My computer cannot connect to any kind internet access after a power outage

Hi,

Last night there was a power outage which happened while my computer was still running. Today, when I tried to turn it back on for the first time since the outage happened, the internet connection does not work.

I normally use an ethernet cable, yet bow my computer is idefinatly stucl trying to identify it. This also happens if I try to switch to wifi, as well if I try to share my phone's network.

What have I tried?

Power cycling the modem/router

Factory reseting the modem/router

Switching which port on the router my pc is comnected to.

Restarting my computer countless times, as well as in safe mode

I've messed around with the network drivers, disabeling/reenableing them, unstalling and installing them again with no luck.

Windows diagnosis tools seems schizophrenic, telling me I should switch to an automatic IP assaignment, which is funny since it already is, and I can't find any conflicting settings.

Following Chatgpt, I found some services that are not running which probably should be, thay being DHCP Client and Network Location Awarness. My computer is not letting me start the former.

I've tried reinstalling windows, keeping files and apps but I get an error towards the end of the process.

Please, someone help me. My computer is still fairly new and expensive and I am struggeling financially anoigh as it is, I can not afford to replace it.
