My new ASUS GTX 750 Ti is not recognized

[FiftyOneFifty]

I bought a GTX 750 Ti expressly because this series is supposed to work with OEM (Dell, HP, etc) and PSUs and not need any other power connectors. Imagine my surprise to find a six pin external power connector on top of the board (nothing on the New Egg or ASUS page indicates external power is required).

I swapped the PSU that came with the HP dx2400 Mini Tower with a 430 Watt Corsair I keep as a replacement unit for customers. The video card is still not recognized. The motherboard is an IPIBL-L8 ASUS made for HP, I don't know if they sold it direct to users, and I can't find a manual for it online (HP seems to have no resources forthe dx2400 either.

I get no video out of the DVI or VGA ports on the card, internal video still works, and the BIOS setting for video gives priority to the PCI-e x16 slot. I find no jumpers on the motherboard for selecting video source. The fans on the video card spin at least. Drivers won't install beacause they can't find an ASUS product.

I do have an older 550 Watt PSU from my old P4 gaming rig, I'll try that. Thanks for any ideas.

I'm going to wait to see what you get with the other PSU. Fans powering on doesn't mean it's not a power issue. The board definitely is not picking up the GPU if you're still getting on board video with it plugged in. According to the info on that MB, "*Integrated video is not available if a graphics card is installed". A failure with a 2nd PSU could point towards a DoA GPU and not a MB issue. The only other test is to put the GPU in another machine and try it there.

Jake, nope, no better with the 550 PSU. Time to RMA, I guess. I don't have a second machine to try it in. BTW, where did you find info on the IPIBL-L8, i came up with nothing?

It was a educated guess but I was going off the MB being IPIBL-LB not I8. It's a ASUS MB used in HP computers and it seemed almost like a misread while looking at the model number, god knows I've done that a lot trying to look at stuff in my case.

RMA is probably the best option. Sure you can get another one and it not work either, but if you RMA you're just out time and not having to eat cash trying other things. I have experience going the other way and it sucks. Bought a GPU some years back, didn't work. Paid out for a new PSU, then MB (which needed different RAM).. only to realize it was simply a DOA GPU lol.

One more thing to try, though I would think if the card was working, it would preempt the onboard video during POST. I bought the system used on ebay, (as I said, I thought 750 Ti's were supposed to work with OEM mobos and PSUs). The license that came with it was for Windows 7 Enterprise. I can't imagine it makes a difference, but I'm downloading an image of Home Premium from Digital River to try instead.

While I don't see any way that one version of Win7 would work while the other doesn't, there's is a reasonable chance that a clean install would help. There's always a chance that it's software causing the issue. BOINC has been a issue in the past with the way Windows has treated sound and video drivers ever since Vista came out as well as other services. Drivers always seem to be a issue as well and a clean slate can fix those as well.

Good luck and let us know how it works out.
