I still haven't figured out what's up with my computer. I tried updating all my drivers, including my chipset driver. I tried using different refresh rates, I tried running Creator 2009 in Windows 2000 compatibility mode. Nothing worked. To try to figure out what was going on, I took my software to work and loaded it on my OptiPlex 620 with an Intel 82549G Express Chipset. When I compare my computer configuration at work with the one at home, the only significant difference was the processor and chipset. The computer at work had a slightly faster processor and a different chipset. Everything else was practically the same: memory, display settings, refresh rate, direct x 9 version, support pack version, etc.
Yet, the screen did not go black when I started Roxio at work. Loading Media Manager still resulted in a rapid flash of the load screen, but the flashing was not as prolonged and the program loaded much faster. Any suggestions?
