bios display problem

Hi to all,

I just bought an ECS rx480-a motherboard (supposed new) and a Nvidia
quadro fx1400 (used) graphic card.

When I boot, some displayed characters are mixed up and/or flashing.
E.G, Some letters like a 'D' will be replaced by @, sometimes not. An
'a' will be replaced by a 'q', sometimes not. If I enable the default
booting image, 'presenting the motherboard', some pixels of the image
are flashing. At every boot, the same pixels are flashing. Inside the
bios setup, same problem occurs.

I installed both windows and linux with the nvidia drivers. and the
display is no problem once in the OS. I flashed the bios and it did
not solve the problem. In linux, if I exit the X server and fall back
on the vga display, the problem occurs again. Note that the fx 1400
card has a dvi output interface, not a vga...

I don't have a second graphic card to test the motherboard and as the
display is fine once in the OS, I tend to assume that the problem is
from the motherboard. Am I right?

Should I buy a new 'cheap' graphic card, just to compare the boot
process? I need a little guidance on how to troubleshoot my problem.

Thanks,

Olivier Henley

From my experience, most of the time such symbols are due to faulty
memory for the video card. Your success in Windows however is puzzling.
I would borrow a video card if I did not have one.

The problem was the graphic card. I bought a new one and everything
works fine.

Thanks for your opinion Ken,
