|We frequently have people who started a topic say they have no video, when they actually DO always have video BEFORE Windows loads. The mboard boots - loading a bootable operating system loads Windows - they're two different things. |
You probably had a poor connection in the AGP slot when you weren't getting video from the 9550 card before. With the AC power to the case removed, re-seating the card, or better still, removing the card, wiping off it's contacts with a tissue or soft cloth, re-installing it, is sometimes required
In rare cases there's crap in the AGP slot that is causing the problem that must be blown out of it (don't use a vacuum cleaner).
"....I removed all old catalyst control center and ati drivers. Reinstalled card. Turned on pc and found new hardware installed card and drivers."
Usually you DO NOT have Windows install drivers for a video adapter when Found New Hardware pops up - you're supposed to Cancel that , and install the software using the proper installation program, on the CD or DVD that came with the card, or by using an installation file download you got from the manufacturer's web site.
However in this case XP, at least XP with SP3 updates, probably already has Microsoft supplied drivers / associated software for the Radeom 9600 and 9550 video chipsets (that doesn't include Catalyst) .
Look in Device Manager. If Display adapters shows only one listing for it, if the card has more than one video port and you want to be able to connect more than one computer monitor to it, you probably must install the ATI / AMD suppled software. Microsoft .Net Framework 2.0 must be installed in Windows in order to support the Catalyst software - if that has been installed it's listed in Add or Remove Programs in Control Panel
Or in any case, if you want to use the features of the Catalyst software, you must install the ATI / AMD supplied software.
If the 9550 adapter IS using Microsoft supplied software (see the Driver info for it in Device Manager, if you want to install the ATI / AMD supplied software
- have ATI / AMD download already on the computer
- go to Device Manager - Display adapter - RIGHT click on the 9550's entry, select Un-install
- DO NOT Restart the computer when prompted to do so
- Install the ATI / AMD download - you may get one or more error message, but the installation of the software should complete
- Restart the computer - the ATI / AMD supplied software should work fine, and there will probably be two entries for the card in Device Manager - Display adapters.
