driver version? Is this a known working (artifacting) card?
I tryed the ati 4800 drivers...well it boots to bios with artifacting...so does that mean it's working?
Getting into the BIOS doesn't necessarily mean "working". I was meaning, (aside from artifacts) was it working whenever you removed it to install your new card?
On that note, what is your primary card? If nVidia, run driver sweeper in safe mode and remove all traces of graphics driver software.
I have 5870 running...then poped in 4850, booted to win7, it reinstalled drivers for it, restarted, bsod..took out and poped back my 5870 and it works just fine...is that what your talking about?
