[SOLVED] EVGA 750 TI problems with Dell Optiplex 780 MT.

[James Eckmeder]

So I have a Dell Optiplex 780 MT and I recently picked up an EVGA GTX 750 TI to install into it, but when I turned it on, the PC kept trying to post but it kept failing. For the first two tries it gave me error code 1 3 4, but after that it gave me error 2 4 and it can't boot up. I researched and found that the issue could be because of my PSU, so I picked up a 550w PSU and installed it, but it did the same thing as before. I then tried upgrading the BIOS. I tried revisions A04, A12, and A15, but this didn't help. Can someone give me some help? (My current specs: Intel Core 2 Duo E8400, 10GB DDR3, 500GB HDD, AMD Radeon HD 5450.)

Did you uninstall the radeon drivers first? eg with DDU
Then install the nVidia drivers?
PSU make and model?
Does the PSU connect properly to the Dell motherboard?
What does error code 1 3 4 and error 2 4 mean?

 

[Ventrobear]

A little outdated but I budget game myself. Have you tried installing/updating any drivers for the graphics card? Can you try booting without the card? (or does your pc not have an input from the motherboard.)

The PC wont even post, it just gets stuck at the diagnostics giving me error 2 4, which is a GPU error.

 

[Ventrobear]

when you turn it on, are there any small leds lighting up? any fans spinning? or is it just no response at all.

The PC can't post. the PSU I have is the Antec True 550 550w. Yes, the PSU is connected properly. Error 1 3 4 is a hardwarw error, error 2 4 is a GPU error.

It starts up but fails the self-diagnostics with error 2 4, when I remove the card it works just fine.

Can you try another GPU in your PC?

Can you connect a motherboard speaker to the motherboard and see what POST/Beep code you get?
See https://www.computerhope.com/beep.htm - it most likely uses AMI bios.

My original GPU works fine, but then i put in the new one in, it does not. The PC does not make beeps, only diagnostics lights. In this case, lights 2 4.

 

[SteveRX4]

Then it sounds like your GPU is faulty.

Have you fitted a motherboard speaker?

Unless you know what 2 4 means then it's of no help.

It has a built in speaker, but Dell uses lights instead of beeps. And error 2 4 is a GPU error. https://www.dell.com/support/articl...e-dell-optiplex-diagnostic-indicators?lang=en

 

[SteveRX4]

So with the old GPU, do you still get error 2 4?

Nope, only the new one. I have seen videos of people running this card in this same PC. So what gives?

 

[SteveRX4]

It seems like you have a faulty GPU.
Can you try it in another PC?

 

[Ventrobear]

I've found some manuals and it turns out that it means, "a possible graphic-card failure has occurred". I agree with SteveRX4 on this one.

I don't have another PC to test it in.

I know what the error means, im just questioning why it wont work if ive seen other people use these same cards in these same machines.

 

[SteveRX4]

These same cards maybe. But not your particular card - because I think it's faulty.

RIP SteveRX4. He got banned for reasons we shall not know. Alas, I would try buying another card to see if its a problem with the graphics card or something else within the pc. Most likely the motherboard.

I think your right about the motherboard. Welp, gotta get a little bit more modern system. :/

Welp it was nice helping you and losing a fellow member at the same time.
