Hello everyone!

I've got a big problem on my Acer laptop, and I'm hoping the experts can give me a hand here:

  • Can't start Windows 10 outside of safe mode (reboots before sign-in appears);
  • Can't install a fresh copy/repair Windows 10, I get a Machine_Check_Exception BSOD.
  • Can run a prime95 stress test. Done it for at least 10 minutes at 90% CPU and RAM use without BSODs.
  • When booted (in safe mode with networking), using Chrome to browse, say Youtube, quickly triggers a Machine_Check_Exception.
Also, about a month ago I changed my CPU's thermal paste for liquid metal and cleaned its fan. My temps dropped dramatically, CPU from 90-95º C to 75-80º C and GPU from 90ºC to 75ºC.

My Specs:
Laptop: Acer Aspire V3-772G-9820
Processor: Intel Core i7-4712QM Processor,
RAM: 8 GB of DDR3L,
HD: 1 TB 2.5-Inch 5400 RPM
GPU: NVIDIA GeForce GTX 850M

    After extensive research I was convinced it was a CPU issue, so I ordered an I5-4210M from China (via Aliexpress) and replaced the CPU.

    Problem solved, indeed it was a faulty CPU.
