Windows 10: Broken Computer???

I have a wireless HP computer… and I made the fatal mistake of changing my time zone. I set it two years ahead just to see what would happen, and then it disconnected from all my networks. I can’t reconnect because when I click “show available networks” nothing pops up. I’ve changed back my time zone and also tried forgetting and then adding the Wi-Fi networks, but nothing is happening.

Is my graphics card broken?

UPDATE: Please see here.

I have a Sapphire HD 4830.

When I boot into XP all is initially fine and I am able to see the desktop.

However, when I click on the start bar and navigate a few steps, I receive an immediate white screen of death and a total irrecoverable lock-up.

I am confused about what this could mean and I would be grateful for any suggestions on the best course of action to test and repair the problem.

Does this sort of issue suggest that the graphics card is irretrievably broken?

Does this computer build have compatibility problems? Opinions welcomed!
