OK. I bought MSI Mobo i875P neo-FIS2R. Then I bought this Gfx: MSI Ti4800SE-VTD8X. It worked great. Then all of a sudden nothing would show up on the screen anymore. I thought that was strange and I tried my old GFX and then it worked again. Then I tried the new GFX in my old PC, and that worked as well. But when I put the new GFX on the new MOBO, nothing happens. The PC boots fine, but no picture. Any ideas as to what this is? Sune.
