    X| X| X| I don't think they'll want to recycle the board... Too much money involved to play a couple of games. And I don't think the shop will agree returning the GPU... How nice!

    Yeah - not nice... Do you have the opportunity to borrow a PSU with 400W? You may check it with that... Jochen Arndt may be all right that the problem is at the power-on state, when all moving parts are spinning at top speed...

      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. X| 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! :thumbsup:

      Summary: It's a relatively modern motherboard and chipset, the slot type is backward compatible, just make sure it has adequate power. Details: If the card recommends 400W, I wouldn't mess with that. It will need 400W. For 300W, at best you'll get it to boot up, but it will crash and lock up for no apparent reasons. At worst, it won't boot. Yes, PCIe 3.0 IS backwards compatible, it's not just a theory. As another poster mentioned, boot in safe mode, uninstall the old driver, and delete the drivers. Place the new card in, with an adequate power supply. If there are auxiliary power ports on the video card, make sure they are supplied with the extra power they need as well. Power it up, the system should detect the card, and if it doesn't have drivers you will need to manually select from the install disk. One problem I had when installing a recent video card was the hardware ID of my card was not in the approved list of drivers, so it would not appear for me to even be able to manually install. I had to modify the driver's INF file and perform some other wizardry. If it comes to that though, check back. Finally, a bios update is always a possibility, however, I have only ever had to resort to a bios update if I found instabilities in my machine, and the bios update indicated that it might fix the issue. The bios update is the LAST thing I would attempt. Regards, Paul

        Hello Paul! Thank you for your comprehensive steps list. I'm afraid that after installing the new PSU, the problem will still be there: @Kornfeld_Eliyahu_Peter has posted this link to a youtube video in which the same problem can be seen... : https://www.youtube.com/watch?v=fkBTSlBW2oc[^] So... I think the only real options are: 1. Return the GPU. Which I don't think it will be possible at all. 2. Buy and install a new PSU and follow all those steps... which is a PITA each time the computer must be started.

          Yes, but it is not just the PSU wattage you need to look at, you need to make sure the various power rails supply the amperage required. I had a similar problem a few years back, and although the PSU was technically sufficient, there were a number of 12 v rails and they weren't rated to supply the juice to the gpu plugs.

            As I read the first sentences of your issue I thought immediately that it was the power supply. I've experienced this same issue with 300W and needing more powerful one. Same thing fans seem to turn, lights up but nothing from computer. I believe that really is the issue. Good luck.

              Don't know if anybody has said this, but it might be the graphics drivers from the old card?...try booting in safe mode by multiple pressing the F8 key while the computer boots, you should see a Dos style menu come up that will let you choose Safe Mode (choose no graphics drivers if it gives you the option). If you can get in safe mode, un-install the old graphics drivers and reboot back to normal mode, then install your new graphics drivers and software for the new card. Not 100% sure that's what it is but if you have tried all the hardware things, it might be it.

                High end GPUs have cables directly to the PSU.

                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 ;P

                  If possible disable the onboard graphics card. That might save some wattage, but I doubt it would be enough.

                    I'm positive that it was disable by default as the computer came with an external GPU installed a terrible one but... Anyway the new GPU specs are claiming it needs 400W which the current PSU is not capable to give... X|

                      If there are components that you can unplug to temporarily lower the power draw, then try that. Additional hard drives, DVD-ROM etc. If that works then you will know that the PSU isn't beefy enough and you need another one.

                        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...

                        Why not ??? The card draws the supply it needs, the more available, the better, but you cannot fry a motherboard because of a stronger power supply...

                          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.

                            Ok those are my ideas: - Can you try this card in another PC, it could be a damage Video Card. - I smell that you can have a compatibility issue, try to check if you main board chip-sets are compatible with this Video Card. Not sure how old is the main boards, it could be just a setting in the Bios. (do it before plugging the Video Card) - Try the 400Watts +, maybe that is all you need.

                              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.

                              Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason? Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful? --Zachris Topelius Training a telescope on one’s own belly button will only reveal lint.

                                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. X| 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).

                                Simple Advice: NEVER help friends or family with their computers! :-))) Honestly, it sounds like putting a new Power Supply in there will work fine. The Wattage is the maximum output, not the amount of power FORCED into the system. It will simply let the video card draw the extra power it needs. ($30-$60.00) Considering your time and what the adapter costs. The power supply is probably the fastest simplest way to wrap this up. I jumped into this thread because after Microsofts Update, a few programs started misbehaving and I had to install 7 different versions of my AMD RADEON driver to find a stable one... I was thinking I was not alone... LOL

                                  Probably. Its likely drawing so much current at some voltage that its drooping too low. If it has a connector for the power supply to directly connect to it, you'll want to connect that too -- sometimes the traces on the motherboard just can't supply the kind of current a graphics card needs. Even if you can get the card to work with his current power supply, you probably want to upgrade it. When he pushes the thing really hard, it could draw enough to cause the system to be unstable. FYI, a graphic card's power supply specs are not because it needs that much power itself, its usually because PSUs of that class have sufficient amperage at some needed voltage. That's too fiddly to be worth the trouble, but if you know how to check it, its worth doing -- not all PSUs of a given wattage class have the same voltage/current capacities.

                                  We can program with only 1's, but if all you've got are zeros, you've got nothing.

                                        It's been a while since I have done a lot of work with graphics cards (and I don't have time to read all the posts, maybe this was already suggested.) Have you tried putting the old graphics card in, firing up windows, and switching to the generic VGA driver (can you still do that with newer versions of Windows?) and then putting the new card in?

                                          This may help. https://www.youtube.com/watch?v=fkBTSlBW2oc[^] This guy has the same problem as you and he's got a 600w PSU. It seems to me to be an incompatibility between the HP bios and the nvdia card.
