Hi -

I have just built a new PC - AMD3000XP mobo.

Put all the bits in and connected it all up. When I switch on the power the PC comes on but I am getting nothing on the monitor.

The monitor is plugged into the video card - nvidia gforce MX.

The case I ordered has a 300W power supply - which I thought was standard but looking at the other thread about booting up it seems 300W is a bit low. However - doing the power wattage calculator which was linked by Richard (thanks) - it looks like 300W should be just about OK. If not, why do the vast majority of cases come with a 300W PSU?

Anyway - any suggestions on the next move on how to get into BIOS much appreciated.

Thanks in advance.

One possibility, can you hear the disk drive starting up ? If the IDE cable is reversed at either end the motherboard just locks and nothing happens. Most IDE connectors, socket & plug are keyed, but some are not.

...or you may have an on-board VGA adaptor that needs disabling with a jumper change. Can't tell you for sure I cannot find a reference to the motherboard model you're quoting (not on Google as least).

Wedge,

Could you give us greater details on your new system. Please list all the hardware, OS, and Power Supply.

I really need the list of hardware (including - Mobo, RAM, CPU, Vid Card, PCI Cards, HDs, Optical Drives.) and the amps on the 3.3v, 5v, 12v RAILs and the Max Combined Wattage for the 3.3v + 5v RAILs. It should be on the sticker on the side of the power supply.

That would give us a complete picture of your system.

Take Care,

Richard

Thanks for the replies guys:

Sounds interesting - there is an onboard VGA adaptor, so this could be the problem. Don't know how I would change the jumper settings though? Could I just remove my video card, is the onboard one better than what I have? (see below for spec)

Thanks again.

The OS is Windows XP - once the PC boots up hopefully the OS should fire up as on my previous system as I have taken the old hard drive out.

Once I get this sorted I will probably upgrade the HD.

It looks like your computer is trying to use the motherboard video adapter. You can disable it in the BIOS (usually you hit 'del' when booting, before the Windows start up screen comes up). As to whether your video card is better or not, you'll have to give us the details of the video card you are using, but Geforce 4MX cards are not very powerful.

Wedge

Thanks,

But the problem is I can't disable it in BIOS because I can't see anything on the screen!

Presumably I will have to change a jumper setting on the motherboard?

I will try to get a better spec for the video card, it's about a year old though.

ORAC

That motherboard doesn't have any integrated graphics.

The present card may be the problem. Have a look at page 1 of the manual (10 Meg download!).

Due to it's age, I'm presuming your video card is an AGP 2x or 2x/4x card.

The AGP slot has 3 notches, 2x, 4x and 8x, but only supports 4x/8x (1.5V) cards as powered by the 4x connectors.

Some 2x/4x cards run on a 5V supply provided by the 2x connector and, if used, will stop the motherboard from working. Others, such as the Diamond Viper, have a jumper on the video card allowing it to be switched between 2x (5V) and 4x (1.5V).

Can you confirm the AGP rating of your video card, does the manual state the voltage, are there any jumpers on it?

(If it's a Gainward, from what I can find of their manuals, they require 5V.)

Wedge,

Your power supply is weak, but lets try a few things first. (You should look for a better power supply with at least 28a in the 3.3v RAIL and a Max Combined Wattage of at least 200W for the future.)

The nForce2 Chipset with integrated graphics has only one AGP Bus that auto senses an AGP Video Card. There is no option in the BIOS for turning off onboard graphics since it happens automatically. (You cannot have two video cards on one bus.) But that is not the case here since that motherboard does not have onboard graphics. (None of the Ultra 400s do.)



I am going to start with the RAM being the possible problem. If your RAM is not nForce Approved there is a good change you will just hear the Hard Drives Spin up but it does not boot.

Try removing all Drives, PCI Cards, and one stick of RAM. Try to see if you can get to the BIOS with one stick of RAM. If not try with just the other stick of RAM. (It would really help knowing the brand of RAM you are using.)

That board will support all GeForce Cards. If you have a TnT2 or older, it will not be supported.

Take Care,

Richard

Wedge

Thanks Richard, I will try that next.

The RAM sticks, despite being ordered from the same place within a week of each other, seem to be different manufacturers:

A-data & TwinMOS

Is that a problem?

Also, looking at PSUs, will this one do the job? -


Mercury PSU 400 Watt AMD/Intel P4

Product Description -
High quality 400 Watt PFC power supply manufactured by Mercury. Intel P4 & AMD Approved, Complies with ATX Rev 2.03, 12v Fan Fitted, Low Noise, over-voltage protection, CE , FCC, TUV, UL Approved, Dimensions 150L x 86W x 140H mm.

Wedge,

nForce is very picky about RAM. You should always run Matched Sticks and they need to be nForce Approved.

