I woke up today to my computer not loading up. So i just manually reset my tower thinking okay maybe its my cd i left in. After letting the boot up do its thing I notice it said Hard Disk not detected. Then I got another screen and after a minute or two it was saying something failed and asking me to select what needs to be booted up, of course my HDD isn't listed. I check the cables to make sure they're not loose, and tried again. But no luck.. :\ Anyone know whats going on? And what can I do to get it up and running?
