Do I Have a Bad Card (GTX750Ti)?

[gpking]

I just bought a refurbished GTX750Ti to replace my antiquated GT520.
Since I own an HP, I ran through all of the b.s. to make my machine accept the 750, and that seems to have been done successfully (considering I can now boot Windows with the "foreign" hardware).

When I have the 750 inserted, I get no video. Whether I am plugged in to the card itself or the integrated graphics, there's no video.
Windows boots normally and I can login, I just can't see anything.

When I remove the 750 and leave my monitor plugged into the integrated DVI, I get video.

I really don't understand what is the issue. I want to say the card is bad, but why would that prevent my integrated graphics from working?
Since the card is refurbished (purchased through Newegg) I can't rule out the possibility it is bad.
I have no other computers to test the card in, so I am screwed there.
The card requires no external power and the fan runs like it should, I just get no video.
I've only ever upgraded two other HPs with graphics cards but I've never had this much trouble (they were all plug and play!!!)
All old Nvidia drivers have been removed prior to this.
Mobo is from Pegatron and is listed as "compatible" on pc-specs.com.

I'm a novice so I have no idea if I'm missing something or if I just got screwed.

some models of store bought computers [dell.hp,acer,ect..] may come with a ''locked or fixed'' bios and may not allow you to change certain hardware as a video card.. this is done to protect them from undue warranty claims and refunds .this is not done to hurt you but to protect them. you really need to see if that upgrade has been proven to work in your model first before you invest money in it .. there are a lot of these threads here at toms to look at some models will allow upgrades and some dont.. and a lot of guys here say ya ya ya when is really no no no...it would be sad you spent $200 on a card that wount post after you installed it as most find out. then get told its your psu and you spend more and end up right back where you are now, but its up to you good luck..


you got to know the the boards in these computers are not like the ones we use to do custom builds witch are open to upgrading with in the boards compatibly . the bios is custom made for there design and just for the parts they authorize to be used on there computers there only guaranteed to work as is out of the box as you bought it ,..

I guess it's not compatible then. I have only ever swapped 600-series cards into these machines and it appears as though a 700-series is too new to work.

I guess I'll RMA this guy as long as the return fee isn't too great and try a comparable 600-series card.

I just don't get why I am getting no error beeps like other people have reported.

you may google it around and see if there a ''trick'' to get it going .. prebuilts can be real funny on this card upgrading [or any upgrading ] ...

like I said they sell computers and you upgrading don't make sales for them guy's -- you buy them -you use them - they don't work well anymore - you chunk it in the trash - you run back to walmart and get there newer more updated one and repeat...

Actually there is a trick- MSI's N750TI TF 2GD5/OC variant of this card IS compatible with older Win7 HP machines like mine.
Your standard 750Ti requires a newer UEFI "version 8" BIOS to boot properly, but Win7 HP Pavilions use a legacy "version 7" BIOS (no "official" BIOS update is available, but some users have had success updating to version 8).
The MSI N750Ti has a microswitch on the board which allows you to switch BIOS modes between UEFI and legacy depending on the application (yet they don't readily advertise this feature).

Like the normal 750Ti, the N750Ti requires only 60W of power, so it is plug n' play in an HP Pavilion like mine.

For anyone in the same boat as me, order this. You can see from a few reviews that this DOES work in Win7 HP Pavilions: http://www.amazon.com/MSI-Computer-Corp-N750TI-2GD5/dp/B00I6DLIB8
Bear in mind this card is longer than some other 750Ti's.


I never cared to learn so much about the BIOS in my life!

good deal , any info helps to get someone going

so then I assume your card is now working 100% fine??

I got my N750Ti amazingly quick.

Unfortunately, it is not working.
Now I am getting video (whoo!) but my computer locks up at the splash screen.
At this point I either get an error code (PSU error, CPU error, memory error, etc) or it just hangs and crashes after a minute.
Removing the N750 allows the computer to boot normally.

I have tried both dip switch positions (legacy and hybrid) and neither works.
I'll restore my BIOS settings to default and start from scratch.
Hopefully I haven't opened up an even bigger can of worms than I already had...

prebuilts and upgrades blow. I never recommend them ..

good luck

Apparently no 700-series Nvidia card is compatible with an HP Pavilion H8 running Windows 7 because of the BIOS. That's it. Just the BIOS.
No decent 600-series cards are compatible either because of the power requirements.
That rules out any room for an upgrade, so anyone with an H8-11XX, there is no way for your to upgrade your graphics card without replacing the motherboard.
You can search for hours on end and read thread after thread of people having the same issue, but you will not find a solution.

It's really a shame this build is completely ruined by it's god-awful graphics hardware.
One piece of dated hardware means I have to build a whole new PC.

On the bright side, I already have an N750Ti to build around.
Wish me luck.

pretty well covers what I said in my first post here to you
