Intel motherboard suddenly stops

[wolseley]

I have got this motherboard : Intel Desktop Board D860PERL,,,,,,I just tried to change the case for it, now it does not work.

I unplug all the cables (CD and HD ,,the FAN does not spin (some time just start to spin and then stops) . I removed the cmos battery does not fix the issue.

I tried another power supply same thing still going on.

I have got another motherboard it behaved same thing with both power supplies? I do not know if I did something wrong with cablings ?

For the CPU fan to work (testing) do we need to connect the cables to a front panel jumper,,,,,I do not thing so,,,,,but I did connect them

I took the motherboard out the case (It might be shorting against the case) but that did not change the issue that I am experiencing

CPU fans generally connect to a fan header on the M/B.

Some M/Bs shut down if there is no fan.

What you describe re: fan shutdown can sometimes be a crowbar shutdown of the power supply because it is being asked to supply more power than it has available, generally from something hooked up wrong.
