Re: This Dell won't shutdown!
I'd normally say call dell, but considering their support is useless and hard as heck to understand, you're best off not doing that. I'd say try opening up the PC and see if anything looks out of order, also try making sure the power on after power failure setting is in tact, or even try modifying the setting.
Desktop: Dell Dimension E510, 2.5GB RAM, Intel P4 3.0GHZ, 250GB HDD, Windows Vista Premium. Might not be the best, but the old girl is still running good.
