My girlfriend just bought some new parts for her computer. She got a Ryzen 5 1600x, 16gb of DDR4 RAM running at 3200mhz, and an ASUS Prime A320m-k motherboard. Her graphics card is a GTX 1650 Super. She got everything mounted, her dad helped her because she’s not very tech savvy. Everything turned on, fans spun, her wraith cooler fan spun, GPU fans spun, LEDs on the motherboard lit up, everything was working except for… no display on her monitor, and the USB ports weren’t working. They’ve tried everything. From switching things around to following the manual exactly. Remounted CPU. Thermal paste. CMOS battery. RAM. All of it, to no success. Could this be a faulty CPU? A faulty motherboard? When she plugs the HDMI in, her monitor recognizes it and says looking for a signal. But when it isn’t plugged in, it simply says no signal. However, no success still. Everything turns on, but no video display and the USB ports don’t work at all. Not even on her case. Any solutions? Never seen this problem before, and gave her all of my advice after years of PC building. Made an account on here just to try and find out what’s wrong for her.
