video card hardware interrupt
Hi, I am having this problem. I recently upgraded to a new video card (ATI Radeon HD 4350). I first uninstalled my previous video card drivers, shutdown, Installed the new video card and booted up. Everything seemed fine. I ran a reg cleaner and installed the new drivers. Thats when I noticed that my CPU usage was at 30% during idle. Task manager showed system idle process at 100%. Process explorer is showing hardware interrupt at 30%. I uninstalled the driver and reinstalled with the same problem. I then proceeded to reinstall my previous video card (ATI Radeon x800) only to show that the problem is gone. what can I do to get my new card to work properly?
