new build read the new thread about out of case test and no video

[Landbarron]

Well we put together the motherboard as instructed in a thread posted on this web site, and ran into trouble. We put the motherboard on the box as instructed an installed the CPU, RAM, Video card, hooked up the power supply as instructed.

We then plugged in the keyboard, mouse, and monitor, and when we jumped the two power connectors it powered up the heat sink fan on the CPU and lit up a green light on the motherboard, that indicates in the manual that he power is connected correctly.

The monitor did display an analog signal box that just floated around on the screen as if it were not getting a signal, so we never got the bios screen. That’s when we powered down and wrote this post please give some advice and help as to what to look for and what to try next. Below is the parts we are working with so far.

M/B: Asus M3N-hd/hdmi nForce 750a SLI Socket AM@=MB

Cooling: Thermaltake Ruby orb CPU Cooler for AMD or Intel

Memory : Corsair TWINX 3062 PC 6400 ddr2 800 MHz

PSU: OCZ/StealthXStream/600 watt/ATX 129mm fan/ SATA-ready/PCIe Ready/Active PFC

Video cards: (2) XFX GeForce 8600 Gt XXX 256MB PCIe w/Duel DVI ( Don’t know if it needs its own power supply, no cable came with it and there is no instruction referencing one in the manual it came with)
http://www.tigerdirect.ca/applicatio...rkey=p450-8650

Standard Keyboard, stole it from a another comp in a bedroom so I know it works same with he mouse.

Monitor is a Samsung 19 inch flat screen with DVI hookup
Soon as we get past this problem we will install all parts in case. We did see an updated out of case build and followed it, but we didn’t seems to do anything wrong, unless we didn’t hook up additional power to the video card and we can’t find any reference we need to?

Do you have both the 24pin ATX power and the 2x2 square power connections in place on the motherboard?

Your video cards don't need extra power. Try booting the system with just one at a time if you're not already.

[Landbarron]

Definitely not what is it?The 2x2 connector i mean.

[Landbarron]

we only used one video card

[Landbarron]

Does it matter what slot we put the ram in?

[Alaron]

The square connector is behind the keyboard/usb ports on the board.

You should put the RAM in the first DIMM to start. But you can try others.

[Landbarron]

The square connector you refer to seemed to fit in right next to the atx power suppy plug. there was four pin recepticle that it fit into with out any problemd I have no trouble with the usb stuff did I put the connector in the right place? We have not tried to power up again probably wii play with it in the morning

[Landbarron]

What is the best slot to put thee first video card into the PCIEX 16 1 or the PCIX16 2

[Landbarron]

Found it right where you said it would be and moved it to that plug

[Landbarron]

Put it where you said it would go and when we powered up the board it did nothing ,not even turning on the fan on the CPU.With out it pluged ,in it will power up the fan and we are right back whrere we started.What is the 2x2 next to the ATX power suppy socket right next to it?

[Alaron]

Ok, now that the power connections are in place and it still doesn't boot, you'll need to swap parts in and out to determine what component is not working.

Try each video card individually in the first PCI-E slot. Try each stick of RAM individually in each DIMM slot.
Then try to borrow another power supply.

Let us know.

[Landbarron]

When I plugin the 2x2 it stops the fan on the CPU?

[Alaron]

According to your motherboard manual, you must have both power connections for the system to boot. If it won't I would try another power supply.

[Landbarron]

If I have the power supply that I bought and plug both the main ATX power plug and the 2x2 in the ATX 12v then it wont even power up the board.If I unplug the 2x2 it powers up but if i try to plug it in while its runnung it shuts down the whole deal?Will try a new power supply.

[liambl]

So what you are saying is, you first plugged the 2x2 pin next to the big ATX plug? If you did, thats putting 12 volts into a 3.3 volt circuit, I'd say the motherboard is toasted.

[Landbarron]

yep we did try that before we realized it went where it is supposed to.

[Landbarron]

Well after all your help and a little more reading og the manuals that came with the parts ,we have replaced the M/B.Can't help feeling foolish so Ill share my experience,in a nut shell,READ the whole Manual before you start.All we needed was there,just got impatient. Thank you all so far.....But I'm sure we will be back with a little cry for help....hopefully nothing serious....LOL
