System shuts down repeatedly when starting up, following the BIOS sequence.
I own an ASUS ROG STRIX B450-F Gaming II motherboard paired with an AMD Ryzen 5 3600 CPU. When the system powers on, it displays the ASUS ROG logo followed by BIOS instructions, then shows the Windows 10 logo briefly before restarting. I can enter the BIOS without issues but cannot access any other operating system. Attempts to boot Windows 10 or 11 USB drives always result in a quick restart shortly after. The Q-LED blinks but remains off. I've tried cleaning dust, replacing the graphics card, reseating RAM, updating BIOS, clearing CMOS, removing SSDs and HDDs, and booting from a USB drive. Any assistance would be very helpful.
Check if your motherboard supports exporting the current BIOS settings. Consider backing up the BIOS beforehand and then testing resetting to defaults or clearing the CMOS battery, since some boards retain power. You mentioned you cleared the CMOS, but it’s possible the board still holds residual charge. Ask if everything in the BIOS was properly reset after clearing and whether the system attempted to boot into Windows before failing. Also, inquire about any BIOS or firmware updates you applied before this problem started.
I used various USB drives during each attempt. A Linux drive didn’t help and kept restarting. I unplugged it, removed the battery, and held the power button for 30 seconds. I also reset the BIOS settings. This computer was made about a year and a half ago and was functioning properly just a few days prior. Appreciate your advice.
I'm considering switching to a different PSU or MOBO if you have one available. You might also borrow one from a friend. I'm leaning toward the motherboard. Are there any lights on it that show its status? I checked the manual, but nothing listed. It seems to use beep codes during reboots—does it emit any sounds? You might think it's because a drive is trying to draw too much power from a failing PSU, or the motherboard isn't delivering power properly. You could check for damaged capacitors or other signs of damage on the board. You can also inspect the PSU grills, but I wouldn't recommend opening or handling it yourself.
It hasn<|pad|>, didn’t restart while I was in the BIOS. No operating systems can boot. Temperatures seem normal. Only mouse, keyboard, and monitor are working. I cleared all drives except the USB I tried to use. It’s completely quiet except for fans running. The Q-LED lights blink once and stay off, suggesting it’s not a CPU or RAM issue. I’ve seen two old boards fail due to bad capacitors, so I checked that first. Everything appears okay. I’ll check if I can find a spare power supply nearby to try again. Thanks for all the help! Edit: I’m giving up on fixing it now and ordered a new motherboard.
Consider setting ideal configurations in BIOS and re-flashing them.
I attempted that, but it didn't resolve the issue. Appreciate the update.
For those interested in troubleshooting: The issue stemmed from the CPU needing replacement. Additional details that could confirm this pattern include random restarts during booting, especially while performing simple tasks like browsing or idle operation. These occurrences were linked to a "WHEA-Logger Error 18: Cache Hierarchy Error" in the Windows Event Viewer. The problem began roughly a year prior to the CPU failure, ceased for several months, and resumed around a month before the CPU stopped working.
