a sound when it turns off. It does it 1/4 - 1/3 of the times.

Not to mention that after HUGE or continious amount of music/sound playback i do NOT notice a connection to the shutdowns...

I thank you for the reply, nevertheless!

Could you download aida64 and show us all the temperatures? It might be that some sensor is messed up and reading insane temperatures so it shuts down

Is it too late to just get a refund on that laptop and get something else? At this point, it's obviously haunted.

Have you tried just doing a clean install, using the Media Creation Tool from Microsoft to get a clean ISO(Or better yet, switch your browser to Mobile using an extension/by using a mobile device, and access that same address, it will let you download the ISO directly)
After that's reinstalled, don't install anything else other than your drivers, Steam and your anti virus (NOD32).
 

See if you can go a few days without crashes, then install each software that you use often, one at a time, giving yourself a days or two in between.
Because it is possible that you have one piece of software that really doesn't play well with modern hardware/OS, especially if it hasn't been updated in a while.

 

Oh and while on the topic of Clean installs...
Where did you get your drivers after doing it? From Lenovo or straight from each manufacturers?
If you got them from Lenovo's website, that could be it, it's not rare that laptop manufacturers barely give a second glance to the drivers they release.

And if it's from the various manufacturers, there's a possibility you got the wrong ones.

As such, I would suggest you go on this site (Get the "ublock origin" extension first, use Chrome for this)
https://www.driverscloud.com/en/start

Scroll down a bit, under Offline Detection press the "Older Systems" button(portable version, no install needed), get the .zip, extract the content in a folder and run "MCDetection.exe", it will open a small window, on it click on Detect, let it do its thing, it will open up a summary webpage giving you all the info on your laptop, then click on "My Drivers" in the top menu.
The list of drivers provided is all your latest drivers straight from the manufacturers.

First off yes i install preparing my USB with the media creation tool. I have tried about 12 systems. 4-5 win 8.1, 4-5 win 10 and Ubuntu 16.04
This IS NOT A SOFTWARE ISSUE.

The fuckers at the store are being total jackasses and basically i'm 6 months deep (i still have warranty) but in bulgaria for a refund to happen they have to be unable to repair it. Now the problem is -- they can always just say "hey we repaired it" and when you get it back and it starts FUCKING CRASHING 15MIN after being turned on they will respond.. "Ah... impossible... you screwed it somehow! Ok send it again for one more month".

If they cant do it now i will try some legal ways to obtain my money back and get me an ASUS instead. ASUS made for Bulgaria are the best in terms of stability.

Also i barely have ANY software. I installed realtek audio drivers, nvidia drivers aand... yep thats it.

Also i use several main programs -- viber, skype, spotify, steam, LOL, CS:GO (my only two games) Chrome and Visual Studio (.NET developer, only a beginner though). No anti-virus usually, i installed it the last week to check for issues/virues. CLEAN BABY.
 

So basically i have BAREBONES system and get the best part -- like i said, 12min after getting UBUNTU installed i had it crash (a.k.a shutdown).

So i dont think OS has anything to do with it. Yeah cyberfox MIGHT have been buggy, but i'd guess it was simply more "irritating" my already in-born issue.

P.S - you know whats even more interesting? Before the last Windows installation i had NEVER crashed during CS:GO and now it was a "standart procedure" every SINGLE first-game for the day.

So it COULD be a bad HDD -- however according to the smart it is in GOOD condition, not seeing any bad sectors AAND i did Defragmentation in this last windows.

Thank you for the reply. I currently cannot since the laptop is in warranty for the 3rd time.
But i HAVE done that and i can tell you that NO temperature -- neither north bridge, nor south, nor GPU nor any base temp was above 65-66 degrees ALL TIME high. Usually it stays around 48-58 uner light load, and about 62 under a bit heavier (light multitasking).

Afterwards i did something for the first time since i have this laptop -- i played ULTRA HIGH settings elder scrolls online 1080p was about 75 degrees.
As i said -- it doesnt shut down even during stress tests which put it above the 90 mark... so i dont believe its thermal issue.
