2 pin or more??, Computer won't start

[Davve95]

Hi!


I bought a wanged motherboard today very cheap to have fun with... But when I tryd to start it it didn't happned anything!.. I've tryd with this:
Take out on ram, and then the other with out sucsses.. And also changed power cable.. And also checkt if there was a cpu (there was)...

And nothing workt.. But I'm abit unsure:
Where the power button cable pin thing should be.. I tryd with a 2 pinned but I'm not sure
if it should be it..

Thanks alot for replys and helps!!!.

Follow this procedure:

Having problems with a new build? Try this.

Systematically short 2 adjacent pins and see if one combination will respond.

or google the model of the board and get the manual...

Alredy did but didn't helpt :/..

[doubledragon5]

Might have a dead board...

[Davve95]

Maybe..

Any more help??..

Try briefly shorting the two pins marked in yellow. Notice the label "PWRBTN" (PoWeR BuTtoN) beneath them, just above the label "RESET".

You didn't see that?



It wouldn't hurt to have a motherboard speaker connected, if the motherboard doesn't have one, to hear any diagnostic beeps.

If shorting those pins makes the CPU fan spin but nothing appears on the monitor, briefly short the two reset pins.

BTW, take some precautions against static electricity, i.e. don't place the motherboard on top of a plastic table or carpeting but instead use a piece of anti-static foam or bubble wrap or a pink anti-static bag. The silvery bag for a new motherboard is safe if you turn it inside-out (typically, only one side of the bag is anti-static). If you don't have any of that material, use newspaper, a brown paper bag, or brown or grey cardboard, but always avoid any of these that are shiney.

I don't know if the VIA VT8237R Plus chip is compatible with SATA drives configured for maximum speeds of 3.0 gigabits per second or more. VIA came out with several buggy versions of the VT8237 chips, and I think they didn't fix this problem until the VT8237s. IOW to use a SATA drive with one of the defective chips, you'll have to limit its maximum speed to 1.5 Gb/sec, either through a jumper (WD, Seagate, really old Samsungs) or utility program (Hitachi, Samsungs made within the past ~4 years).

Okay thanks alot!! .. If it happen that with no picture on screen should I do that on the pins?....,Works with screwdriver??.. Yeah I saw the text but didn't saw where to place the power button..

Hope I understood alll right...

Edit: It works now but I don't get any picture.
..But the fan on graphic card works...

[Davve95]

I'm very sorry for bump but I need help..

Should I "touch" the reset pins with screw driver? Or something if I don't get any picture??..

Hope I understood right what he meant..

[kilgoretrout]

See the two pins circled in yellow. Take a screw driver and touch it to both pins simultaneously so they are electrically connected.

[glc]

Touch the PWRBTN pins with a screwdriver, and when the CPU fan starts running, remove the screwdriver.

What is the brand and model of this motherboard? Does it have onboard video, or are you using a video card? Are you using only one stick of ram, as indicated in the procedure I linked? Is the main power connector connected, and does it also have a 4 pin CPU power connector? That also has to be connected.

That wasn't what I askt.. I talkt about this:

"If shorting those pins makes the CPU fan spin
but nothing appears on the monitor, briefly
short the two reset pins."

And I wonder if I should touch those pins...
Because I have that problem.


Anyway thanks alot!.... My motherboard: AsRock K8upgrade-vm800..

Edit: It's running now expect picture..
Like said in earlier post..

Idk if it's in-built or not.. But had a normal graphic card.

Edit2: Yes 4 pin connected.. 2 ram sticks.

[glc]

Use ONE ram stick, and do NOT worry about the reset pins.

That board has onboard video - remove the video card and use the onboard video.

You ARE doing this with the motherboard NOT mounted in a case, correct?

Okay thanks! I will use onboard instead.. Yes I don't have it in case now..
Because I would just see if I could start it up and then I will get a case for it...
But why don't you recommand the video/grapich card?? Just wounder ..
Has to do with a setting or something?...

Thanks!.

To rule out the video card as being the problem.

Edit: Still didn't got picture And I tryd with 1 ram memory..

[Davve95]

Need help again.

Sorry for bump...

[doubledragon5]

It is sounding more like you have a bad cup or motherboard at this point... You get no picture using the on board right? If so now try the video card. Not sure if it will work as you can't get into bios to select it. Unless it defaults to the card once it is installed..

Okay thanks.. Some one said something about reset pins maybe try that?.. More ideas??..

[glc]

Remove the CMOS battery for 30 minutes and try again with the onboard video. If it still doesn't work, let it run for 5 minutes and feel the CPU heatsink - is it hot or cold?

Please stop bumping and sending private messages - your questions will be answered in time.

Thansk! Will try this.

[Davve95]

Sorry but there ain't a edit button :S So yeah I have to create new post..

Anway: Does it do someting if I have it out more then 30 minutes??..

[doubledragon5]

It basically clears anything set in the bios, and sets it back to they way it was when it was frist manufactured.. Did you try and replace they battery...

Wasn't what I woundred.. But thanks alot anyway.. I have 1 question should the + be up or down??..
Thanks..

Edit: I will try to take out the battery tomorrow..

Flat side up.

Generally if you try turning on the motherboard but you see nothing on the screen, try momentarily shorting the two reset pins (just below the two PWRBTN pins) because that sometimes makes the BIOS switch to different settings. You may have to try this more than once. Some older BIOSes also switch to a safe mode if you hold down either the INSert or DELete key while turning on the power by momentarily shorting the PWRBTN pins.

Do you have a speaker connected to that set of 4 pins to the left of the power and reset pins? Because a speaker can sometimes provide useful diagnostic information when nothing else does. Most likely, the 2 speaker wires go to the pins at the far left and far right of that set of 4 pins, and 1/2" diameter piezo speakers may require also the correct polarity (reverse the wires if it doesn't work one way).

When you remove the CMOS battery, be sure the AC power is disconnected or the CMOS won't get reset. Short the CMOS reset pins for a minute, too.

I was wondering why this motherboard had "upgrade" in its name and what seemed to be 2 AGP slots, and it turns out that one of those slots is for a special card to allow a Socket 939 CPU to be used in place of the Socket 754 CPU on the motherboard. There are also 129 jumper pins that have to be set correctly to match the CPU socket that will be used:

How are they set on your motherboard?

Thanks alot! . I will try shorting the reset pins, where can I find the reset for cmos battery??.. Yes I also woundred why it had upgrade name in it now I know thanks . I don't know how the jumpers are placed I can take a photo?.. But I could try the reset things first??..
I'm sorry for slow reply..

look in the manual of the link provided

[Davve95]

Can I short it with a jumper?? Thanks alot!... Or can I do it with screwdriver?...
I mean that under PWRBTN pins and how long should I wait??


Ops sorry for bumb... But forgot my topic before and some day when I tryd to post it didn't workt..

Better to bumb then new topic??.....

[glc]

Use a screwdriver, and you only have to touch the 2 pins momentarily. Do not hold, and do not use a jumper.
