I owned this PC for a while and it functioned properly. Recently I've been testing different GPUs across various computers, but this one is now unresponsive. It shows a black screen without any alerts or error messages. Setup details: Motherboard model ASUS Z170 Pro, CPU Inter Core i7 6700K, GPU Gigabyte NVIDIA GeForce GTX 1070 G1, 8 GB GDDR5 RAM, HyperX FURY 16 GB (2 x 8 GB) at 2133 MHz DDR4, PSU Corsair CP-9020098-UK VS Series VS650 ATX/EPS 80 PLUS. I've tried clearing CMOS, using another PSU, a different monitor, and connecting the GPU directly to the motherboard. After reseating components, the CPU and one RAM stick work fine, but the rest remain inactive. The board partially lights up and fans spin when powered on, suggesting it isn't completely dead, but it seems the motherboard might be failing. How can I confirm this?
