Hi everyone, need some help here with my computer. When you push the start button on the front, the computer comes on then shuts off and keeps doing that until unplugged from the wall and then when plugged back in it will start. Bit of a pain to have to keep climbing under the desk to the socket and pulling the plug. Any ideas what could be causing this problem? Thanks very much....Colleen

Seems to me like you have hit a restart loop. Can I ask what OS of windows you are running, providing it is that.

There is a couple of things that you can do to fix this, one would be re-installing windows. This also resets the PSU and the CMOS when installing so that the Starting up process is no longer scrammbled. Altertivly, you can try this.

Just tap the F8 key a few times once you see the Windows logo pop up on your screen.

Once you're in Safe Mode, go to Start, Run and type in "regedit" That will launch the Registry Editor.

Next, you'll need to navigate to: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Intelppm4

Once you're there, look in the right hand side pane for an entry that says Start. Right click it and select Modify In the Value Data box, replace the 1 with a Hit OK to exit the Registry Editor and then reboot your computer.
