When turning on my pc with vga output connected to monitor, the i see post, can go to bios, etc, but when i boot up pc with DVI output used, the no picture, just after to log on to windows, but then no problem with it, 3d, desktop, etc working.

I have similar problems with my Firegl X2 and my two X850 XTs (only one of the video connectors works during post). It's kind of surprising that I never see this mentioned anywhere on reviews that were done at the time.

Try to reflash it into reference 9800XT.

I must be some kind of standard: the anonymous gangbanger of the 21st century.

When I have had that kind of problem, I have usually assumed it is problem with 70Hz text mode that is used before changed to 60Hz when windows boots. I assume you must be using LCD monitor because I never had that kind of problem with a CRT. Easiest way to find out if it is the same problem if you could try a CRT monitor with it. You could also try another LCD monitor. The thing that made the problem strange when I encountered it was that 70Hz mode worked with another video card, so it must have been result of combination of specific video card and specific monitor when it happened to me.
