What to do if your motherboard or GPU is not working properly?
Hey All,
Looks like I've repeated this question many times without success. I checked the attached guide, but nothing seems to fit.
My PC has been functioning well for about three years. A few days ago it started normally and then shut down unexpectedly before I could do anything. It restarted right away, loading for around 30 seconds before going back down again. This cycle repeated several times, keeping the system on for 30 seconds to 10 minutes. During longer intervals, the CPU temperature stayed between 40-60°C (reaching close to 60 after multiple restarts).
After roughly ten such occurrences, the video output completely stopped. There’s no POST or BIOS signal, and the monitor display is inactive. The GPU fans spin but don’t power up, and the error light stays off. The case, CPU, and PSU fans all seem to be working properly. I’ve tried booting with one RAM stick at a time without any changes. The motherboard speaker is installed, but no audio comes through. I also attempted booting without the GPU, using only onboard graphics, but got no response or lights.
Unfortunately, I don’t have access to a different PSU or GPU for testing. Based on what I’ve seen and the specs, what could be the issue? I’m considering the GPU, PSU, or motherboard as possible causes, though the fans are running normally. I also know the monitor and cables work fine when connected to a laptop.
Could there be another factor at play?
Welcome to the forums, newcomer!
I don’t have access to a different PSU or GPU for testing, but based on the description and specifications you provided, could there be any possible causes? I considered the GPU, PSU, or motherboard, but since the PSU fans are running normally, I was leaning towards the motherboard or GPU.
Troubleshooting isn’t about blaming a single part; it’s about finding the real issue.
You’ll likely need to replace a component or borrow a working system from someone else to determine the exact problem.
Your motherboard has a feature called Q_Flash_Plus(white) button (located in the middle, left-hand corner); try updating the BIOS with the latest version and see if it restores your system.
Well, if the issue remains unchanged without a GPU, I'd think it's probably not the cause yet and should be left aside for now. When checking RAM and other parts by removing or moving them, always reset the CMOS between steps.
Thanks for the Q_Flash_Plus idea - I've just tested it and nothing changed, fans not working and GPU not active, no video. Since I live in a rural area, my friends nearby have parts that are probably 2-3 hours away. I'm more concerned about which components might be failing first. It seems I'll need to ask for help and bring some reliable spares when I get back to the city! Cheers
Try swapping out the CR2032 BIOS backup battery. Some motherboards won't start when this component fails.
A fresh battery will show 3.25V when measured with a multimeter. I swap batteries that fall below 2.50V.
You might want to get a replacement CPU, such as a Celeron or Pentium from this list.

You'd likely need to invest about $50 on eBay, but you could resell the CPU if it doesn't emphasize the issue.
Thank you for the advice! I attempted using a new CR2032 battery but it didn’t work. I’ll consider purchasing additional components to have backups ready for similar cases moving forward.
