Hi everyone,

I've just re-built my PC with MSI B450 Tomahawk Max mobo and Ryzen 3 1200 processor and I'm getting a solid CPU red light on the boot. Also I'm not getting any signal to my monitor, only black screen. I'm using a HDMI cord which worked fine with the monitor earlier, which eliminates that possibility. I've checked everything is plugged in OK, PSU is good, and I've checked the CPU several times, no bent pins, all seems fine.
I've tried CMOS and bios flashback, and currently, my pc successfully boots, and everything seems to work fine, but it keeps randomly shutting off. Sometimes it boots for a while, sometimes there is this CPU red light and black screen again. I don't know what else could I do.

CPU - Ryzen 3 1200
GPU - GTX 970 4GB
MOBO - MSI B450 Tomahawk Max
RAM - 16GB G. SKILL RIPJAWS V (3200 MHz)

Hopefully someone can help me with this,

Thanks
