Left the computer off the network for a month, everything worked normally then suddenly it stopped starting up at all.
Left the computer off the network for a month, everything worked normally then suddenly it stopped starting up at all.
My computer came with these parts: a Ryzen 5 3600 processor, TUF B450-Plus Gaming (the exact version hasn’t changed in about three years), 16GB of dual-channel RAM, a CX550 Corsair power supply, Gigabite 1660 Super, 16GB of 3200 TeamGroup RAM (two 8GB modules), and a 500GB Samsung 970 NVMe SSD.
What happened:
I built my system in mid-2020 with these components (excluding the 970 Pro, which was added last year). Everything functioned properly until recently.
For roughly a month I stored the machine, removed the RAM and kept it separate from the PC. After reinserting it, it failed to boot—no display, no response at all. When I finally connected it back in, fans started up but didn’t reach full speed.
Current condition:
The system will attempt to power on, but only partially. It will spin the fans (including GPU) when you try to turn it on, though it doesn’t fully activate.
Steps I tried to fix:
- Removed CMOS and reset BIOS settings
- Switched RAM slots or installed one stick at a time
- Reinstalled the graphics card in its original slot or another location
- Changed monitor, GPU ports, and cables (HDMI vs DP)
- Replaced CPU and thermal paste
- Tested different fan headers
- Checked PSU connections and cables
- Rebooted with no peripherals connected
- Switched power outlets and tested different ports
Additional notes:
Before storing the PC, it would only briefly power on intermittently. Once I shut it down and restarted a few times, it would either turn on or stay on with continuous power. Now both attempts fail.
My concern is that the system might be stuck in a temporary state that has become permanent. I’m unsure what the exact condition is or how to resolve it. Any advice would be helpful.
It might be a dead battery if you check the mainboard—it should have a coin cell, so consider swapping it out.
It seems you're unsure about the PSU. You might want to test it or check if it's covered under warranty.
Board replacement likely indicates a faulty motherboard. Sometimes it won’t power on even after pressing the power button. I’ve confirmed this by fixing broken boards myself—some refuse to turn on despite power attempts. Regarding dust, removing the board and cleaning thoroughly can help. For a permanent fix, take the board out, remove all components, detach heatsinks and CMOS battery, press the power button, then clear the CMOS for 2 minutes. Submerge in water for an hour or two, or use a dishwasher without detergent. Shake off excess moisture, let dry for a day or two, and see if it works. This method is safe, avoids messy solvents, and has saved me more than five boards so far.
Certainly! Here’s a concise explanation you can use:
This approach is supported by a well-structured theory that emphasizes breaking down challenges, reassembling solutions, and maintaining a positive mindset. The update reflects careful refinement on July 2, 2023.
it uses water and fully covers the board, it’s basically a deep clean that removes most debris. I usually look for damaged boards that fail because of dirt buildup—these are often fixable by thorough cleaning. Most issues stem from grime, which can be easily resolved. When disassembling, there’s typically noticeable dust, so boards with little dust often have hidden problems. One case stands out: an EP45 unit (still available but not popular) got stuck on C1, required a socket sprayed with IPA, and needed heatsink and battery removal. After cleaning it thoroughly, it worked fine—boots up normally. Interestingly, the heat sink under the NB wasn’t overly dusty, suggesting supercleaning helped. This usually fixes unexpected shutdowns, power button faults, or random crashes. I also repair newer boards with tiny chipset heatsinks, so the method seems effective across different designs.
