Question about Dell Dimension 5150 (DIM515MIN) PC Desktop
When i press the power button, i hear a click and only numbers 1,3,and 4 light up on the display. The pc then shuts downs by itself and then about 3 seconds after it starts up again with only the 3 numbers mentioned lighting up. The pc will not boot up. Any assistance will be greatly appreciated.
Try a different monitor. If it does the same thing then the problem is with the computer. It could be a lot of things. I would first test the memory. Take out all of the memory sticks, re-insert one at a time and power up. If it boots with any one stick of memory then the problem lies with one of the other memory sticks. Also make sure the cooling fans are all working, especially the fan on the CPU. Some computers will not boot if this fan goes bad. These are a couple of easy things to test and beyond that it could be a lot of things: Power supply, graphics card, hard drive etc. You can find ways to test these things on these pages.

you plug in the power cord is there any lights whatsoever on the laptop, where
the plug goes in or on the AC Adapter of the power cord?
When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the computer is trying to boot or may have booted, but the screen is not showing for some reason.
Beep tones and blinking lights tells the technicians what is going on with the laptop and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).
Maybe you have a Static Charge Buildup. Remove the Power Cord, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in and hit the power button to see if it boots.
your memory is bad or the memory slot is bad.
Remove the Power Cord, Open the Case and remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.
