Hello everyone. I seem to be having a rather simple yet immensely frustrating issue. I'm building a computer, i plugged the power connector on the mobo, turned it on and bam, it worked. Great right, well today i came home from work and it would not work. So i opened the case up and took out the power connector, after inspecting both ends i put it back in, fans started and the motherboard light came on but only for a second. After fiddling with it some more i found that the only time my mobo gets any juice is when i put the connector from the power supply in just exactly the right place in the motherboard connector. If i push it all the way in, i can hear an odd whining noise from my PSU. Like a gnat in your ear. I'm not sure how long the motherboard will stay on, as my hands are not steady enough but i know the times have varied. Any opinions? I have a corsair cx500 and a biostar ta880GB+ if that helps. Thanks!
