If the computer shuts off completely like someone pulled the plug from the electrical outlet, it is probably your power supply. I would first check all the main cable connection from the power supply to motherboard. If the problem persists, swap out the power supply. Thanks.

I have an dell dimension e510 that boots to a black screen I have tried just about everything I can think of to fix it, I don't even see any way to boot to safe mode any ideas?


1) TAKE OUT YOUR LAPTOP BATTERY
• 2) REMOVE YOUR AC ADAPTOR CORD, that's the wall power, remove it.
• 3) NOW HOLD DOWN THE POWER BUTTON FOR 30 SECONDS.
That will drain any static electricity that has built up on your laptop system board and many times fixes the problem of a black screen. After the 30 seconds re-connect your laptop to the wall power and hit the power button normally and see if the laptop comes back up.
4- Replace your battery.
5-Restart

Dell Dimension 4600 will not reboot. I have to turn it off, unplug the power, push the On/off switch for a moment, let it set for 15 min then it will reboot. I have recently upgraded from 256kb ram to 1gb,...


from what you describe, they system will not shutdown. So try the following:
  1. Boot to safe mode (F8 at boot) and then see if the system will reboot from the safe mode.
  2. Boot to the Safe Mode again, Start RUN MSCONFIG, edit the startup group, (Basically uncheck all the items in the startup tab) reboot in the normal mode then see if it shutsdown. If it shutsdown normally, then start adding items back one at a time until you identify the items that were causing the items.
