Updating radeon 9250 requires admin rights to make changes
If you have an AMD-based computer, and all you want to do is prevent the problem before installing Service Pack 3, then try the new tool I just wrote.It will first check whether you have an AMD-based computer.
Note that if you are downloading the tool on Safari there is a bug in how Safari handles these types of downloads.That is why you end up in the endless rebooting scenario.There are many possible reasons why a computer may crash at boot time.Even though I have tested it as much as I can, I cannot guarantee that it will work for you.By running the tool you agree to hold me harmless for any damage it may cause to your computer.Once I configured the computer to run a disk check at startup it would not even boot into safe mode.
Fortunately, I know Bill Castner, another Microsoft MVP, and he pointed me to a solution.
If you right-click the link and select "Download link as..." Safari will put the name on the containing page on the tool, not the name of the tool itself.
You would need to rename it to something with a extension first to use it.
If not, call Microsoft's technical support line and see if they can't help you.
If you have not yet installed SP3, make sure you disable, or better yet, remove, any anti-malware suite before doing so.
If you do it will check whether the Intel PPM driver is set to load.
