I am offering my PC for sale. The problem is the screen is black, only the signal appears but nothing else shows up. The RAM and graphics card are guaranteed to be working, but I don't know about the motherboard and processor; one of them is likely broken. I suspect the specifications are: Graphics card: GTX1050TI RAM Total Capacity: 8GB Type: DDR4 RGB Speed: 3200MHZ Storage: 500GB Processor: i5-8500
