Default Big Problem - Please Help

Ok, I built about 3 weeks ago.. all was going well, untill 2 days ago.. I shut down my computer every night, well.. the next morning when I went to go turn it back on.. the computer itself would turn on, but nothing would pop up on my monitor... I looked inside the case while turned on, and the reasoning was because my processor fan wasn't turning on.. which wouldn't start the computer. So now, what I have to do to start my computer. Is unplug the plug on the back.. turn off the power supply untill light goes out, then put back in plug, turn on power supply again.. and start it again untill the fan starts spinning, which usually takes 2-3 tries.. What is causing this? problem with my HSF? Or my power supply?.. and, what I am doing.. is it bad for my computer? Simply unplugging the back and turning off the power supply.. then 5 minutes later turning it back on?

Thanks for the help in advance.

Make sure all the connections are tight and secure. Try plugging your CPU fan, to another 3-pin fan header, on the motherboard.

Alright, should I do that now? Or can I wait untill later? This can't cause damage to my system can it?

You can do that now, if you want. I don't think it will damage the system, by constantly unplugging and plugging, but it's not practical.

It would probably be more helpful, if you can tell us, the specs of your system.

Do you have a spare PSU to try out and whittle down what the problem is? Basically, start replacing them one by one to see which one was/is causing the problem. But if you have no extra parts then it's hard to do that, of course. Have you also check all the wiring? a wrong placement might cause this problem. I would suggest go ing with the HSF first, if you need to replace something... al least that would be a little cheaper at the start.

Are you overclocking? What HSF do you have? I would do what Nukem suggested, if you can try out another PSU.

Yeah I wouldn't be surprised if it's a psu problem. As for the hsf, try another 3 pin header like b1gapl said. And, if you're using a 3rd party hsf, try the stock one.
