basically my power unit in my pc broke recently and i bought a new one and installed it. now when i turn it on for the first time it doesnt boot up, the fans hard drive etc all come on but the moniter says no signal, the hard drive is on but not making any busy cicking noises. then if i turn it off and on again it does the same a few times and on about the 5th time it boots up normally. i really cant figure out why this is it seems really odd so if anyne can tell me why plz do!
