I have a new PC, a Lenovo ideacentre, that I've had less than two months. It had been beeping twice whenever I turned it on, and I had ignored it; I d never had a computer that had a beeping-based error code before, so I figured it was just something Lenovo PCs did.
In any case, last night, I went to turn it off via the Start menu s power options and instead, it dropped me at the login screen. I figure I misclicked and try it again, from the login menu s power options, and it does the same thing; I click Shut Down, and the screen flashes off for a second or two, then comes back on at the login screen. I do it one more time, then just decide that I ll turn it off at the button and figure it out later if the problem doesn't fix itself, as they re prone to doing.
This morning, I go to turn it on, and it won't boot. Or rather, it tries to, does its two beeps, then just sits there, the screen displaying a gray box with the words, "No Signal," in it. If I press a key on the keyboard, or more or click the mouse, it acts like it's trying to boot again, beeps twice, then sits there some more.
