Windows 10: Resurrect an old PC that has totally died

I have an old PC Dell Inspiron 520 that I have not used for years, probably running Windows 7 I don't remember upgrading. I can't remember the admin password, but that is probably irrelevant. It won't even start. I think it is because the clock battery is totally drained and it doesn't know the time or date.How can I resurrect this PC?TIASteve

Resurrecting old laptop

My laptop crashed and I am trying to resurrect an old one to finish out the school semester. I've spent a couple of days trying to track down what I need to rebuild it. I cannot find the windows product key. It is not on a sticker on the bottom of the
machine.

It is an older machine so I know it had windows 8 installed at one point. I did a partition and it said it could not find windows, not sure if I did it correctly.

Without the product key for 8, I cannot purchase 8.1. Not sure what my next steps are since Microsoft no longer supports those old operating systems. What do you recommend?

Thanks.

 

Unlink an old android phone from my pc

I go thru the suggested steps: Start - Settings - Phone - Unlink this PC.

When I first open the "your phone" screen the old phone is listed. Not sure if the phone listed is suppose to be selectable or not, but my is not. When I select "Unlink this PC" the phone listed is removed. When I select "Add Phone" the old phone still
shows. I have removed the old phone from my Microsoft Account. I have rebooted after unlink this pc but I still cannot remove my old phone.

 

Stuck in Automatic Repair = inadvertently changed C: drive path?

@zbook- what I'm suggesting should resurrect the PC, provided what's left on the "C:" is at all viable - the clean install is just a step to that. Saves a lot of technical bits and time on our part.
