I have a dell optiplex g240..it show on the monitor..windows not shut down properly, I wait the 28 seconds for it to start and the monitor cuts off, and I can't cut off tower unless I unplug...what could be wrong? I tried safe mode, and all the others...and it still cuts off
What service pack do you have installed? When did this start? Have you tried waiting for five minutes or so after the monitor cuts off? Edit: You could hold down the power button for like ten seconds to power off rather than unplug.

I ran a diag. test, and the hard drive was good..but after taking out the cd, and rebooting, the fan on the power supply was going so fast, I was afraid it would take off and fly..typical example of a bad power supply..that would prevent it from booting correctly?? Window Xp sp3 by the way...
