Not powering up

I just got a new motherboard + CPU, had the company test it for me just to be sure. Install everything following the manual turn it on and then off again quick, forgot the memory card, compatible memory card of course. get the card in close the tower again and go to turn it on, doesn't turn on. I've checked the lines and everything looks fine, fiddled the tower connection to motherboard a little and plugged it in again, still doesn't power up. I'm rather out of things to try.

The CPU and fan came installed, there is a speaker hooked up and it did beep when it did turn on the first time. It sounded like everything was spinning, only had it on for a couple seconds that first time. There is an onboard video card so did not install a seperate card. Oh and all pins are connected that can be, both power connectors, the tower fan, all buttons and lights, hard drive, DVD drive and floppy are connected. Problem comes from the button for power not turning the computer on again, well symptom of the problem anyway.

Did the CPU and cooling fan come pre-installed or did you have to install it? Did you forget the separate 4 pin power connector from the power supply to the motherboard? Is the speaker hooked up and are there any beeps? Do all the fans spin up? Do you have a video card that requires additional power connection and forgot to connect it?

You must to do the test coming with the computer laptop and for hardware and software. Test it or download it from the company supplier and fix it.
You must sure, that you put everything from wiring like you have before to replace the new ones. Otherwise you must have problem. See if the motherboard is compatible for the o.s and Intel CPU., memory,
God bless you

Hi i have a P4M800P7MA-ERS2H foxconn M/B that powers up but nothingelse -doesnt boot how can i tell if its a cpu or motherboard fault ty warren

Normally the only way to be sure is to use a CPU that you know works in another computer and test it in the motherboard that is not working. Also make sure that everything is connected to the motherboard properly and you can try disconnecting everything except CPU, RAM, video, and power to see if the computer boots like that.

I just finished building a PC using motherboard Biostar N68S, but it won't power up. When I push the power button, it only works for 1 second. Everything is connected. What seems to be the problem?

Try to verify these :
1- Check that all perepherals are connected correctly (HDD, Drives...)
2- Check taht the motherboard support the CPU you are using.
2- Check that the RAM is correctly inserted (use an other connection slot)
3- Check that the CPU is correctly inseted and that the FAN is correctly placed
4- Check all USB port, may be there is a short circuit.
5- Check your AC Power.

Good Luck.

I installed everything the CPU, RAM, and everything else. Connected all switches at the right places and the BIOS is on normal operation. I turn on the computer and its a blank screen nothing shows up....

ok, looking at the specifications All I can recommend is the following. double check the Video card to make sure it is properly seated and that it does not exceed the capabilities of the motherboard. 2 Disconnect everything from the motherboard except the CPU and case wiring/power supply and turn the computer on. If the system completes the post test, you will hear at least 1 beep and should hear several for the video card not being connected, then start installing components 1 at a time till you find the one causing the problem. Start with the Video card and then the ram as these are most likely where your problem is unless you have a faulty power supply which will be the problem if you don't get a completed post with nothing else connected.

I have a foxconn p4m800p7ma motherboard everything is connected but it will only blink the lights twice when i hit the ON switch and the cpu fan spins for a second then stops.is this a dead motherboard?or...

Hi,

There could be many things that could stop the board from turning on, Determining what is wrong is like detective work. What I do, is take everything off the board to start. Then add the minimum to start a board to see if it will start. That's one drive (cd or otherwise) the CPU, and one bank of memory. (that's not a required eliminate, but it helps avoid beep codes) Also, make sure you have your pin's set on the board absolutely correct, or that could be your problem to begin with. Also, if your going to load a ide drive, make sure you set your pin setting correctly on it. Now, you should get the power supply on, and the cpu. If those don't power up, it's then either one of the five elements. The CPU, Power supply, Ram, Drive, or the motherboard. The next step is to replace each one of the first four with another to see if you get any change. Also, on the drive, try a different cable to make sure it's not that, If no change, then I usually get another board that I can test the first four, and make sure that they work. If after that and you have tested all of the components and they all work, then it's save to say you have a Dead Board
.
Good Luck and don't forget to leave a rating.
Thanks
Mark

MSI x48c mobo keeps powering on and off. Won't post. No video signal. Video card and power supply and memory are all new and all work in other computers.

your motherboard is bad. Try the following before RMA'ng it.

1. Remove all the cards and memory.
2. Recheck your power supply connections
3. Remove, clean the thermal paste and reapply new
thermal paste (follow the manufacturer's directions)
4. Reseat the CPU.
5. Install one stick of ram
6. If the motherboard has an onboard video connect your monitor to it.
7. Try powering it up.

If that works, add the rest of the memory a stick at a time. If the system continues to power up, then install the Video card, and test again. Finally if everything is functional, chalk up the previous problems to bad karma. If the system fails to power up, and stay powered up after adding a component, then that is the faulty part.
