It's been functioning well for a while now, but suddenly it's acting up unexpectedly.
the pc is brand new, just a few months old, and it’s been running smoothly for months. today i came home and tried to turn it on, but when i switched the usb to a different slot for my mouse, it only powered up briefly before stopping. i’ve already removed the cmos battery, but i’m still not very experienced with this stuff and worry the pc might be damaged. the file i have is 77592950848__701BDD44-C3AB-4872-9EC4-0152DF15D2F5.mov.
Your screen shows nothing, or are you focusing mainly on the mouse? Clarified August 3, 2025 by 1ball
I’m sharing my genuine suggestion based on what you mentioned. Since you’re new to this and your system uses hardline water cooling, I think you likely don’t know much about troubleshooting yet. I’d advise staying cautious—don’t dig too deep unless you’re sure. Because the machine is only a few months old, it should still be covered under warranty. Reach out to the manufacturer for help. If you can provide more details, such as your motherboard model or any error messages, it would be useful. Also, check your motherboard for LED indicators labeled like "CPU, DRAM, VGA" or similar, which can guide you in diagnosing issues. Finally, observe how long the computer takes to boot—wait a moment before assuming something is wrong, and note whether fans run at full speed from the start.
Verify there are no shorts on your motherboard and confirm all standoffs are properly installed. If issues persist, consider using a different power supply—preferably a high-quality model with robust safeguards, such as effective short-circuit protection that won’t trip during startup. Note: This system wasn’t built by you; return to the source and seek assistance. Updated: August 3, 2025 by Rysters Tech
Newly confirmed yes. We built this together, but now I’m troubleshooting on my own. After checking the CPU light and RAM indicator, the GPU green light appears but the system still boots normally. I plan to test each RAM separately, then try removing the GPU to see if it starts from the integrated graphics. Using the PSU from our old build should help resolve any power issues.
During the process of diagnosing her issues, I realized my approach needs adjustment. To access more data, I had to clear and empty my system, inspect each RAM stick and GPU without a slot, and try booting from the motherboard IGPU—still no results. After replacing all components, I reinstalled the motherboard manual. While starting up, the screen shows a persistent greenish-yellow light that stays on, even though the manual says the boot device is faulty. I’m not sure what this means or how to resolve it.
Are you using another computer with an SSD? Try connecting your SSD to a different machine via M.2, SATA, or an adapter. If it works, perform an S.M.A.R.T test using manufacturer software or tools like Crystaldiskmark. Back up data immediately if the drive shows poor health and replace it. New parts usually come with warranty coverage. If it fails, contact the manufacturer. You can also experiment with different slots or cables to troubleshoot. Great effort building your system—keep pushing for better cooling!
I have an older secondary system I can access and swap an SSD in. This build uses two 2TB SSDs without a traditional hard drive, so you should be able to remove one, test it in your old setup, and then install the other. Thanks for the great tip—this is the first PC I’ve assembled since high school when I got the 1080Ti. It really shows how much I’ve learned!
