I just bought a new prebuilt gaming pc 2 weeks ago and it keeps randomly restarting like either every 10 minutes or maybe hours.

I replaced my PSU to a gold one ( bronze ocypus to gold silverstone 750w) but the restarting still happens.

After that, I suspect it might be my house electricity so I bought a UPS, did not work.

So what do I do now? It usually restarts itself during gaming. It does not show BSOD when restarting instead the screen just turns off and on while the pc fans are still on

Specs: rtx 5070 zotac, msi b650m WiFi, ryzen 5 7500f, silverstone gold 750w PSU, single stick 16 gb ram Ripjaws s5 DDR5,Kingston 1 tb SSD ddr5.
