Not sure the model, but have this Dell tower system with unusual power problem.
Many times when you turn the system on, the lights all come on but the main fan and drives never come up and no video. BUT, if you open the case and just brush your hand across the inards it suddenly comes to life and continues to run perfect.
I assumed a loose power connection on the MB or something, but once that sucker is running.......no amount of pulling, pushing, twisting, rocking, or biting of any of the inner cables will make it shut down. It runs great after it begins running.
IS THIS SOME WEIRD STATIC PROBLEM? Anybody heard of craziness like this? Any ideas?
