well it depends on your set up. If you have a TV box (like from dish or cable company) make sure all cables are connected correctly and tightly. (you may want to unplug them and replug them in just to be sure. also if you have a TV box then unplug that and replug in.

now this works sometimes. use t-cut as you would for a car make sure the tv is cold and rub it in slowly going round in a circle across the scratch. DONT push hard onto the screen. clean off when it is dry. then use some lcd screen cleaner and the scratches should not be noticable now.

The first thing you should do is a proper 'powercycle' for all of your internet equipment.

To do this:

1) Unplug the power to your modem and your router, and power off your computer.
2) Wait a full minute.
3) Plug the power back in to JUST the modem.
4) Wait some more - for the modem to fully connect to your ISP, and the lights to indicate. If you're not sure, just wait about 2-3 minutes.
5) Plug the power back into the router.
6) Wait another minute or two for the router to finish connecting.
7) Then turn the computer back on.

You can bypass the computer turning on and off if you can repair your wireless connection.

If this doesn't work, there is a pinhole sized reset button on the router itself that you will need a toothpick or somesuch to press - press and hold the button for 5 seconds, and then try the steps above again. If you do this, the network id and password will be reset to the default, just like it was when you bought it.

check crystal & some heating it.clean mother board.

sounds like your windows installation took a hit, try booting from the windows cd into the repair console and do a chkdsk /F /R; a fixboot and an fixmbr command. if ths doesn't work, try the repair option. You can also try to boot from a hirens boot disk and try the tools that come with that.