Only the TwinMOS RAM with the WinBond Chips is nForce Approved. Lets try one stick of RAM at a time and see if we can at least get you to the BIOS.

As for the Power Supply, I was looking for the amps on the 3.3v, 5v, and 12v RAILs and the Max Combined Wattage of the 3.3v + 5v RAILs. There should be a sticker on the Power Supply that looks like:



Take Care,

Richard

Wedge

Ordering a PSU online that data is not available unfortunately. Would you think a 400W supply would be likely to meet the specifications?

If not, do you know where I could order one in the UK that does?

Thanks.

Right - here is your next clue computer sleuths:

I did as you suggested Richard and disconnected all the disk drives and removed the A-data RAM (the suppliers are going to swap it for another TwinMOS stick).

Still nothing on the screen - but - I noticed that when I disconnected the CD writer/DVD cable from the mobo IDE port, they both started firing up which they were not doing before (ie by virtue of the fact they are both connected to the power supply).

Thanks again for your help Richard, I will owe you a few pints when this is sorted!

btw the fan on the video card is also spinning (I assume it was before but didn't check) - which I assume is a good sign!

Naples Air Center, Inc.

Wedge,

I am sure this is a RAM issue. Did you try with just the stick of A-Data? I am not convinced that the TwinMOS is a good stick of RAM. If you are going to swp out the RAM, have them give you a matched pair of Crucial RAM that is on the nForce Approved List:

nForceTM Memory Compatibility

As for the power supply, not all Power Supplies are created equal. You will need to look inside the case to find the sticker on the power supply for the information I am looking for. (Since you have an older GeForce card, power is not as critical as someone running a new GeForceFX card pulling 75W for the Vid Card alone.)

Take Care,

Richard

Wedge

OK.

I will try the A-data RAM (was just about to send it back!)

The info relating to this power supply I posted above, ie:

3.3v/16A, 5v 20A, 12v/10A


16 amps on the 3.3 RAIL etc.

.......I have tried the A-data RAM on its own and still no joy I'm afraid.

Crucial technology RAM does not appear to be on the list that you have linked?

I am going to swap out the RAM for two matching sets. I have another supplier that does crucial technology.

Thanks again for your time.

Naples Air Center, Inc.

Wedge,

Your power supply is weak. The 400W Antec Power Supply I listed above has these numbers:

3.3v - 28a
5v - 38a
12v - 18a

Max Combined Wattage 3.3v + 5v = 240W

For the future, it would be a good idea to look at getting a new power supply.

Right now, lets see if we can get the motherboard to boot.

Once we can get to the computer to boot I would like you to configure the computer like this:

Motherboard
CPU
RAM
AGP Video Card
1 Hard Drive on Primary Master
1 Optical Drive on Secondary Master
Keyboard
Mouse
Monitor

That should be enough to get your computer to install Windows without having Power Supply Issues.

Crucial is owned by Micron. It is their RAM. (You will find Micron on the list.)

Take Care,

Richard

Wedge

After talking to the supplier, I have tried the motherboard again with one stick of RAM, checked the heat sink is attached properly, checked the CPU is not damaged etc etc etc.

Then I tested it again with a minimal setting outside the case to check the board was not shorting on the case.

No joy.

Also checked the graphics card to ensure it was not damaged in the changeover.

Looks like I have a duff motherboard, which would be unfortunate for a first attempt at a PC build!

So I have rebuilt my old system and the mobo is going back to the supplier!

Thanks for all your suggestions.

Wedge,

Sorry to hear it was a bad motherboard. (If the mobo is bad. Proper RAM with nForce is critical.)

Let us know what happens when you get the next motherboard.

Since you are sending the motherboard back, see if they will trade it in for an MSI K7N2 Delta-ILSR or an ASUS A7N8X-E Deluxe. (Both those mobos have Dolby Digital SoundStorm and SATA RAID. Good features for the future.)

nVidia's SoundStorm blows SB Live! away.

Take Care,

Richard

goates

One thing you should be aware of if you want to use the SoundStorm audio on an nForce board is that it can only be used with digital speakers. If you use the analog speaker ports you only get audio from whatever cheap onboard audio system the motherboard manufacturer included which are worse than the SB Live! card. This is something that I never see mentioned when talking about SoundStorm audio, even on nVidia's site.

I've been using OCZ RAM with my Abit NF7-S nForce2 motherboard and haven't any troubles with it. It doesn't appear to be on the official nForce compatiblity list, but it was tested by Abit.

goates,

I use the Logitech Z-680s for SoundStorm, MP3s and DVDs do sound fantastic on them.

'Twas, not surprisingly, my mistake in the setup.

I did not know that new PCs had two power connectors. And I had omitted to connected the 2nd.

Still it's worth posting it here for anyone who does not know!

It's working fine now, and thanks for your help.
