I am trying to replace my old ATI Radeon 9200 128MB for a GeForce 7300 GT 512MB DDR2. In the instructions says that i have to uninstall the controllers of the ATI Radeon 9200 128MB but i don’t know what to uninstall. What i did is i went to “control panel” then to “add or remove programs” and remove the things that say “ATI software Uninstall Utility”, “ATI control panel”,and “ATI Display Driver”. Then i turned off my computer an took off the video card and installed the GeForce 7300 GT 512MB DDR2, but when i turned on my computer my CPU did turned on but the monitor stayed off and nothing appears. So if somebody please could help me you all are welcome. I have a Intel Pentium 4 processor 3.20GHz1 with hyper-threading Technology, Microsoft Windows XP Home Edition and 512MB PC-3200 400MHz DDR. 530G Hard drive.
