Try turning off IPv6 to make sure you only have one network adapter working. Don't enable both wired and wireless adapters at once. Open "ipconfig /all" and check what it says, like 192.168.0.1 which is probably your router's address (Gateway). This isn't the default IP for everyone; some routers use 192.168.1.1 instead. Check out these links for more info: Event Viewer and Reliability History. Getting good at using Event Viewer takes time, so don't rush. Instead, check your Reliability History first to see what's working right now. Take a picture of everything running well before anything goes wrong. Then ask a friend to log in after you restart the computer if it crashes. Go back to Reliability History and look for new error codes or warnings that happened right before or at the crash time. Take another picture and send me those results so I can see what's going on. Check the details carefully, even if they don't seem helpful at first glance.
