Yes, of course I will not update the BIOS if it is not needed... let's see what happens this weekend...
Thank you!

In my experience, BIOS updates are the last thing I'd try: I've only had to do it once in all the years I've been playing with PCS (and that was to use a large HDD that the previous BIOS didn't support)
And when I did it, it was from the manufacturers site and plastered with warnings to make sure it was the absolutely right model and revision of motherboard, and not to interrupt the power while the flash was applied, and that it was entirely my fault if the PC never worked again...
It did work again, and it accepted the bigger HDD.
Would I install a BIOS from a different manufacturer? Myself, no. Not unless I was absolutely sure that the new manufacturer "badged" it's product for HP. The BIOS is the software that talks directly to the hardware, and if it doesn't work exactly right...nor does anything else.
From a quick read of your other post, I'd go with the PSU first (or try the card in a "better" PC first to make sure it works) - but you almost certainly need to boot in safe mode or remove the "old" drivers before you upgrade to the new card.
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

100% agree.
Let's see what will happen this weekend.
1. change the PSU.
2. try the steps depicted in a youtube video that shows how to make it work in a quite similar computer.
3. try to extend those steps and make it easier for my inlaw to get it working.
4. just in case it is not working then I'll update the BIOS. And in any case I'll do it using the patch in the HP site.
Thank you OG!

I know this is "teaching your grandmother to suck eggs", but don't forget that you don't need a 400W PSU: if your previous one was 300W and the card is 400W, you're going to need a 600W~700W PSU to replace it!
But you knew that, I know.

Seriously?
My grandmother seems not to know how to suck eggs 
OK, 600W here we go!
Thank you OG!

If the computer previously used up to 300W, then it's going to want at least 200W to run the processor, ram, HDD's etc. So if you add a card wanting 400W then 600W is the minimum PSU you can get away with - do you know how much power the old card used? If not, then 700W is safer, or the computer may become unreliable when the card is running to it's full potential.

My last experience with a FOXCONN motherboard, was not a good one.
(side note: I will never buy one again)
When I did go to update my FOXCONN MB that I bought in 2012, I could not find anything useful from FOXCONN's site. As it turns out, the manufacture does not write the BIOS, they will use one of two, maybe three that exist.
I determined that I had an AMIBIOS installed on my MB. Then proceeded to get the latest AMIBIOS release for the chipset that I had.
[IMPORTANT]
Just so its clear, I downloaded the latest BIOS for my chipset from the company that wrote the BIOS.
I updated my BIOS to fix a sound issue that appeared after a graphics card update, go figure.
All answers pointed to a BIOS fix, which was not provided by FOXCONN. However, the manufacturer of the sound card, which was embedded on the FOXCONN MB, said a certain version of the AMIBIOS would resolve the issue.
I used that to update my PC, and all went well.
Again, it's the last thing that I resort to, because I have created more than a few bricks in my life (engineering samples from device manufacturers, not my own PC).

I've been using HP and IBM computers for a long time in our office, but as I do not need powerful GPUs, I've never faced this kind of thing (only upgraded memory...).
This situation is quite different and it has suprised me a lot, I double checked all the requirements with one exception which was the PSU power (I missed that one), but it looks like the GPU is not working as expected with my inlaw's computer.
Someone has posted a youtube link to a video of a freak-kind guy who has got it working by updating the BIOS (from hp) and making it to try to boot using PXE and network. After all that Windows 7 loads automatically without issues... 
I'll try to follow those steps and hope everything will work well.
And of course, I'll forget about updating the BIOS using the patches in the Foxconn page...
Thank you Paul!

Hello all,
My brother in law asked me about a recommendation for a graphics card that would work with his computer.
After searching for the computer tech specs and knowing the amount of money available I recommended him the GTX750OC card.
After removing his old card and inserting the new one, when powering the computer I saw all the fans rotating and in the display the blue splash screen that comes with the HP computers appeared (a hand and a small text down on the screen asking to press ESC key to go into the boot menu).
That is the last thing the computer is doing. you can press ESC or whatever but nothing happens.
After looking deeper in computer tech specs I saw the power supply was giving only 300W and that the graphics card needed 400W to work.
Do you think changing the power supply will do it?
After replacing the new card for the original one again everything worked again.
Any recommendation? (apart of course to stay away of relatives who ask for help in IT related issues).
As a recommendation of @Kornfeld_Eliyahu_Peter, I'm posting the motherboard kind here: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c02978278&cc=us&destPage=document&lc=en&tmp_docname=c04169254[^]
Thank you all!

