Plugging in headphones causes problems...

[hans030390]

I believe this is similar to another thread on here where a guy's computer restarts with a static electricity shock. When I go to plug my headphones in, the computer seems to shut down as soon as the metal of the plug touches the headphone jack (front panel port). However, the computer is still powered on...it's just not doing anything. Restarting it is the only way to get it operational.

I recently bought a new power cable for the computer from Monoprice, as the one it came with wasn't long enough for the location I wanted to put it in. I wasn't having these issues until I changed the cable and moved the computer.

When I got the cable, I could barely fit it into the socket on the PSU. Because of this, the computer would turn off it I even slightly moved the cable while it was plugged in. So, I stuck a flathead screwdriver into the holes on the cable (with it unplugged, of course) in order to separate the metal contacts a bit more. This helped it fit most of the way in...enough so that it won't turn off if I slightly wiggle it.

While I'm fairly sure it's the cable that's causing this, I'm not sure if that last bit of info is of much use.

What should I do about this? Or could it be something other than the cable?

A) What happens after reverting to the old power cable?
B) What happens when you jack in to the rear output?

I never encountered this issue with the old power cable. I can't test the old one right now, as it's not long enough for the computer.

I believe one time I tried plugging a USB device into the back of my computer, and it also caused the same problems.

A) Get an extension cord, or get up and move the damn thing
B) Grab a flashlight and crawl under your desk
