Looking for a solution for shutting down of PC while playing games

[bumba6540]

(Please pardon my English)
So I have a PC which I built in 2016. The problem is whenever I play any games, the PC just shuts down after 10-15 minutes. Thinking it happened because of gpu temp I opened the case and blew air from a standfan directly on the card and the problem went away, somewhat(but still it shutdown after playing GTA V, TW3 for around 3-4hours).
But now it escalated into a nightmare. I cannot even play POE Deadfire without the PC shutting down in about 10 minutes. I cleaned the dust, reinstalled windows, did whatever I could but to no avail. Please help anyone.
My system:
CPU- AMD FX 6300
GPU- ZOTAC GTX 960 2GB( PC shuts down when gpu temp is around 65-70C)
PSU-CORSAIR VS550 550W
RAM- CORSAIR 8GB 1633MHZ
MOBO- GIGABYTE 78LMT USB3

You should run something that can monitor the CPU and GPU temperatures while gaming.
I think Afterburner from guru3d.com can do that.

Check the CPU and GPU temperatures, but my primary guess would be that your power supply is dying, which is no surprise since it is such a bad unit. But before replacing it, one last resort is to run memtest86 to check for RAM errors. If your CPU and GPU temperatures are fine, and memtest86 does not show any RAM errors, then you should get a good power supply first and foremost.

Agreed, PSU needs to be replaced with a better quality unit.

i second that too, the psu needs to be replaced. First try using a different psu if you have a spare one and see if it fixes the issue. If not, monitor the temps using HWINFOhttps://www.hwinfo.com/download.php...

I'm guessing....the problem is while playing games there is shortage of power in the GPU so the PC keeps shutting down, is it?

Yes, maybe that or something more serious with the PSU.

Basically, the PSU is not providing stable power to all components, causing them to malfunction and the PC to shut down to protect itself from damage.