Your card does not get power directly from the power supply but via the board, so the question: Will the board survive a new power supply unit?
You may post the board id here, someone may have an experience with it...

Alex: Fix it? How you gonna fix this?
Skipper: Grit, spit and a whole lotta duct tape.

High end GPUs have cables directly to the PSU.
|
|
|
|
|
I checked some models with this GPU from ASUS and MSI and didn't see such external power connection...Maybe the exact model would help...

Ok maybe it doesn't, but then it's not really high end anyway..
But 400W without cables? Madness
edit: ok I've found two of them, one says "no cables", the other says "additional 6 pin PCIe power required"
|
|
|
|
|
In their specs (at the card box) it says no extra cables needed, I asked that in the shop too and before buying I saw it in their web site... so they are asking for 400W without cables... Why should it be madness?
|
|
|
|
|
Because in that case you get power via the board, and it maybe can't handle it...

The 400 W is the recommended power that must be supplied by the PSU. It is not the power required by the GPU card.
Form the Nvidia homepage for the GTX750 (normal version):
Max. power consumption: 55 W
Min. PSU pwoer: 300 W
Your GPU seems to be an overclocked version ("OC") that might draw more.
The PCIe x16 slot is able to provide about 75 W. If the card requires more power, an additional connector must be provided.
Overall the card should work but the PSU might be at its limit when the GPU card is at full power.

And keep in mind that power supplies degrade over time. What started out as a 300 watt power supply may be down to 285 or less. The symptoms you describe sounds exactly like the time I forgot to plug in the extra power cables on one of my video cards (rookie mistake, I know).
Also, double check that the PCI versions are compatible. Some video cards may not be compatible with older revisions.
Finally, I'm not sure how it is now, but a few years ago, say 2005ish, HP and the other manufacturers had custom pinouts on their power supplies so keep that in mind if you're going to replace it.

Had not seen your post milo-xml, my idea was to go to the shop with the PSU under the arm just to check the connections and to be able to ask for adaptors if needed... 
|
|
|
|
|
OK, nice to know that...
I've been searching the Internet a lot to solve this and I've seen that everyone under the sun is recommending to upgrade the PSU at least to 500W to ensure no problems related to the PSU will appear... this should not be expensive and probably is the path I'll follow.
Thank you for posting!

I have 2 GTX760OC cards (SLI) in my gaming PC and they require 2 sets of power cables directly from the PSU. I had to buy a 1000w PSU to power everything.
Your card doesn't look too much older than mine, but maybe I'm just showing off

The PSU you bought is ridiculously oversized for the cards you've got running with it. At stock those cards are 170W; even OCed they're unlikely to be above 200W each. With a 100+W CPU and heavy OC the rest of your box might be another 200W. A 750/850W PSU would be more than plenty to run your system at full load (I'd learn toward the latter for headroom if your next pair of cards are significantly more power hungry), and would be much more efficient when your system is at idle. 1000W is overkill for anything below a 3way GPU or 2CPU 2 GPU system.

I also have 2 SSDs plus a normal drive, 32Gb RAM, and several more USB devices, not sure how much difference any of that makes. One day when my current 8Gb VRAM is no longer enough I can plug another 2 graphics cards in. The problem then will be that they will run at 8x, while I'm currently running at 16x. That's probably a question for next year though.

Not much. Mainstream processors are ~90W, top end ones ~130W; the 200W everything else figure I used covered a lot of stuff plugged into the mobo.
As for more GPUs; dropping from 16x to 8x won't matter for anything graphics related or for most compute tasks; the exception being if you're doing a lot of CPU-GPU IO instead of handing off large independent blocks of computation and waiting for the results back.
However, regardless of what you're using it for buying two more 760s next year would be a waste. SLI/xFire both scale much worse above 2 cards; to the extent that a few years ago I saw some tests showing that 4 cards wasn't meaningfully faster than 3 in most games and actually was slightly slower in a few. 2 cards to 3 still gave a decentish bump but it wasn't close to the 50% theoretical gain; generally for the same money 2 faster cards would beat 3 slower ones; making 3way setups only worthwhile when you'd already gone to the top normal single GPU cards (eg 780 but not Titan).
For compute, it'd still be a poor buy because GPU performance scales with moore's law, and two new cards would outperform 4 old ones while using a lot less power even if you could find another two 760s; which by then you probably won't. Used cards run the risk that it's people who run their cards the hardest that are most likely to sell; and from personal experience 2-3years of 24/7 GPU compute will kill a lot of cards.
