Motherboard wont boot

March 11, 2009 at 05:29:09
Specs: Windows XP
I GOT A GIGABYTE ga-g31m-s2l motherboard , 2gb corsair ram power colour hd 3650 graphics card ,intel pentium 4 ht 3.8mhz processor and it wont start unless i take the battery out for about an hour when it does boot everything works great i installed windows xp along with all the drivers and updates after i restart i have to take the battery out every time all the fans move and cd rom works cause i used it to install my operating system i have installed my graphics drivers chipset drivers audio drivers all from my usb mass storage device ... what i dont understand is that my computer runs great until i restart it then i have to take the battery out leave it for an hour then the motherboard boots up the monitor comes on and windows starts to boot of my hard drive ....

how can i get my motherboard to start without leaving the battery out for an hour ??? when i have updated windows i intend to leave my computer in hibernate so it does not have to boot up from the motherboard that could be a shot term solution but i need it to boot every ti8me i restart please help

Are you unplugging the power cord before you take the battery out? does the BIOS reset when you do this? Do you enter the BIOS & correct the settings before booting into Windows? You certainly don't need to take the battery out for an hour...it only takes a second. But you should be using the clearCMOS jumper, that's what it's for.

Tell us about your power supply. Make/model, wattage & amperage specs.

yes i take the power cord out then take the battery out . my power supply is the power supply i got with the case its a 450w winpower power supply atx 450

i am on my computer now and have installed several programs of which one is company of heroes which runs great my whole computer runs great apart from when i turn it off

when i do put the battery in and it does start up i go straight to windows
should i go to the bios before windows ?? if so what needs to be done

its obvious that all my components work cause when it does start i can install programs surf the net and play games eg company of heroes
when i restart after puttin in the battery a screen comes up with cmos check sum error

then underneath some booting options with how many attempts next to it i choose default then my computer reboots i hear one beep and windows starts

when i first had the problem i took the power cable out and put the cmos reset jumper on left it for a minute and took jumper off and started it up

my computer will only boot after i have left the battery out for aprox 45 min i tried 15 minutes and it wouldnt work i had to leave it for 45 minutes

Try a new battery. It's probably weak. Taking it out for a while lets it rebuild it's charge a little.

Yep I agree with aegis. A weak battery could also cause the CMOS chip to act flaky, causing the system to not be able to read from it properly when your computer starts.

That motherboard has on-board graphics. Perhaps there's a problem between that adapter and the video card you've added. Try using only the on-board graphics and see if you still have the problem. Or pull the card after you shutdown and immediately restart using the on-board adapter.

If the problem goes away when not using the card, check the motherboard manual and see if you need to do anything special when adding a card. It's probably a good idea to check any installation instructions that came with the card too.

Age of system? I'd check Power supply, and power button light Iif you have one, to see if its amber or green etc. Checking a PS can be hard to do unless you have the proper tester and PS is under load though.

Also look for weak, bulged capacitors on the motherboard:

Just another stupid saying...

I doubt anything is wrong with the video card. I was thinking that removing the battery forces cmos to revert to its default status which, for some unknown reason, then allows the card to work. That points to some conflict between the two adapters. That's why I think it's important to know how it works with only the on-board adapter.

Also, are you sure that removing the battery is necessary? Maybe just unplugging the power cord for an hour will work

thats a good point about leavin it for an hour just plugged in ill try it and ill try with graphics card out

the thing is the graphics card works when i do start windows and i check it in device manager and it says its ok there

ill try leavin it for an hour pluged in and see what happens

i hust want it to start rather than takin out battery everytime its so annoyin
it is cheaper to build ur own pc by god its mind boglin when somet goes wrong

could i need a new mother board or because it does start after battery has been out does that say all my components work???

Does it boot if you turn the system on without the battery? It should, but you'd have to set the time everytime the system is unplugged.

So you're saying it'll startup when leaving the cmos battery in but you still need to leave it sit for 34 minutes? If so, it doesn't sound like a cmos problem. But I still wonder how it will act when using just the on-board video.

Might be a PSU issue. Are you using a 24-pin PSU-to-motherboard connection? It looks like there's a 12-volt ATX connector just behind the mouse and keyboard although I don't know if that's needed if you use a 24-pin power connection.

