System booting up, yet display and input devices are inactive.
System booting up, yet display and input devices are inactive.
In short, my computer stopped working suddenly, with the monitor, keyboard, and other parts shutting down. The fans were still running, but everything else seemed to power down unexpectedly. I tried simple solutions like changing the battery in the motherboard, restarting the PC, and turning it off completely, but nothing helped. Over time, I noticed some recurring problems starting a few days ago. My screen would freeze, headset would cut out, and the keyboard and mouse would shut off. Despite this, the lights and fans kept working. Once I touched a fan to silence it, it stopped working again. After turning it off and back on, the monitor wouldn’t start at all. I even tried removing the power cord and restarting, but the issue persisted—except for the fans and lights. The next day I followed the same steps and still faced the same problem. A tip came up suggesting replacing a "2032 battery" in the motherboard. I did that, and suddenly the monitor worked again. After setting up some BIOS settings, it functioned briefly. I resumed using the PC normally, playing games, but then it froze again—freezing frame, all systems shutting down except the computer itself. Now it keeps restarting after shutdowns, with no clear pattern. I built this PC about three years ago using high-quality parts: a 1080 GeForce graphics card, an i7 4-core CPU, a Strix Z270F motherboard (1151 socket), a Supernova 850W power supply, two 16GB DDR4 RAM sticks, a 3TB HDD, and a fast SSD for 500GB. I think that’s the main issue now.
