I ended up in setup and found my video card there: nVidia Riva TN2 Model 64.
I use the TNT2 Model 64 which works perfectly in DSL in a Gigabyte GA-6VXE7+ 'VIA Apollo Pro Family AGPset' motherboard, so, if the Red Hat 6.2 shows no failure there, the video card itself should not be the problem.Thanks,
I am going to give DSL-N another try assuming that the bad RAM was the cause.
