Hello. I build my new pc just a couple of months back. It has b450 Tomahawk, Ryzen 5 1600, Radeon rx570, 8 GB x 2 Corsair 3000 Mhz, 500 GB Crucial M.2 SSD. I put it all together in Corsair spec 05 box and powered it with corsair cx450 power supply. It was working better than expected but all of a sudden it started shutting down in the middle of a session. What I mean by shutting down is my screen randomly freezes to a solid color and then starts showing "no signal" message. I then have to force restart it from the power button. Sometimes it works fine for long hours, sometimes this happens in short intervals of time. I dont do much resource heavy work. CPU and GPU mainly remains below 10 percent mark. Would love to get some insight on the issue as I have no idea whats going wrong in my brand new pc. Thankyou very much for your time.
