Windows random crashes

[tibucci]

Hi everyone,

I have my Desktop PC since 2011, an Acer Predator G3600 my parents bought me, the specs right now are:

-Intel® Core™ i7-2600 quad-core 3.4Ghz
-Nvidia GTX 1050 TI 4GB
-500W Power Supply
-512 SSD + 2TB HDD
-6GB DDR3 RAM (3x2GB)

Everything except the SSD,HDD and GPU are the stock ones.

This machine had been giving me some problems for the last year, but nothing that was a "game breaker", sometimes it was slow and sometimes windows was throwing errors with the updater(I was running Windows 7), but the HDD inside had eight years so I figured it was that...

About 6 months ago I bought the 512 ssd(is a Crucial MX500) to replace my old OS HDD, after switching the ssd as boot drive my pc didn't turn off anymore. Windows would turn off correctly but the motherboard would stay powered(no disk activity). It was a fresh install of Win7 so I thought maybe it was a driver or something, so I cloned my old drive on the SSD but it didn't change anything. I tried to update to Win10 but it kept failing so I got a windows 10 license, from another pc that I converted in a linux machine, and installed that(fresh install) but the system still didn't shut down completely. I had 2 computer businesses "check" it and neither could find why the pc didn't shut down properly. If windows is on a HDD it turns off correctly even with the SSD plugged in as a secondary drive, but if windows is on the SSD it won't turn off.

In the end I gave up and after windows would turn off I just used the power button to shut it down completely. at least it was running much better than with the old HDD.

 

Last week I powered it on and after a while(10-15min of Minecraft) it completely froze: no mouse or keyboard response, screen perfectly still and even trying caplocks or numpad didn't turn on or off the light on the keyboard. Shut it down by pressing power button and rebooted I played Minecraft for 1-1.5 hours without any problem. but since then at random it freezes completely, sometimes I'm playing but it also happened with nothing running and just being on desktop, sometimes after 1 hour sometime right after boot.

No event in the windows log except that it rebooted after a "incorrect" power off.

Did a memory test(no problem found), a clean Win10 install, and a complete avast and AVG scan but it still does it.

 

Any idea what might be the cause and how to solve?

 

 

PS: Italian here, hope my English isn't too confusing...

Honestly I thought of getting a new desktop and retire this one since it's 9years old, but a new desktop with

-Intel® Core™ i7-8700x six-core 3.2Ghz
-Nvidia GTX 1050 TI 4GB
-500W Power Supply
-1TB HDD
-8GB DDR4 RAM

which I think isn't really that much better than mine is around 1200$ here... and I didn't want to spend more than a month a half of salary for a new PC that isn't even a real upgrade...
