Swany if you want to try to find out what the problem is, then turn off the Auto Restart.
Right click on My Computer. Go to Properties. Click on the Advanced tab. Then under Startup and Recovery click the Settings button. Under System Failure section uncheck Automatically restart.
Then when you run WMP and play a file that errors out it should show you what the error is. This may lock up the computer but you should be able to tell what is causing the error.
As to the internet connection you can always get a USB wireless network device that should connect you the same way the rest of your computers do. You really should at least upgrade your Windows or you may find future MTU programs won't work right.
