Device isn't showing on screen yet, but supplying power to connected devices.
Details: Motherboard model B450 Gaming X, GPU from gigabyte, RX 580 Armor OC, 8GB RAM, CPU from Ryzen 2600, power supply unit MSI RX 580, RAM modules Corsair CX650M, HDD from Kingston HyperX Fury 8GB at 2666MHz CL16 DDR4, SSD from Seagate Barracuda 2TB ST2000DM008, RAM stick from ADATA SU650 120GB. Issue: Computer failed to power on after being left unattended near a dryer in a poorly ventilated room. No signs of moisture inside the case. Attempted CMOS reset via battery and jumper, both unsuccessful. No peripherals or GPU connected beyond the Wi-Fi card. PSU fan works when plugged in; only the Wi-Fi card appears to activate. Possible causes include dead CMOS battery or internal failure. No prior problems reported. Help would be greatly appreciated. Thanks!
It’s unlikely a dead CMOS battery would block your PC from starting. Consider testing another power supply or motherboard. I didn’t fully understand your issue. What’s the connection between the dryer and the computer? Does it raise humidity significantly? Inspect all connectors.
It seems a dead CMOS battery wouldn’t prevent the PC from starting. The machine would have been badly damaged in a poorly ventilated space after the issue. I’d suggest switching to another power supply or motherboard. I didn’t fully understand your problem. How does the dryer relate to the computer? Does it raise the humidity significantly? Make sure all connectors are secure.
The dryer raised the moisture level in the space significantly, causing visible water stains on the roof and possibly damaging the CMOS chip. I think it’s best to replace the power supply unit first.
Yeah, I faced a similar issue with OPs. Swapped the battery and it didn’t turn on right away—hoped for 15 minutes, then pressed the power button and it finally started functioning normally again. Switching the battery seems simpler than replacing the PSU, but it depends on you.
I’m planning to test the battery first before the PSU since it would start up once powered on and the fan would be running. A weak CMOS battery might also lead to date and time settings becoming misaligned, causing odd hours and times. This has been happening over the past couple of days. Thanks! ^^
I began taking apart my PC once it failed to respond when the power button was pressed. Before running a PC diagnostic, I replaced the battery and after 15 minutes it began to boot. I had cleared the CMOS several times prior. It seems the issue was related to the CMOS battery; the Windows clock displayed incorrect time on a few occasions before the system froze.
