Sorry for the lack of technical information here, but my computer will not start due to one of vista's many mysterious buttons. While testing my new microphone, the outbound was too low. Having experienced this problem before, I decided to reboot the computer. When you initially click the "start" tab, there is an orange tab with what looks like a power symbol. I clicked the tab and now my computer will not restart. I have tried restarting it in everyway possible. The problem has occured before, which i decided was a graphics card problem, but when i attached another moniter the problem ended. I have tried everything that has seemingly worked for me in the past and am out of options. Please input some tips on ways i can restart my computer! All I can do is hit the power button, which will not even turn on the monitor.
