Question New custom built computer crashes in needy games


Dec 25, 2013
Hi, i have bit of a big problem. My custom built computer crashes all the time in graphicaly needy games.

My system:
Mobo: Gigabyte B450M DS3H
CPU: AMD Ryzen 7 2700
RAM: G.SKILL DDR4 16GB (2x8GB) Aegis 3000MHz CL16 XMP2
PSU: Cooler Master Elite v3
SSD: Western Digital Green 480GB
GPU: Radeon RX 5700XT

Before i built it, i already had this GPU in old system for couple of weeks. It worked well in there. Now the system crashes all the time. If i try to overclock something, it does more frequently.

The computer goes like in pre-shutdown state when it happens. Display goes black and keyboard and mouse LED turns off but the computer itself goes quiet but still works. Only thing that gets system back to normal is manually restarting it.

I have ran out of ideas how to fix it... is there a possibility that PSU is bad? Cause if i overclock it makes it more often.

Best regards.
