Try removing the battery for 30 seconds.

Before you start pulling the motor down, just check the ignition unit has not come loose and is hitting the flywheel

reinsert d battery

i ran into the same problem today with another proform model. i shut the machine off and lifted the platform to the stow position and brought it back down, turned it on. it worked fine during a workout. i was using an ifit sd card when it got stuck. were you? just wondering.

re-flash the image and all should be fine - search the web there are companies who could do that for you at a very reasonable price

Is it possible that you have changed the settings of what buttons do what on your system? E.g. you could have changed the power button to "switch user" instead of "shut down", to check this (in XP) go to "Power Options" (in Control Panel" and then click on the "Advanced tab" at the top, then select "Shut down" from the drop down menu at the bottom of the window.

If this is already set to shut down then maybe you could do a system restore in case another setting has been changed, restore it to before the PC started doing this.

Alternatively try actually choosing "Turn off Computer" from the Log On screen (press Ctrl + L to get to this screen, or choose switch user/log off). If you are using Vista I beleive that there is a shut-down option from the Log In Page there (which again you can access by pressing Ctrl + L on the keyboard.

Hope this helps!

Clean front and back + - terminals in camera careful with fine emery paper. Also, MAKE sure batteries are not loose if they are they will not make the connection. Fine jeweler screwdriver will pick them out enough.VERY CAREFUL.I truly think this is it.regards Billy

keep start button pressed 30 seconds, the pc should turn off. If not brutally unplug the power cable. Do a scan disk on restart.
