My computer crashes during anything. Booting up, connecting to the web, surfing the web, opening control panel, trying to install something...basically everything. When it locks up the only way I can turn it off is through the power supply and not from the front power button. Sometimes after I turn it off, it won't turn on for a while. If you want to see more of the problems I've been having do a quick search for my username. I'm hoping this is what is wrong and not something else. What do you think.
