The computer isn't starting properly.
The computer isn't starting properly.
Ryzen 5 1400 with 1400Gb RAM, GeForce 1060 GPU, 3GB VRAM, MSI B450m bazooka, 80 Plus B450m power supply, Thermaltake 500W, Adata XPG DDR4 2400MHz, 16GB RAM. My PC powers up but displays a black screen. The GPU fans only run for a couple of seconds. On the motherboard, the VGA indicator lights up, suggesting the GPU isn’t detected, though the boot light sometimes appears afterward. All case fans activate similarly to the GPU cooler and all lights. The monitor turns on automatically when I power on the PC, yet it reports no signal detected. I’ve already replaced the motherboard and hard drive, but neither of those parts seemed to cause the problem. I’m unsure what else might be wrong. I don’t have extra money to test other components. Any advice would be greatly appreciated. Thanks ahead. This PC was purchased from a friend who bought it in 2018; it had been running for about two months before issues started.
