no vga out of GA-73PVM-S2H

Hewlett-packard / Pavillion a000?

Specs: xp, 512 (low, I know)
Hello to my fellow techs. There's trouble here in doggy land as I cannot get any video to show when I only hook up power/kb/mouse/vga to this board. I have carefully inspected the board's connections and all seems well and proper.

I am trying to follow up on someone else's work with this - someone who I have no contact with except intermittently through my cousin, whose pc this is.

Sorry for the vagueness here, but any questions and/or help will be very appreciated.

Anyway, back to the board. It is in an HP a1517x case. No extra addon cards, and with all seemingly unnecessary USB, Firewire, and audio for the front panel either connected or disconnected I still do not get any video output.

Where one of my problems lie is a speaker lead for this case - I don’t have one. The board has speaker pins but there is no speaker in this machine, not even an onboard piezo-electric type.

So I don't know if it is even beginning to post.

OK, so at some point the motherboard has been changed?

If so, have the motherboard drivers been installed?

Or, do you see absolutely nothing when you try to boot the machine?

Thanks for the reply Skip. You nailed it on the second go there with "absolutely nothing" when the machine is first powered on. fuss'n with cables makes no difference. this is with two different known good monitors too by the way.

Also, yes, the mobo was changed out. I was not around with the changeout, but came in to "clean up the mess" with as little tools as possible. always handy, eh?

So, no idea about drivers as no video = no knowledge of what the deal is with this box.

I also read in the manual that I dl'd for this board that the dvi-d port does not work with an adapter from that format to analog. I initially intended to just throw on the usual white adapter for that conversion but obviously had to bag that.

But I have yet to get even a hint of signal from the sub-d vga output. arrrggghhh.

I await the next educational opp on this particular scenario.

Take the board out of the case & benchtest it.

Thanks Jam, I may very well try that tomorrow in the daylight. I was just reading through the manual I dl'd from Gigabyte's site and read that: "To meet expansion requirements, it is recommended that a power supply that can withstand
high power consumption be used (400W or greater). If a power supply is used that does not
provide the required power, the result can lead to an unstable or unbootable system.
• The main power connector is compatible with power supplies with 2x10 power

I have a known good 20-pin psu from a dell dimension that I can also hook up to this board, but I need to look at wattage of that psu in the dell yet. If the above paragraph actually means that this board (sorry, I haven't even looked at the CPU's specs yet) req's 400w or greater to run it, and it only currently has a 300w in it, would this at all be a possible part of the problem?

I realize these numbers indicate the MAXIMUM rated wattage output, so I would think that pushing a 300w to run a 400w rated board would still show SOMETHING, but this is a question I look forward to getting answered here if anyone has an idea about it.

Thank you all for the continued help with this usually simple problem. I miss a good techie workplace where I could just take this in after hours and work on it with all the proper tools and space and equipment. But here at home I will sure try to do the best I can with what little I've got. (being unemployed really bites by the way). :(

Okay, I think I might've figured out why I don't get video out of this board. I just went to and checked out ram compatibilities for this board and they do NOT list 1GB 2Rx8 PC3200U-333. It's more specifically an HYS64T128020HU-5-A

Now, even though Crucial states that the board has a 4GB max on it, it it also states that the max component Density is 1GB. Okay. with only TWO slots available wouldn't that limit the board to only being able to have 2GB max on it?

Here it is cut and pasted from Crucial:

* 240-pin DDR2 DIMM Banking: 2 (2 banks of 1)
* Chipset: nVidia GeForce 7100
* DDR2 SDRAM Frequencies: PC2-4200, PC2-5300, and PC2-6400
* Error Detection Support: Non-ECC only
* Graphics Support: PCI Express x16
* Max Component Density: 1024
* Max Unbuffered DDR2 SDRAM: 4096MB
* Module Types Supported: Unbuffered only
* Supported DRAM Types: DDR2 SDRAM only
* USB Support: 2.x Compliant
* Although the memory can be installed one module at a time, the best performance comes from using matched pairs of modules.

So my question to you all is, becuase the ONLY ram chip I have that will fit this mb is only a 3200, is that too slow for the machine to operate? here is caveat #2: I hooked up a speaker connection to the board's speaker pins and pleasantly listened to the continuous long beeeeep, pause, beeeeep, pause, beeeeep. At which point I knew it HAD to be ram. I took out the ram but very oddly enough could not get another sound out of it. It SHOULD'VE been screaming at me about ram then too.

So, the two variables I have that are potentially troublesome here, with an entire lacking of a techie workbench at my disposal (being unemployed), are A.) a ram chip that is not stated anywhere to be compatible with this board, and B.) running a 300w psu on a 400w psu rated board.

Thanks for any and all help here folks,

Okay, never mind everyone. Thanks for tryin' with me, but my cousin threw in the towel so to speak. It went back today to the guy he got it from. I am posting questions on a new mb though to go in the same case the old one was meant for.

Thanks again,
