Please help me with Windows Reinstall.

See here:

Then provide hardware IDs and your model of Inspiron e.g. Inspiron 5537:

Thanks so much for your help, my friend! 

I've read both pages and watched the videos, I'll try that tomorrow. Just 1 thing: Am I supposed to reply to you with the hardware ID and model?

Thanks

Just 1 thing: Am I supposed to reply to you with the hardware ID and model?

Only if you need help with system drivers.

Well, I have succesfully installed the correct version of Windows 8.1. It hanst asked for a product key, so thank you for that.

But still, brightness function doesnt work and neither does the Wi-Fi. It just isnt available, no toggles or anything. So I'll send you my hardware ID and model.

Model: 

Inspiron 14 (3442, Early 2014)

Hardware IDs are in the attachment file.

Thanks

I just did all that and it still didn't work...

No Wi-Fi connection option. Plus Windows is asking for activation, even though I already did install it succesfully.

My entire vacations were trying to fix this thing. And college started days ago. 

I'll guess I'll just have to buy a new notebook just because of that. Amazing.

Does the device manager still have errors, did you install all the drivers listed (any error messages during driver installation)?

I have received some error messages. I'm going to try installing 1 by 1 completely, that is, restarting the computer when it happens( after formatting and reinstalling Windows, which I just did ). Then i'm going to tell you if the same thing happens.

I did install all the drivers listed. I did receive errors once again, while installing the video driver and input driver.

And I checked the device manager, theres 3 errors: 3d video controller, network controller and some random unknown device.

And yeah idk if this info will be of any use: Windows asks me to activate my copy, even though I have gone through the entire installation process and it didnt ask me for the key then.

Isnt there like an ultimate solution for this? I really need my notebook working :(

Are you currently on Windows 8.1 or Windows 10?

The drivers I gave before were the Windows 10 64 Bit drivers, use the Windows 8.1 64 Bit drivers. Again download the following to a USB flash drive and then install in order.
