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? mine shuts down 2 secs after being turned on and after will not let me turn it on for while after but then it repeats itself all over again...this all happened when i decided to clean it out because it was getting dusty on the fan...but instead i decided to try out another i had which was made for amd like the other i had and both made by avs and both looked bog standard so i tried itbut then after putting it back together nothing at all like i said previous just keeps turning off...ive tried to change it back to old but it does the same thing let me know if ya think you have solved it as im on a tight budget these days and replacing something i don't need to will only serve to piss me off....i reckon its either the switch or power supply but im not sure but could be motherboard or ram or battery who knows...maybe you do...cheers

So its a Foxconn Mb. Few things I can suggest. I do hope you installed the cpu before installing the motherboard & didn't forget to add thermal grease between the cpu & heatsink. One might say that you might have a short between the Mb and the case! Same problem two boards.... Did you connect the 4-pin ATX12V cable into the board which is loacted to the left of the cpu & up close to the edge of the Mb. Goto this link and follow the testing of the board.:

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.

Computer required restarting due to problems with mouse. Once computer was restarted gateway monitor would not work

Not enough information. Please describe any monitor activity when
you turn it on, do this while the computer is still off, unplug monitor, then
plug back in. It should start automatically, then show the gateway logo, then
go blank for several seconds, then show no input signal box, then shut down on its
own. If it fails to do this it is probably that the power printed circuit board
is failing, not delivering the proper power to the main board and/or the back
lamps. One can have this board repaired inexpensively by a qualified electronic

Takes to long for the monitor to start

This is a power supply problem in the monitor. There is an unstable component or components that are failing or you have some cold solder joints in the connections.The reason it turns on is that some components are self healing and will sometimes stabilize after warm-up periods.Cold solder joints sometime close after heating up in the circuit You should return to dealer for repair or replacement. Hope this helps you.

LCD Shuts down

The monitor screen may be OK, but the monitor electronics are not. YOu state that the comuter works fine with a different monitor. That leaves out the video card. If you reall ywant confirmation of a bad  monitor, Try it on another computer ansdI am willing to bet that it  will again shut off.  Take it to a shop for repair or replace it.

Turns on, then shuts down before anything shows on monitor

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.
