Windows 10: Laptop randomly freezes without bsod or dump

Hello, i need some help with an issue ive been having since a while. My laptop *MI LAPTOP PRO 15 MX250* in the past months keeps crashing every 5/10/15 minutes, randomly. I cannot find the source of the problem. Formatting hasn't solved the issue. The laptop just freezes without a BSOD or making a dumpfile. If the audio is on, it keeps grrrrrrrring until i have to force the shutdown. Can you please help?

:)

 

Windows 10 freezes randomly

I had already tried turning off fast startup, to no avail.
Will look at the list you provided, thanks. Hard to do when computer freezes on the Windows loading screen though. *Biggrin

I had tried that as well... no result.

 

BSOD and freezing

Yesterday I started up my laptop from hibernating and it freezes, after restarting several times I get a BSOD which freezed on the BSOD one time.
After restarting again the laptop freezed at the Welcome screen.
I have had the freezing before, it was gone for about 2 months.
I did not install any new hardware.
Now it seems to run fine again.

But what is causing the freezing and the BSOD?
I bought this laptop last January.

 

Multiple 0x0000009c BSODs on Windows 10 Lenovo Laptop

Symptoms:

• Windows 10 Pro BSODs randomly (after freezing). I have almost 12 identical dumps (attached).
• There seems to be no pattern to it but sometimes it happens when the machine is idle.
• The machine just hangs and then eventually reboots -- most of the time I don't even see a BSOD screen, it just goes from a frozen screen to reboot and the dump is generated.

Steps Taken With No Success:

• Ran full memtest with no issues.
• Clean Windows reinstall.
• Changed from HDD to Crucial SSD.
• Updated BIOS and drivers to what I think are the latest (manufacturer website).

Important System Characteristics:

• Lenovo Z70 laptop with dual Intel 5500 and nVidia GeForce 840M graphics cards
• Virtualization technology is turned on in BIOS in order to run virtual machines
• The BSODs stopped for a good while and then started up again quite frequently lately. I haven't been able to pinpoint any changes in how I use the machine.

Most of the dumps seem to point to intelppm.sys --I'm not sure where to go from here.I have attached the output of the information DM log collector. I have gone through all the files and sanitized them to remove any sensitive personal information (according to me) but that shouldn't affect the integrity of the information.
