This morning my laptop crashed with a blue screen while I was watching a video of JFK on Youtube. I shut down by holding the power button for 5 seconds. Upon trying to re-start, there was something wrong and the re-boot didn't happen. On the next try Wi ndows did something to repair the startup files, and the booted normally.
Nopw my problem is that although the icon tells me I have good wireless connection, and the Network and Sharing Center tells me I'm connected to the Internet, no data come through to by browser, neither to Firefox nor to MSIE. Strangely, the little desktop weather utility is indeed receiving data and works just fine, so I know there is a connection,
I have disabled the firewall, on the chance that the problem is there. No results. I also tried restoring the system to an earlier, happier time, but there was no effect.
Can somebody give me a clue how to troubleshoot this problem?
