I have a fairly new (3 weeks old) HAF X chassis with Crosshair IV wAMD 1090T BE, Corsair 850W PS and the other usual suspects, OPtical, WD 600GB Raptor, etc.. I have recently been using the front panel USB 2 port and for some reason, as I attempt to plug in a memory stick, as soon as it comes into contact with the metal outer shield of the USB port, I lose video, the sound system thumps and it just sits there. Sometimes I will get a restart beep and it reboots, sometimes it just sits there until I hold down the power button to restart. It never loses power which leads be to believe that I am introducing enough voltage to provide an arc to a shorted wire which is then causing the MB to flip out. Kind of a whacky hunch, but that is what it seems like.
After inserting the stick into a laptop and using the "safely remove" feature, if I move to the front panel of the HAF straight way, it will occur. If I ground out the stick, meaning I touch it to something made of metal that allows it to discharge, it does not happen. I've tried two completely different memory sticks, same thing.
So far, I have not been able to replicate just using my finger, so I suspect the mem stick is holding a bit more of a charge, but not sure. This is a very aggrevating problem. I have seen posts on other firums where it is also happening to folks when plugging in the HD audio headphones, but I just did that with a pair of powered dr. dre's and no problems.
Any help would be greatly appreciated. I did send CoolerMaster an E-mail. If they respond with "give us your address so that we can ship you an new front I/O panel", then I will pretty much know it is the HAF X front panel that is defective.
