The PC is not starting and the motherboard doesn't show any diagnostic lights?
I was using my PC and it restarted suddenly. After restarting, it kept working but shut down after about three minutes and I can no longer turn it on. I'm trying to figure out what's wrong. I have the ROG B550F Gaming Motherboard. The top left logo lights up when power is on, but the debug lights don't activate. Does this suggest a problem with my motherboard or how can I identify the faulty component? I've tried reseating RAM, booting without a GPU, and clearing CMOS by removing and reinserting the battery. Any suggestions would be appreciated!
Hi, sorry to hear your PC stopped working unexpectedly. Here’s a detailed list of the hardware components I’ve used with both older and newer systems. Swap the CMOS battery for a fresh one and disconnect the power supply while holding the power button for roughly fifteen seconds to release any residual charge from the motherboard. After that, remove all power cables, reattach them properly, reinstall the GPU, its power cords, SSD/HDD connections, and M.2 drives, ensuring every connector is firmly connected. Once everything is secured, plug in the PSU and switch it on. Wait a moment, then press the power button and observe whether the motherboard powers up. It might take a few minutes for the system to boot, as the board could be recalibrating RAM and cycling on and off before entering BIOS. A simple POST test involves booting the motherboard into BIOS with one stick of RAM in slot A1, ensuring your GPU is installed, and connecting an HDMI cable to display it on a monitor or TV. These steps have proven effective in getting PCs that suddenly shut down back online.
There are also individuals here who can assist with troubleshooting the issue. Possible causes could include overheating or overclocking problems leading to sudden shutdowns. I’m confident you’ll find a solution and achieve a successful outcome.
All the Best,
An old-school gamer and PC builder. Cheers.
My build has been around for about five years, with the exception of the GPU which I swapped two years ago due to a fault. The CPU is a 5800X, motherboard ROG B550-F, GPU is a TUF 3060ti, AIO is Corsair h100i Plat SE, RAM consists of Corsair vengeance rgb C18 at 3600mhz with 16GB x 2, the case is Corsair 4000x, and the PSU is Corsair RM750W.
Hello, this procedure might require you to repaste your CPU. Proceed only if you're confident with the steps or have performed it before. This is extremely important. Thermal paste should be reapplied roughly every four years, particularly if you engage in heavy gaming or demanding productivity tasks with your PC. If you choose to repaste the CPU, remove the cooler and thoroughly clean both the CPU and cooler surfaces using isopropyl alcohol. You might need to reinsert the CPU after cleaning. Then spread the paste in a way that ensures full coverage once the cooler is back in place. There are various methods for applying thermal paste; select the one that suits you best and delivers optimal cooling performance. Let me know if you'd like further guidance or have noticed other concerns. Please share the details. Thank you.
Are there any lights or sounds (like mouse, keys, hard drive spinning, fan) present? If yes, unplug everything except the GPU power, 24-pin and CPU connectors, and check if it powers up. You might want to use a low-power GPU to test if the GPU is causing the PSU not to start.
Thank you Popatim and DaleH. I trust your guidance will assist Shir0x with their computer problems. Cheers.
