So, the problem is as follows: The first time I start my PC each day, it works perfectly. The fans start spinning immediately, and the PC boots up. However, if I need to restart my PC for any reason, or if I shut it down and try to boot it up within an hour or a bit longer, the fans connected to the motherboard start spinning 5-8 seconds late. As a result, I believe the CPU overheats, causing the PC to turn off after about 10-15 seconds.
If I wait long enough, sometimes the PC starts even though the fans don't spin immediately (I believe this happens because it has cooled off enough to manage to boot without triggering the shutdown). I checked for loose cables but couldn't find any. I tried setting the fans to maximum speed in the BIOS, but the problem persisted.
I also removed the RAM and tried some old sticks I had. The PC didn't boot as I didn't put them in correctly and beeped, BUT the fans spun instantly altough I tried to start it within an hour after the last shutdown. After correctly reinstalling the new RAM, the PC booted again, but the same issue occurred—fans starting late and the PC shutting down after 10-15 seconds.
I also replaced the CMOS battery (which was over 5 years old) and reset my BIOS, but the problem still exists. I don't know if the fans are the root cause, but I assume they are because overheating seems to be the logical explanation, given that the PC works after being turned off for a longer period.
Additionally, I have tried unplugging the power cord to fully unload the PSU, but that did not solve the problem either.
The problem started suddenly, with the first indication being a crash at the Windows login screen. Since then, it has only shut down during boot and never while running. So once I get into Windows, im good!
I don't know what else to do and don't want to start buying new parts randomly. I appreciate any help in advance! If you have any questions, please ask. I'm happy to provide more information.
I wan't to add that I see a lot of errors in the Windows Event Viewer, just wanted to add that..