Also, check in cmos/bios setup for the 'start on' events. It doesn't seem like that would be a factor but it wouldn't hurt to toggle some of those settings and see it it helps.

right i got it down to leaving my pc offf for 8 minutes then starting up everythin boots and starts as normal when i restart it won start until i leave it for 8 minutes i tried with the 12v atx connector and it came on but didnt start i did notice with that 4 pin 12z atx connector out i could not turn the power off by pressing and holding the power button

my computer does strart and works but immidiatly after rebooting i have to leave it fo 8 minutes now befor it will go to post and boot up

That's better I guess. But it'd still be interesting to know how it works when using the on-board graphics adapter. Another thing--try disconnecting the monitor from the graphics card after you shut it down. Sometimes power can feed back from the monitor to the card and then the motherboard. Then reconnect it and see if it starts up.

If nothing changes you might try swapping out the power supply. I wouldn't necessarily buy a new one yet Just temporarily swap it with another to see if that makes any difference.

I don't really have a recommendation--others might though. It's probably not a good idea to spend money on a new one until you're sure that's the problem.

Pull out the video card and just try the on-board.

The fact that everything seems to power up doesn't necessarily absolve the PSU. The fans only need 12V and the drives and LEDs need 12V and/or 5V. The PSU has to provide other voltages to the motherboard.

If it's not the video card it could be just about anything--PSU, motherboard, CPU.

You might want to try another PSU then, but be careful of buying new stuff in the hope that you'll randomly find the problem.

Check that the RAM sticks are firmly installed as well as the cpu heatsink. Temporarily remove any cards you don't need and disconnect the drives and see if it at least shows a posting screen.

I'd go ahead and try another PSU. Again if you can do that without actually buying one, say by temporarily using the one in the computer you're on now (assuming you can remove it safely), you'll probably be better off since at this point we're really just guessing at what the problem may be.

It's got to be the PSU, motherboard or cpu or a combination of those--such as if a bad PSU damaged the motherboard. Trying a known good PSU is probably the first thing to try.

the other psu has onlu got 20 pins but so is no good i did notice on my psu that its 24 pin and one of the pins is missing of which there is no wire even going into one of the 24 slots ???????????

That's OK. There is a certain voltage required for ISA slots so that is often omitted in PSUs designed for newer motherboards without ISA slots.

A 20-pin will work in a 24-pin slot. The molex connections are shaped so it'll only fit in the correct way. I think when using a 20-pin in a 24-pin slot you need to connect the 4-pin ATX also--not in the remaining empty 4-pins on the power connection but in its regular place.

I am coming here late so bear with me. First off, the CMOS battery has only one function. To hold settings when all power is removed from the computer. If you leave the computer plugged in and don't use a power strip or similar device to shut off power then the battery strength is of no importance. You do need to reset values in the BIOS though. If you think there is something going on with the BIOS settings then do this.

Check all the BIOS settings including date and time. Boot to Windows and use the computer. When you want to quit reboot to the BIOS and see if all the date and time are still correct.

Now, to see if there is a fault in the PSU (power supply) that is causing the failure to boot issue do the following. Pull the plug on the computer and then depress the start button a few times. Plug in the computer and try to boot. If it boots OK you need to replace the PSU.

You can try the 20 pin PSU to test with. It may be OK to test with if the total wattage is OK. No harm can come from doing that. Your other PSU may actually be a 24 pin connector anyway. Most 24 pin connectors are actually a 20 pin + 4 pin, which can be disconnected from the rest of the connector. That 4 pin section may be loose or may be plugged into the motherboard.

Your CPU MAY be overheating. Boot into the BIOS (setup) screens and look for PC Health. The system and CPU temps should show there. Leave that screen open for a while to see where the temps climb to.

Other issues include CPU cooling fan, the secondary power connections to the motherboard and possibly the graphics card. Cold solder joint somewhere on the motherboard (hard to troubleshoot), dirty or poor connections between the motherboard and any of the components like the graphics card, RAM. Try snapping the RAM stick in and out 4 or 5 times each. Watch the CPU fan when you first try to start up.

Do you get anything at all when having the start up issue? How about beeps?

That's probably a memory error:

Did you add or change the memory recently? Try removing the sticks, cleaning the slots with some compressed air and reinstalling them. If that doesn't work the memory may need to be replaced.
