Question about Compaq Presario S5100NX (E120866) PC Desktop

Turns on, then shuts down before anything shows on monitor

The computer shuts down almost as soon as it starts up. Then it will not start up again until I unplug it and start over. Each time, it will just shut down again. I took the side panel off and watched the LEDs on the Mother board. A green light stays on near the CPU. When I turn it on, a red light flashes for an instant at the bottom of the board, near the board slots. I tried a different power supply with no change. I tried unplugging all the power cables to the drives with no change. I unplugged and reseated the memory chip and the CPU with no change. I don't have another CPU or memory chip of the correct type to try in it. Any suggestions? I have the same problem, I just bought a whole new computer, but my CPU fan and heatsink let the CPU get up to 80 degrees, so I bought a new heatsink, and when I try to start up it shuts off before afull rotation of any fan happens...

Is there more than one fan inside the computer? Did you double-check the connection from the fan to the motherboard? Sometimes a computer will shut down if it doesn't sense that the fan is turning on, to prevent the computer from overheating.

E machine model T3626 turns on display doesnt work and doesnt power off???


Sounds like either the Monitor is bad or the Video Card is bad. Try plugging another monitor on the computer and if it can't show a display then more than likely the Video Card is bad. If it shows on the monitor you just plugged in, then the original monitor is bad.

Montiors shut off


if the monitor goes into standbye when you plug it into the computer , it generally means there is NO signal coming from your video adaptor.
Plug the old monitor in , if it works, ide suspect the new monitor(s) are not working correctly.
if it doesnt work , you need to restart the computer in safe mode by repettitively tapping the f8 button as the computer starts, before it says "starting windows".
If you have a signal on your monitor in safe mode, then most likely you have a bad or corrupted video driver and it will need to be updated.
if you have no video in safe mode , you will need to remove the cover and physiclly check that all add-in card power cables and memory chips are squarly seatied in there slots. MAKE SURE YOU UNPLUG THE COMPUTER AND DISCHARGE ANY STAIC BUILDUP IN YOURSELF BY GROUNDING (TOUCHING) SOMETHING METAL BEFORE YOU TOUCH ANYTHING INSIDE THE COMPUTER.

AFTER YOU CHECK THESE THINGS AND TRECONNECT THE POWER AND TRY TO START......POST AGAIN HERE

Monitor Shows pixelated colors then flashes no input and turnsoff


Well the fact that your computer beeped tells me that there was a fault in either the motherboard or the video card. I would first replace the video card.

Computer shuts down problem


When you take the cover off and start up, are all of the fans spinning? If the CPU fan doesn't spin, the system will shut down soon after starting to prevent over heating the CPU
