Radeon HD5450

I tryed to update my driver...then my Pc crashed...now my graphic card is like its not working... I uninstall the driver...now i am trying to install it and durin the install its says :The INF file was not found...at the end: Failures occured during installation. Help plz

 

What operating System are you using?
Have you tried going to the Device Manager - Run devmgmt.msc - select the graphics driver, right click properties, select the driver tab then click on Roll Back Driver?
Reboot if successful.
Another thing worth trying if the above doesn't work, is if you have a System Restore point prior to the failed installation. If so, create a new restore point before trying a System Restore.

 

I am using Windows 7 x64....I tryed all u said...but still durin the install : INF file was not found...
ATI Display Driver: Fail
HDMI Audio Driver: Fail

That is AMD's driver download page, enter in your card and the OS you have (XP, Vista, 7, 32 or 64 bit) and download the whole driver package for your card and run the install.
