"""Pop open the case, and remove and reinstall all the RAM. Do the same for the CPU. Give everything else a good push/gentle wiggle. If you have any add-on cards, try to remove & reseat/install them. This often help with the power on/no post situation.""" I agree with bob. I would unplug the drives as well. I would test the power supply pins with a multi meter to make sure all voltage is correct at eatch pin. Then just have the CPU and RAM plugged in. Then successfully plug in one component at a time. Listening for the post beep each time. ,Ron -------------- next part -------------- An HTML attachment was scrubbed...
