Have you noticed your new PC repeatedly restarting in a loop?
Have you noticed your new PC repeatedly restarting in a loop?
Hello,
My recently assembled PC experienced a sudden shutdown and is now stuck in an endless boot loop. The logo appears briefly, then the screen flashes and returns to the logo repeatedly. Attempts to access BIOS or Q-Flash were unsuccessful, as it didn’t guide me to the correct settings or display. Q-Flash Plus also failed; the PC powers on, lights up briefly, then shuts off. I also tried removing the CMOS battery for a short time. Additionally, the motherboard’s light cycles through red and changes between CPU, DRAM, VGA, and BOOT.
Build Specs
Motherboard: Aorus B850 Elite WiFi7 Ice
CPU: AMD 7500f
GPU: Galax RTX 5070 Ti
PSU: Leadex III PRO ATX 3.1 1000W
RAM: Adata XPG Lancer Blade
Any assistance would be greatly appreciated. Thank you.
Welcome to the forums, newcomer!
I also attempted to remove the CMOS battery for a while.
Best practice is to clear the CMOS by disconnecting from the power source and the display. Then take out the battery, hold the power button on your chassis for 30 seconds to discharge any remaining power, and reinsert it after about half an hour.
Also, observe that the motherboard light flashes red and cycles through CPU → DRAM → VGA → BOOT light.
If you detach the discrete GPU from the setup, does this influence the Q-LED sequence?
Test with a single stick of RAM.
I attempted the CMOS approach but it failed. Using a RAM stick slot also didn’t resolve the issue. After removing the discrete GPU, the red light cycles through DRAM, VGA, and CPU. It lingers at DRAM for a long time, briefly at VGA, and then very briefly at the CPU.
Q-Flash Plus also doesn't appear to function; the computer will simply power on and illuminate before shutting down.

Even with a different board, the same steps apply.
Examine the socket for any bent or damaged pins. How is the processor being cooled?
I can access BIOS now, but my keyboard isn’t working. I’m having trouble updating BIOS via Q flash or plus. Q flash plus also has the same problem—it flickers and shuts down. Q Flash just displays “can’t read the file” even though I think I got the correct file. I saved a file ending in .f7d on my USB drive. When I choose window as boot or try to reinstall using a USB live installation, it keeps looping. My CPU is cooled with a thermal AIO cooler; it ran for about a minute and completed a few cycles.
If you manage to get past the BIOS splash screen and the system restarts while attempting to load Windows, it strongly suggests a drive or Windows-related issue. Typically, a Windows problem will direct you to the recovery mode after three unsuccessful boot attempts. If the computer doesn't reach recovery, it could mean the motherboard isn't able to access the recovery partition at all.
Do you have a Windows recovery USB drive? If you can boot from that, it would indicate the hardware is functional and points to the drive as the problem.
By the way, if a computer operates normally but suddenly crashes and fails to boot, updating the BIOS won't resolve the issue. Many recommend a BIOS update for general fixes, but it only works in specific scenarios such as hardware replacement.
