Strange place to ask for PC related help but I might as well try since I know we have quite a few people here who home build their pcs. My self built PC is actin very strangely and it only started happening about a week ago. When I press the power button the fans spin for a second and my lights come on for a second like the computer is going to power on then they stop. So I unplugged it, let it sit for five seconds and try again. Same thing. I repeat this step about five times then it will turn on fully. Once its up and running it operates fine, however this whole not turning on thing worries me. I think my power supply is causing the problem I just wanted some thoughts. Also I have a wireless KB and mouse, both of which are RF and have been working fine for 2 weeks, however last night after finally getting the computer to power on the mouse was being very erratic. It would not scroll on the desk, it would jump around or freeze in place. However, if it I put the mouse on my arm and scrolled over my skin then mouse tracked fine. I tried 3 different sets of batteries, then I got fed up and plugged in our Microsoft wireless optical mouse which worked without a hitch. Its a Logitech mouse, from the Logitech MX3000 wireless desktop. Any ideas?
