First time PC started, then powered off to install a fan, restarted and again powered off, no screen or BIOS displayed.
Hello, this is my first time assembling a PC from scratch. I followed the instructions carefully, powered it on for the first time, and the BIOS displayed correctly. After turning it off to install extra fans and organize cables, I restarted it. Now when I power it up again, the display doesn’t appear at all. The LEDs flash quickly initially before gradually slowing down, but there’s still no screen visible.
The components listed are: Asus B660M-A i5-12400F GTX 1650, 8GB Super SSD, 2666MHz RAM, NVMe SSD, 500GB.
Can you help me fix this issue? I’m really disappointed I turned it off after the first boot.
Begin by holding the power button down while keeping the AC power disconnected from the PSU. If nothing changes, perform a CMOS reset using the pins on the board. Clearing CMOS requires disconnecting AC and briefly connecting the CLRTC pins together with a screwdriver. Check the motherboard’s LED indicators for their meanings.
I attempted to reset the BIOS by shorting the CLR CMOS pins as instructed in the manual, and also took out the CMOS battery which was difficult to locate and remove due to the heatsink obstructing access. Following their guidance, I reset the motherboard, but it didn't work. The blinking light initially stopped recognizing RAM, then slowed down after a few seconds, and eventually decreased further over time without stopping. I'm concerned about potential damage to components and want to confirm the processor is still intact.
Replace your parts such as the CPU, GPU, and RAM. (If you're unsure what this involves, it means removing all components from the motherboard and reinserting them.) Adding a fan seems unlikely to cause the issue, but verify your new fan connections. Inspect your PSU cables to ensure they’re not damaged or disconnected. Typically, you’ll need an 8-pin CPU, a 24-pin M.2 slot, a 6-pin GPU (the 1650 model uses a 6-pin), and a SATA power cable for HDDs or SSDs. I suspect the problem isn’t a corrupted BIOS, but it closely matches signs of a faulty BIOS. When you powered down your PC to install a fan, what method did you use to shut it off? Did you press the power button, click the power button, unplug the PC, or cut the power supply? Hopefully, your system will run smoothly—it’s a solid budget build and still performs well!
