Hello

I’ve been trying to get help from other forums but no luck so far!

For the last three months my computer has been freezing after about 20 minutes of gaming (heavy load). Before it happens, for a minute or so, micro stutters appear. When the crash happens the system freezes (ping goes up but wind and other game elements still move for 3 seconds or so), the monitor also freezes, and system becomes unresponsive (CtrlAltDel or any other combinations don’t work) but doesn’t power off (RGB is still lit and the fans keep spinning). If after that I want to use the PC again I have to manually force shutdown with the power button on the case.

This still happens in clean boot so it isn’t a software fault (in addition, to prove that, I have completely formatted the M.2 SSD with a new Windows install, updated drivers and BIOS.

Computer's RAM is brand new (about a week old), CPU temp while gaming is under 60C, GPU temp. under 70C, and for the M.2 SSD CrystalDiskInfo says healthy 96%.

How can I determine the faulty component and what should I give as an explanation for warranty (all have about half a year left) ?

Can it be a GPU/PSU issue?

Specs:
CPU- r5 2600 (w stock cooler)
GPU- MSI gtx1660ti VentusXS
RAM- 2×8gb XLR8 3200mhz 16cl
MOBO- AsRock B450M pro4
PSU- EVGA 600br
Case fans- 3 for intake, 2 for outtake

All parts except RAM are 1.5 years old!

Thanks

Since the temperatures are fine, the relatively low-quality PSU would be the next suspect.
So I ran Heaven Benchmark (on extreme settings) again to check the temp. again (today is a bit hotter outside so the temp. are higher)

To not risk not getting the footage I split it into three parts (actlly 4 but the last one doesn't let me save after the crash occurred):

This time after the crash the screen turned black and after restarting it didn't want to boot up correctly, had to press the restart button once again.

Is there something these videos uncover?

That would be consistent with a power supply issue and possibly some minor data corruption from the sudden power-off which temporarily put a wrench in the works.

With this GPU -- mid-range GPU, not particularly power-hungry but does need supplementary power -- I'd go no lower than 550W Tier B from this list.


If there's a chance that you'll upgrade to a high-power GPU like the higher-end 30 series GPUs which result in huge power spikes, then Tier A at least 750W.

Yesterday switched out with a new psu (Deepcool DQ750-M-V2L 750W) and it crashed again!

So only thing left that could be causing the problem is the GPU?
