New build will not boot monitor

The new build:

Gigabyte GA M57SLI-S4 SKT AM2
AMD Athlon 64 X2 4400+ Socket AM2
Innovision 3D 8500GT 512MB DDR2 VGA DVI PCI-E
2 x Crucial 2GB kit (1GBx2) DDR2 PC2-5300
PSU: Extra Value Gold 750W Silent PSU - 12cm Fan, 20+4pin, 2x SATA, 1x PCI-E
Pioneer BluRay DVDRW (2 months old)
500 gig Seagate IDE hdd (6 months old)

The first problem was that the original PSU was doa. I tried an older 350w psu to see if the build worked and that would not boot the monitor. No surprise really, I thought, and awaited the delivery of replacement.

This arrived yesterday, installed it, system posts etc, but monitor would not boot. I have tried this with both a tft and a crt, both of which I know work. I have changed cables. I have used a motherboard tester card, which informs me that all is well.

The fan spins on the graphics card, but am I right in thinking the card could be faulty? Or am I being spectacularly dim, and have missed something basic?

Any help and suggestions would be, as usual, very gratefully received!

Cheers all!

What kind of connectors are on the back of your VGA card?

DVI, VGA, HDTV connectors

These are the specs for the card:

Chipset - Geforce 8500 GT
Memory - 512MB GDDR2
Core Frequency - 460MHz
Memory Frequency - 667MHz
RAMDAC - 400MHZ
Interface - PCI-Express
Memory Bus - 128-bit
Stream Processors - 16
Max. Resolution - 2560 x 1600
Output - DVI, VGA, HDTV

Do you have a friend with a motherboard that has PCI-e?? If so, try the card in his rig. Also, how are you hooking your monitor up to the card? (VGA, DMI or HDTV).
If you're using an adapter to connect you monitor to the DMI port, do you have the correct adapter?? You could also try going into the bios and make sure the type of graphics card is set to PCI-e. Granted, most motherboards will detect if it's AGP, PCI or PCI-e, but there are some out there that are really picky. I'm not sure if that is one of those boards.

Originally, I was connecting via VGA, then used the adaptor which came with the mobo to the DMI port, so am assuming it is the correct adapter. Since I do not have another graphics card to use with the mobo, I cannot get to the BIOS to ensure it has been set to PCIe. Perhaps the best thing to do is to test the card on another pc...

And then send the bugger back to ebuyer as doa!

Thanks for your help, mate.. much appreciated!

Did you make sure you connected the power supply cable to the gfx card? I'm pretty sure it has/needs it's own ps connection. (usually a 4pin molex, but it might be a 6pin)

Yep, you are right, and it was connected!

See, this is exactly what I need........ troubleshooting. I've been looking at it, going away, looking at it again, and perhaps I have been missing something obvious.

Whole thing is maddening!

Cheers matey!

So it WAS connected and thus it still doesn't boot?

Make the cpu ps connection is there (same thing a 4 pin molex very close to cpu).
Make sure mobo isn't grounding on the case somewhere. Sometimes the best thing is to take it out of case and put it on the anti-static bag and fire it up from there.
Try removing one stick of ram and then the other. You sure that mobo takes DDR2-5300? (I'm pretty sure it does though).

How do you know it posts alright if you can't see display? You hear one good beep?

Those series cards do not require a power connection. The AGP cards required a separate power supply (4 pin connector) while the 8800 GTX and 8800 Ultra required the six pin molex connector.

ok, I have now tried THREE different graphics cards, and I have checked them in another rig (they all worked perfectly). I decided that the mobo must have a problem. Returned it to ebuyer, and they cannot find a fault with it.

So I now have a rig that will not fire up a monitor - ANY monitor.

The latest graphics card is Sapphire HD 2400PRO 256MB DDR2 VGA DVI HDTV out PCI-E Graphics Card

Does anyone please have any ideas as to how I can get this rig working??

What did? The new Power Supply?

I would say it is most likely the power supply, but if you have changed it already then it's either the new PSU is faulty, or the M/b is.

josbd did I read correctly, member since 2003. ?

If you have hardware experience (and it sounds as though you do)
I'd recommend bench testing fully (with as much detached as possible)
You may also want to re thermal paste and mount the CPU again.

Make sure all cables are out (including harddrive) whilst bench testing

It can still be doa PSU mind you

Apols: this prob has been going on for quite a while. The original psu was completely dead. This one at least spins up and puts out power, lights come on on the mobo, and the fan on the GPU spins. All seems to be perfectly in order, apart from the one little problem with powering up the monitor.

Will give it another go with nothing in the thing, replace one bit at a time, reset the CMOS etc etc............ This is the most frustrating build ...... EVER!!

Thanks for your help mate, and erm aye....... 2003. I should know better!!

ok, tried the above, one component at a time. CPU spins up, gfx fan spins up, still no monitor boot. Sits there, amber light motionless.

One suggestion has been that the PSU isn't good enough. I know these budget versions often operate at less than the claimed wattage, but surely if the rails are 20v then at least the monitor would boot? PSU claims to be 750w.

I have a very expensive doorstop here. Can ANYONE see why this rig will not boot the monitor?

It must be the motherboard, some online shops have a habbit of saying that they cant find a problem with the hardware even when its clearly not working. One of my friends bought a harddrive online and when they got it, it didn't work in any computer, however when they returned it to the online shop they said it was working fine.

You may well be right, there!

Well, I am awaiting delivery of a new mobo analyzer which should arrive in the next couple of days. Hopefully that will find any probs.

The PSU suggestion is still bugging me tho. Aye it's a cheap one, but it spins up and sends power to the graphics card etc, surely at 750W it should be able to boot up the monitor?

Yeah thats easily enough power, have you tryed pluggin in only the motherboard+CPU no RAM it should beep if its working to tell you that there is no RAM.

Are you getting any beeps at all from the BIOS? How can you tell it POSTed ok with a black screen? Do you hear at least one beep (short single beep means it posted ok). If no beep, then it might be a dead CPU or dead RAM.

Check that you're not grounding the mobo to the case.

try resetting the bios, i had this yesturday.

right off the bat, you are not using a powerful enough PSU. Most newer systems need at least 450W.

Stop building a nice system only to ruin it with a cheap and underpowered PSU.

google PSU calculator, plug in your requirements and then add 30% to the results. Then buy a quality PSU with the wattage you calculated + 30%
