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

Re: Turns on, then shuts down before anything shows on...

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.:

The blue screen is just there it wont go to the menu

If you have done any updates or changed anythng recently,ie;change of cables, resoltion etc. Try a shut down using power button on tower and unplug. Plug back in and start in safe mode. Click "start" find "control panel", click on that to open. Find "device Manager", right click on that and open. Click on the box with + next to dispaly adaptors. You will get a drop down of you devices. Right click on the one you use and you should see "disable", if you see "enable" click on that. Click on the box with+ next to monitor. You should see a drop down ith your monitors.Right click on the one you want and, again you should see "disable" if you see "enable" click n that and exit. If either of those two things showed enable when you checked them and you enabled them you probably fixed your problem. Now restart your system normally. If it doesn't come back, shut down at front of computer and restart in "safe mode" again wait for widow to come up about system restore, now this is only if you have made recent changes o updates, Click on what is system restore and another window will come up. Read down until you see "start system restore" and click on it. This will take a couple of minutes. A window will come up and click on start restore. Your computer will perform restore and restart on it's own. After it restarts, give it a couple of minutes tillyou see a window with "system restore complete".

Just now i shut down my computer normally, an hour later when i tried switching it on again i cannot, the monitor dosent show any image, it even not shows the BIOS, the fan tuns just for a while and then...

It sounds like a hardware problem. Check the obvious like the power cables and plug it into a different wall socket to make sure that isn't the problem.

Does the computer beep when it starts up. The pattern of these 'POST' beeps can help you determine the problem. However if the computer doesn't beep, doesn't activate the BIOS and the hard drive doesn't spin up (with the HD light flickering) then you either have a fried motherboard or processor. Not an easy or cheap thing to fix.

Does it work at all now? If so I would consider get something like a laptop cooling system, since this is not your normal laptop some research is in order to get something that will work the best. I think I would definately give Dell a call and see if they have any solutions. Hope this helps.

My pc get restarting

Mostly this problem exists only when your computer is affected my virus. If the computer turns on and if you are able to get into the desktop screen and then if its shuts down, then its a virus. Try formatting your pc and install a fresh copy of a OS.

Or if the PC shuts down soon after you start the computer, its the hardware problem.Open the CPU case, remover the RAM and insert it again. try to clean the dust,

No screen image

You gonna need an spare monitor, video card and a memory card. But first have the RAM card and the video card(if plug in) be clean or reseat. Use clean soft eraser to clean its edge connector, both side. And check your video card for dirt or stock fan if it have. Do this cleaning when unit is off and unplugged to wall socket even UPS. Also reseat the monitor cable. Then try to power it up again.

Next step;

And since it beeps it seems one component is failing or loosing its contact with the board. Then use the spare ram, then the spare card, if still not viewing any try to swap the monitor.

Or if you have no spare if cleaning only doesn't help, its practical to bring it to the expert.

Monitor Shows pixelated colors then flashes no input and turnsoff

If it is a desktop, try another monitor and see if you're gonna get the same problem. If its a laptop, connect an external monitor to it. If the other monitor shows the same thing, it means to say that there's just something wrong with your video card. If that's the case, you might as well uninstall and reinstall the video driver. If in the other case, the other monitor's fine then definitely its your monitor. if there's a reset button or a factory reset button available on your monitor then reset it. If the same thing happens, get it replaced.

Newly built computer starts up without using switch

No signal means, monitor has not been connected. (for crt s) and, on startup (for lcd s) . Easiest solution should be, PLEASE REMOVE AND PLACE THE RAM TIGHTLY AGAIN. i hope, it will solve the problem, if you have recently traveled with your cpu.

Computer shuts down but does not turn off

Mchem, you actually have 2 separate issues going on there.
  • Open control panel > open the system control panel
  • in the system properties, click on the advanced tab
  • in the startup and recovery section, click the settings button
  • In the startup and recovery dialog box, under system failure, remove the check from the automatically restart option
  • click ok
  • click ok

  • Open control panel > open power options
  • in the power options properties, select the advanced tab,
  • in the power buttons section,
  • When I press the power button on my computer: click on the drop down menu and select the shut down option
  • click ok
Sebastien123, you only need to run the first part of this solution.
