Computer Turns itself off or restarts without any error/stop code

[BlazingAngel]

Hello. 

 

I have an old PC

       Graphic card: Nvidia GTX 750 TI

       Operating System: Windows 10 Pro 64-bit (10.0, Build 19042) (19041.vb_release.191206-1406)
       Language: English (Regional Setting: English)
      System Manufacturer: Gigabyte Technology Co., Ltd.
      System Model: GA-78LMT-USB3 6.0
      BIOS: Award Modular BIOS v6.00PG (type: BIOS)
      Processor: AMD FX(tm)-6300 Six-Core Processor              (6 CPUs), ~3.5GHz
      Memory: 12288MB RAM
      Available OS Memory: 12270MB RAM
      Page File: 8759MB used, 8533MB available
            

I recently tried upgrading to a GTX 1650 Super which i ordered from amazon and installed myself. I had to get a HDMI to VGA Converter since my 900 P Monitor doesn't support any of the ports the new GPU has. After installing the drivers the system was running fine until i put stress on GPU by starting Destiny 2. The game loaded but soon as i was in the middle of a strike my whole PC shut down and restarted without any BSOD/Stop code. And before anyone suspects my PSU, its a 600 Watt Gold PSU which is only 3 months old. I tried with other games and even a software called fuhrmark and every time the GPU was taking load my whole system shut down/restarted by itself and sometimes kept looping restarts until i unplugged it. Works fine now after i put the old 750 TI back in. Sent my card back to amazon for replacement. Any solutions ?

how are the temperatures? if they get to a certain high, the pc will shut itself off or reboot.

It sounds like the problem is the PSU, but it should be enough 600w...

I would have limited the power of the GPU and see if it does the same, and if it does the GPU is faulty more likely.

Anyway, you can RMA both things xd. When you get back the 1650 form amazon you will know what is faulty and if you should change the PSU.

I got back replacement today. Same problem, but this time its just shutting down with my sound output going TRRRRRRRRRR and not re starting when i put stress on GPU. CPU is running at 78-82 Degrees with my 750 TI (Idle temp around 60) and it always has for 3 years even with new cooler. But my PC has never completely shutdown without any stopcode/BSOD until i tried putting in the 1650 S.  I have Zebronics ZEBPGP600W PSU. I has 2 PCIE 6+2 pins and i tried both of them to rule out any bad cables. Pls halp
