Sounds like a small defect to where it's currently wired.
Hi I just got a mate of mine to do a build for me. we went to the local uni computer fair and got a load of components. It worked fine, but after a couple of days, the CPU fan would not start until after windows had opened up. It makes a loud long beeping noise until the fan starts, but after that it works fine and the fan runs. The other thing is that this problem only happens on a cold start, and after I've run the computer for a while and shutdown, if i start up again within a few hours it doesn't do it, but in the mornings especially after a cold night it will have that same problem. What is causing this, is it a faulty bearing in the cpu fan or is it a problem in the bios or something? Please explain in really really simple terms, I'm no computer hardware junkie. I'm just a lowly structural engineer.
