Issues

[Lethal_postbox]

I am on my first build. I have a Ryzen 5 2600, b450 aorus WiFi gaming mobo, 16g ram, and a gtx 1650 super. I built this a couple weeks ago and since then everything has been running perfect. Up until last night when I noticed that any time I tried to open a game or do anything that requires gpu load the fans on the gpu would @rev” all the way up and my computer would go to a blank screen before it restarting or me having to restart it myself. I’ve done just about everything. Disassembled and reassembled, re-applied new thermal on my cpu. Can anyone please point me in the right direction!? I’m out of ideas.
