Motherboard not interested in video output

Specs: Windows 7, unknowm/4gig
So I recently built a computer for a friend from all brand new parts. so as far as i know, everything is working. but for the life of me, i cant get this stupid box to give me a video output.

when it was first setup, i also had a video card and a wifi card built in. i tried using both the video output on the motherboard and the video output on the card, and no dice. so then, to eliminate any problems that may be caused by those pieces, i removed them, so it is just the motherboard, cpu, 2 gigs ram and a harddrive. (well and the power supply of course!)

but still!!! no dice!!! i am very confused!
and yes, i tested the monitor i was using on a different computer and it works fine.

If you didn't benchtest the board before installing it in the case, you're just spinning your wheels.

Have you ever had video ?

Assuming you have a case speaker or other sound device hooked up to pins on the mboard so you can hear mboard beeps, are you hearing the normal one beep from the mboard while booting ?
If no, are you hearing no beeps or a pattern of beeps, short or long, beeps then nothing, or a continuous beep or pattern of beeps ?

A video adapter that is built into the mboard IS NOT A CARD !

If nothing else is wrong, you should get video from the onboard video, unless you have a mboard that supports Hybrid CrossfireX video or Hybrid SLI video and you been messing with the bios settings. If you DO have a model that supports either of those, if you HAVE been messing with the bios settings, remove the mboard battery then install it again - then you should have onboard video.

If you have a mboard that supports Hybrid CrossfireX video or Hybrid SLI video, it supports both the onboard video and the video on a card in a PCI-E X 16 slot being enabled at the same time by default, but ONLY if the card in the slot has one of a few specific video chipsets. Hybrid CrossfireX requires that the video chipset on the card has one of specific ATI / AMD video chipsets on it; Hybrid SLI requires that the video chipset on the card has one of certain NVidia video chipsets on it.
If the video chipset on the card is a different brand than the main chipset, or if the video chipset on the card is the same brand as the main chipset but the video chipset is not one that works with Hybrid video, the onboard video will be enabled and you will get no video from the card in the PCI-E slot by default - in that case you must change at least one video setting in the bios, or sometimes two.
Some Intel main chipsets have a similar feature called Hybrid Multimonitor support.

We need
- the model of the video card
- the Version of your G31d-m7 mboard model - e.g. 6.x, 7.x, or 8.x
- the brand and part numbers of the ram you're using
- the brand and model, or at least the wattage (output) capacity, of your power supply
- the part number of the cpu you are using.

I was lazy at first and put the whole thing together. after your post i tried what your link suggested. but a bench test yielded no further results

and no, i have never seen video of any sort from the computer ever. and there has been no sound whatsoever from it either, not a single beep..

parts are as such

1) hec HP585D RETAIL 585W Power Supply
2) Intel Pentium Dual-Core E6500 Wolfdale 2.93GHz 2MB L2 Cache LGA 775 65W Dual-Core Processor BX80571E6500
3) Patriot 2GB 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Desktop Memory
4) ZOTAC GeForce 7200GS ZT-72SEG7N-HSL Video Card


I am not at my place right now, and do not have a way of telling the version of the motherboard right now, but when i get back i will update with the motherboard model

"....i have never seen video of any sort..... "

When you attempt to boot the computer, are any
- leds lighting up ?
- hard drives spinning ?
- fans spinning ?

To rule out a damaged video card, remove it and connect the monitor to the onboard video port (when the live AC power has been disconnected from the case) . When you manage to get video from that, then try installing the card (when the live AC power has been disconnected from the case) and connect the monitor to that.
(Most bioses automatically disable the onboard video when a card is installed in a PCI-E X 16 slot, unless the main chipset supports Hybrid video.)

Did you consult the mboard manual and make sure you connected everything properly ?

You MUST connect the 3 or 4 pin hole CPU fan wiring connector to the proper 3 or 4 pin CPU fan header, otherwise the mboard's bios will shut off the mboard within a few seconds after booting when no rpm is detected from that header.

"...there has been no sound whatsoever from it either, not a single beep."

Did you connect a case speaker or other sound device to the pins for that on the mboard so that you can hear mboard beeps ?

Did you have the power supply UNPLUGGED, or have the live AC power to it DISCONNECTED to it otherwise, at ALL times when you were fiddling with connections to, and plugging in components on, the mboard, AND when you plugged in the power connector to drives ?

Did you have the video card fastened down and all the way down in it's slot BEFORE you tried to boot the computer ?

Are you SURE the ram is installed in the proper direction in the ram slots ?

(If any module was installed backwards and you then booted the computer, the ram module that was backwards and the ram slot it was installed in are both fried instantly - you would probably have noticed a strong smell like the smell of burning plastic. DOH ! is not covered by the mboard's warranty. )


1) hec HP585D RETAIL 585W Power Supply"

You could have chosen a lot better than that. Going by the price it sells for, it's on the borderline between el-cheapo and just okay for a 585 watt PS.
It's foolish to cheap out on the power supply - you're a lot more likely to have problems with an el-cheapo PS.

Don't buy an el-cheapo PS.

"2) Intel Pentium Dual-Core E6500 Wolfdale 2.93GHz 2MB L2 Cache LGA 775 65W Dual-Core Processor BX80571E6500"

That may be the cause of your problem. It's not listed for any version of your mboard.

BX80571E6500

Not listed for version 6.x
http://www.cpu-upgrade.com/mb-Biost...

Not listed for version 7.x
http://www.cpu-upgrade.com/mb-Biost...

Not listed for version 7.x, 8.x
http://www.cpu-upgrade.com/mb-Biost...

E6500 not listed for version 7.x, 8.x
http://www.biostar-usa.com/app/en%2...
.........

"CPU TDP over 65W is not available."
http://www.biostar-usa.com/app/en%2...

In other words, you can't use a CPU that draws more than 65 watts - doing so will damage your mboard, and Biostar does not list any CPU that does draw more than that.

BX80571E6500
http://www.cpu-world.com/CPUs/Penti...

It draws 65 watts, but there may be some other reason you can't use it with your mboard.

There is only one bios update for the 7.x , 8.x versions, that may be the version you already have, and it won't make the mboard capable of recognizing the E6500 CPU.
.......

"3) Patriot 2GB 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Desktop Memory"

I asked you for it's part number, not it's description.
Some memory manufacturers make several versions of their modules of a particular PC2 xxxxx / xxxx mhz spec, with different ram timing numbers and voltages specified for them, and sometimes different memory arrangements on the individual chips, especially for PC2 6400 ram and up.

Patriot does not list any ram for your model.
http://www.patriotmemory.com/config...

The closest is G31-M7 TE and they don't list any of their modules for that either.

PC2-4300 PC2-6400 PC2-5300 DDR2 SDRAM DIMM 240-pin
2 ram slots, max 2gb modules per slot.
Chipset : Intel G31 Express, 1333 FSB

When a ram manufacturer does not list modules for your mboard model, there is no guarantee that it will work in your mboard properly - it might work fine, BUT it might not.
......

"4) ZOTAC GeForce 7200GS ZT-72SEG7N-HSL Video Card "

Minimum power supply requirements for the Geforce 7200GS video chipset:
250 watts, some say 16A , some say 18A, at +12v .

It appears the Geforce 7200GS video chipset does not require a power socket on the card for more power from the power supply.

You could have chosen a lot better, for starting at not much more money. That may not be much better the the Intel 3100 onboard video.

sorry guys, dumb error on my part... did you know that if you don't plug in the 4 pin power supply for the cpu, the computer wont work? who knew?
