I downloaded and upgraded the bios for my video card (phoenix guillemot maxi gamer), then loaded directx 7. Now when I scroll up and down in documents, and some programs the writing is temporarily garbled. In my billing program if I type over previous amounts they are garbled until i hit return. In a word pad document I have to scroll real slow, or it's garbled until I click. Is this bios upgrade, downgradeable? Is it just a software upgrade that I can erase? Or is it actually programmed on to the bios chip? The worst thing is I did this to play battlezone 2, and it still did'nt work right. D#mn AMD processor.
