My PC keep on restarting by itself after installing ATI Radeon 9550 driver?

[Adah]

My CPU runs on Win XP Pro SP2. P4 Celeron.512 ram. 2.8 ghz. DVD/RW. ATI Radeon 9550 256mb. 80 gb HDD.Whenever I install the ATI Driver, the pc will restart by itself after sometimes. But once I unistall it, it function normally. Only that, the graphic lagging & overlapping. Already send for repair & the technician said that it's due to incompability which i think impossible. I have plug out the ATI Graphic card & use the internal graphic & still face the same problem when installing the internal graphic driver. Please help..

You might be using the wrong drivers

Remove everything, drivers and CCC software.Then restart computer.plug the VGA or DVI connecter into the ATI card which is attached to your AGP, PCI, or PCI-E. Now the graphics are going to suck becuase theres no drivers.Now disable the onbroad card in the device manager.right click "My computer", manage, device manager and disable the built in video device.Now make sure you have NET2.0 from Microsoft, the CCCsoftware needs that.Then go to the ATI site, not the CD software and install the driver first, then the CCCsoftware.Remember you dont have to install the CCCsoftware, you can run without it, it was bugy for me.

If you have ever had an Nvidia graphics card installed in your machine there could be drivers for the old card still installed. This causes known compatibility issues. There is a driver cleaner available at guru3d.com. You may want to use it to completely remove the non-functioning Ati drivers you've already installed. If the 9550 is the only card you've had in this machine, try reverting to the basic VGA driver in windows. Just go to device manager and uninstall the Ati card, then power down. remove the Ati card.Re-boot. Do Not install any drivers other than the basic VGA drivers from XP.Now get on-line and go to guru3d.com and download the latest drivers for your motherboard chipset and the 9550.Install the motherboard drivers-then re-bootInstall the correct onboard video drivers- then re-bootInstall the 9550 drivers and re-boot yet againIf the motherboard uses an N-Force chipset, you will most likely need to run an Nvidia graphics card. Remember....given the nature of computers, incompatibility is never an impossibility
