system interrupt controller help

hi i have recently formated my pc installed my drivers but i get "system interrupt controller" in device manager as not installed could some1 plz help me

 

I suggest you uninstall, and reinstall all your drivers, especially motherboard, and graphics card as it could be any one of them, that has not installed properly.
If your computer is working as it is, you could go to www.driveragent.com
and let them run a scan on your computer (scan is free), it will give you a list of poor, or, missing drivers - i use it regularly, and membership is very cheap, if you care to join at some time , later.
