new graphics card NVIDIA GTX750OC is not working... advice?
-
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:

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.
Without prolonging the thread too much I just wanted to mention that I have an nVidia card which requires an additional plug from the PSU; however if you do not plug in the extra plug, the system will still boot into windows just fine. You then get a friendly reminder/warning when you log in from the nVidia driver that the card cannot achieve peak performance without the extra power. But it works just fine for non-game stuff. So I'm putting my money on Paul's theory.

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. You like that? You go right on staring at it. I prefer looking at galaxies. -- Sarah Hoyt
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.
My plan is to live forever ... so far so good

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.
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!

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... X|

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

You are just showing off! :laugh:

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...
Skipper: We'll fix it. Alex: Fix it? How you gonna fix this? Skipper: Grit, spit and a whole lotta duct tape.
I won't be able to borrow it from anywhere, but it looks like someone has posted a video explaining the steps to get it working so I'll get the PSU, and make the testing, let's hope it will work.

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...

That's what I thought... I've checked it with our electrical department and those sparkies have ensured me that unless I make strange things with the cables no issues should happen installing a bigger PSU...

Hello again, Joan. I just looked at the nVidia site and didn't see a product with the exact nomenclature you mentioned. The ones I see are GTX 570 and GTX 750 Ti. I get "Page Not Found" for the Ti version. You should check the amperage for each voltage on the power supply and not just total combined power. The installation manual for the video card might say something like +5V @22A. If the current power supply only delivers +5V @10A, then there is a 12A shortfall and the card will most likely not work with that power supply. Regards, Rick
Interesting and important detail, I'll have to check it before getting a new PSU to ensure this won't be another issue. Thank you! :thumbsup:

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.

How nice it was X| I'm almost sure it should work as I've seen somebody with the same problem for a GTX750TI card which is a little bit better than my inlaw's one mounted in the same computer than my inlaw's... I truly hope this will do it. Crossing fingers here... Thank you Dave! :thumbsup:

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.
This is what it looks like... let's see what will happen after this weekend...

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.
This is not the current reason as the computer is not passing the BIOS POST screen... Probably this is what will happen after the HW issues will be solved... 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.
If there were lots of things there I would test it but only disconnecting the DVD probably won't make any difference... X| Anyway I'll make some testing before getting the new PSU.

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.
Hi! I won't be able to test the card in any other computer, and it looks like there is a compatibility issue between the motherboard and the card itself plus not enough Watts from the PSU... so I'll have to change the PSU and then do some tricks I've seen in a youtube video where they explain how to make it work with his motherboard... X| X| X| Thank you for your post!

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

I can't imagine how someone without any kind of experience with computers can get this kind of things working...

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.
Yes, after reading a lot of posts here I've become aware of how the PSU's work +/-. Thank you for your recommendations! :thumbsup:

Gaming computers usually start at 700-800 Watt Bronze. http://www.newegg.com/Power-Supplies/Category/ID-32[^]
Probably I won't need that amount of Watts, but let's see what we can find at the shop this weekend. Thank you!

THE...PROBLEM...IS...THE...PSU. REPLACE...IT. PERIOD. END...THIS...PAINFUL...THREAD.
As far as I've seen, the PSU is one of the problems. It looks like the GPU needs at least 400W and the current PSU has only 300W. This is clear. Now, after some nice posts of other :bob: members I've known that there are other details that are important regarding the PSU capabilities which I'll double check at the shop this weekend. But, there's always one but, this is 100% sure not the only problem. After receiving some answers, I've seen that the motherboard installed in that computer has strange compatibility problems and that I'll be forced to update the BIOS from 7.13 to 7.16A which is the latest version from 2012 and even after doing that I'll have to make some extra steps to make it work. Now, I'm curious: why you are shouting? why this was a painful thread? :confused: This community is great to get help and again it has proven that it works wonderfully well to provide it...

Nope, this will be the second set of problems (software ones) now the computer is not capable to go after the BIOS POST screen, therefore the OS drivers are still not the issue... Thank you!
