I didn't how to name this topic, but I'll get right to it. I turn on my PC and the fan just keeps blowing, the power button blinking, making a click noise when it does. This has been done before, a few times it kept making a long, loud, alarm-like noise, but usually, leaving it off for a while, it boots up into Windows and on the signage screen just fine. Now recently, it keeps doing the problem I've described. Any help?
