My (quite old) PC has startup problems that are really strange. The symptoms look as if the power supply would gradually increase power until the necessary threshold has been reached.
If managed to reproduce it and here is a "short" video:
You can hear that in the beginning the floppy disk makes "clack" "clack" sounds in a high frequency, the fans (CPU, GPU and one more is already ordered...) start with very low rpm in combination with some variation while the overall "trend" is that they turn faster and faster until at one point the harddisk starts off... Thrilling, but not very helpful. This can take up to 20 minutes!
So my question is:
Can you give a clear diagnosis from these symptoms? I would assume the power supply has been damaged internally? Before ordering a new one I would like to be as sure as possible if that is the problem.
Thank you very much in advance for helping me!
