I understand that we didn't solve the problem, but that we did our best until we found out that it's not really a problem with the system, so please consider marking as answered to help other users.

Hi,

You are certainly good at working with computer internals..

I'm afraid I am out of ideas.. I am thinking that the Bios itself is corrupted..

Reflashing the Bios may help, but I don't know how you would do that without being able to load an external device to do it..

A repair shop may have other methods, but that is just a guess, and it may cost more than you want to spend..

It might be worth at least checking..

There is a very remote chance that the problem is related to the Power Supply not providing enough, or correct voltages.. This again is just a guess.. Switching a power supply can be a lot of work and they are not cheap these days, but I thought I should mention the possibility..

Well, you've certainly got plenty of experience now inside the computer. Good going, even if the problem isn't solved. I don't really have much hope that replacing the coin battery would be a fix, but it should be inexpensive to try just to see. After that, I don't know what to suggest except a shop or a new computer. What you've got (like my Dell Inspiron 3542) probably won't make it to Win 11 anyway.

Good luck. Let us know the ultimate outcome.
