GA-P55A-UD4 PROBLEM

[_richard_]

My monitor can't detect any signal, my GPU is running but the fan turns fast.

- Gigabyte GA-P55A-UD4
- nVidea GTX 460 inno3d
- Patriot 3 x 2GB 1600Mhz
- Intel® Core™ i5-650
- Corsair 750W
- Windows 7 Ultimate 64-bit

I tried everything:

I use my GPU on my other computer and it works fine. (no problem with GPU)
I use ATI GPU on my Mobo and it works. (no problem with Mobo)

Hi and welcome to the Gigabyte Forum.

Can you answer a couple of questions first please?

What revision is your motherboard?

What BIOS version are you currently using?

Is this a new build or one that has been running for a while?

Well there is F15 available but it doesn't mention anything about graphics update but then again it often doesn't tell what it does.

You didn't say whether it was a new build or not?

Which slot have you got the GPU installed in?

What colour sockets have you got the memory in?

You should have the memory installed in the white slots  DDR3_1 and DDR3_3

Still the same, I hear 1 long and 2 short beep with SLI but If I use CrossFire It works fine.

You didn't mention that you were runing more than one GPU.
Have you got the cards connected up with a bridge?

No, Im just using one GPU and thats the nvidea, I just borrow my friends ati to test.

You just  said there that you are using more than one card at a time?
You can't use a single card in SLI or Crossfire modes.

I only use 1, If I use my nVidea my monitor wont detect my gpu, but If I change my GPU to ATI it works fine. So I dont get the problm why my nvideo doesnt work.

[Dark Mantis]

I still don't understand where the SLI or Crossfire comes in but I follow the rest of it and are you using the correct output on the back of the GPU?

Which output are you using?

[_richard_]

theres 2x6pin at the back so I put both of the PCI

OK that was my next question actually So you have got all the power plugs in.

Back to my other question what output are you using? How have you connected the monitor?
