My work machine is an older (2001) Dell Dimension 4300. P4 1.6ghz 512ram, Intel 845 chipset I got a new monitor, Acer1916Wide and my 16mb ATI Rage 128 Ultra wouldn't support 1440 x 900, so today I bought a Radeon 9550 AGP card. Being in a rush and not paying attention, I tried to install without deleting the old drivers. Then when it wouldn't work I put the old card in and downloaded Driver Cleaner. :knock: Grrr... being stupid again and in a rush to leave work I deleted ATI stuff and I believe a SISVGA? something that I thought was part of the drivers. From that point on I couldn't get into Windows, it looks like it's loading and then the screen goes black. Can't get into safe mode. It wouldn't go back to last working configuration either. Have I removed my standard VGA driver? Is there a way to install it through DOS, or with a bootable floppy? Any help would be greatly appreciated.
