So currently I have a year old PC, and I think from start of this year my PC would just randomly shut down without any notices. It will shut down like everyday, and when it's worse it literally shuts down right after it loads into OS.

Yes, I did try to search on the Internet for solution, but so far it has done no help to the problem. I even posted some posts on reddit and stuff, but since most of the time I have recieved no replies, I have decided to post one here.

Here is what I have tried to do so far

  • ■ Adding fans. Craptons of fans and aftermarket CPU cooler incase temperature was the issue.
    ■ Removing the case cover
    ■ Running the Memtest+84
    ■ Reapplying the CPU thermal paste
    ■ Reinstalling the OS (Win7)
    ■ Upgrading to Win10 (Still waiting if helped or not)
I tried to run both modes in the memtest+84 (fail-safe and multi threading) and the fail-safe mode ran fine without any errors, but when doing multi threading mode it runs fine until test #7 and it says [Blocked move] or something like that, and the test just stops there. Not sure what this really means though.

I have also went to log eventer and found kernel 41 error which I found out it usually is the problem with RAM or PSU or software problems (or anything actually).

Here is the spec of by PC btw:
CPU - Intel i5 4590
Mobo - Asrock Z97 Pro4
GPU - Gigabyte GTX 770 2gb
RAM - Corsair Vengeance LP 16GB
PSU - EVGA Supernova NEX750G 750W
SSD - PNY XLR8 120GB
HDD - WD Blue 1 TB
OS - Windows 7 ([strike]Premium[/strike] Ultimate) x64

Also, someone in the other forums mentioned that the PSU has been proven to be inefficient, and might be the cause of the problem.

If I can't solve the problem in this forum as well, that I am going to probably buy fresh new PSU and RAM just to be safe.

I really appreciate any answers you give to me. Thanks in advance.

EDIT: I am going to upgrade to Windows 10, and see if that possibly can fix the issue.
EDIT 2: Done installing, installed fresh new drivers compatible to Win10, and PC haven't crashed after update. Will see more tomorrow.

FINAL EDIT: Fixed the issue... it was my MoBo power cable wasn't properly plugged in. If you're having the same issue I really recommend checking the cabling as soon as it occurs. It could be an issue with something else, but don't be a moron like me and just make sure everything is secure.
 
Solution
I had a similar problem, not identical. My GPU wasn't plugged in fully to the PCIE lane, maybe check that?
Also, go through your instruction manuals perhaps and check that you have plugged in all the wires..etc...

Sorry, but GOOD LUCK!
