I have a Dell E510 desktop I use as a catch all computer, the other day it booted to Windows...then promptly logged out and shut down. I pressed the on/off switch and it started booting up, then in the middle of the XP splash screen, it shut down again, never getting to Windows. I pressed the switch again, and it started the fans, the lights flashed on the case, and then shut down.
This was getting maddening...If you can't even get it to boot long enough to troubleshoot, it makes it a tough fix.
I tried a method I have used before, I unplugged the system and removed all the USB, Video, network, etc connections from the system. Then I removed the cover so I could get at the insides. I pressed and held the power button, until the green light on the motherboard went out (The computer is still unplugged at this time) I then removed the CMOS battery. I then replugged the power cord in. I pressed and held the power button for 20 seconds....They system fans all started for a sec, then quit. Then after that I waited 10 seconds, before a reconnecting all the USB,Video, keyboard, mouse etc back to the system.
I then replaced the CMOS battery, and pressed the on/off switch again......
It fired right up, and went back to working as it should.
If this ever happens to you, try that before replacing the Power supply, Motherboard or other components..The Dell systems have been known to do that before.
