Specs: all new

GPU: Msi Vega 56
MOBO: msi b450 a pro max

Hello, I just finished up building my pc, and everything will post and I can launch windows and browse the web just fine. However when I try to run anything like Kombustor or a Game the card stops giving signal but the msi logo is still lit up and on my mobo the vga led is on. The card is not running hot at all, 40 degrees when I launch the application.

I got new drivers for everything, GPU, mobo, chipset, new bios, redownloaded windows, reduced the power draw to 80%, tried the other pcie slot, swapped psu cables . . .
Gpu still crashes underload, Any help
