I'm not sure if this is the right forum. I'm sure a mod will move it if need be.

I recently upgraded my power supply, mobo and case to a sff system (qpack).

Specs are athlon 64 3500+ evga mAtx sli mobo. Enermax Libery 500w. 1 gig ocz 3700+.
Now it booted to windows with the case cover on, then windows immediately shut down. I assumed that the OS wasn't goibng to be able to cope with the hardware changes, so took off the case to sit my cd rom drive ontop to reinstall windows (my new cdromwhich is smaller isn't in yet). After I hooked that up every time I try to boot the system powers on for perhaps 3 seconds then shuts off again. It then proceed to turn on when bumped or occasionally if I touch it (different parts). If I unplug the cd rom and put the case cover back on, it once again boots. (I know it's not the cd cause with that unplugged and the case off it does the same thing). Does anyone have any idea of what is causing this and how to fix it?
 
Ok after much fiddling I narrowed it down to something to do with the power button as moving my finger *near* the button caused it to trigger. Now I earlier tried switching the way I had the power button cable plugged into the mobo, but maybe I failed to properly test both ways. I also removed the front bezel and fiddled with the cables going into the button, spreading them out a bit. Either the cable fiddling or reversing the way the power button cable went into the mobo seems to have fixed it. For future reference how does one tell which wire is ground and which is other? It says the orientation in those terms in the mobo manual, but never says which side of the plug is which.
 
Yep, you've got something metal laying around that is shorting out the computer. (Your compy has none/little grounding.)
