I booted up my laptop (Acer Aspire 3680) and it came up to the main screen and ask for my password. I input my password and it went to the login screen. I input my password again and it came up to my main background screen and started searching for my wireless network. it logged into the network and then the problem symbol next to the network symbol popped up. Then my network lost connection and and re-established. I clicked on the problem symbol and it told me I had a "fatal error" and send a report.
