Palit GTX 650 Ti random blackouts, freezes, please help!

Hi.

The story:

Part 1 It's my friend's PC:

ASUS P8B75-M
Intel(R) Core(TM) i5-3470 CPU @ 3.20GHz
24GB RAM (2x8 one model + 1x8 other model)
PSU: 400W, 450W

msinfo: https://drive.google.com/open?id=13jVay-N8iacCbPYZY4TItd60XqVaspzh (not an audio file! Download.)

Didn't have any issues first. Had Win10.

Then they installed Windows 7 x64 (most likely unofficial pre-activated "build", don't know the details)

Getting random blackouts, followed by "Video driver stopped responding and was recovered"

Then they installed Win10 (also - unofficial build, and cracked it with KMS or whatever)
It worked very slow since they installed it: menu appearing seconds after select, app takes up to minute to open, etc (your usual "it's time to reinstall windows" symptoms)

With Integrated GPU, the system works faster than with 650Ti.

Killing Floor 2: sometimes it won't run at all, sometimes can only play like 2 minutes max - then blackout, freeze, error report dialog, logs say something like "Timed out while waiting for GPU to catch up"

OCCT: runs for 2 seconds then same blackout, or BSOD (VIDEO TDR FAILURE, nvlddmkm.sys)

GPU temperatures never get above 50 deg c


Part 2: I came to take a look .

Reset BIOS - no result.
Installed MSI Afterburner, touched the GPU overclock runner - it sticked to mouse cursor, moved when trying to release it - blackout. Hard reset - log in successful, but instead of desktop, black screen with colored squares (but the cursor is there) - something like this: https://imgur.com/a/K9OgV

Used MSI Afterburner to Underclock by 100 MHz (GPU), 150 MHz (mem) - same result.



Part 3: I reinstalled system:

Installed Win10 (official Microsoft ISO from their site, let it auto-update and download drivers automatically

Works much faster,

Launched OCCT Benchmark
After a few seconds: Same Blackout, this time - with some colored squares.

Just updated drivers to ones from NVIDIA site: no more colored squares.

Furmark: no blackouts so far, temp keeps rising up to 70 without issues. But then (about 2 minutes) blackouts, BSOD

OCCT Benchmark: same behaviour.

msinfo32 attached.


Thoughts: drivers? Or failing GPU?

With various OS setups and drivers, most likely video card or power supply.

Update:
They installed new PSU:
OCCT: significantly more steady picture (without these twitchy lags)

Updated GPU drivers to latest version (game ready whatever with gf experience) - install took quite a while, restart, win10 circles animation - then freeze, picture looks like this: https://imgur.com/a/Ff1Wc
After 15 minutes - logon successful.

KF2: Not fixed - blackouts.

So most likely it's GPU.



NB: PSU rated as "Tier 4" on Linus forums, but it's probably not an issue - I have the same Tier PSU, and so far - so good (5 years or so)

What power supply did you replace it with? Replacing a possible bad one with a low quality one is not much of a switch even if that same model works in another system fine. Test the card in another system that will rule out if it's the card or something with your system.
