PCIIDEX.SYS error

Hello,
I was recently browsing the internet when my computer froze and sat idle before a blue screen appeared and my computer began to reboot and it came to the start up mode screen. I tried to start windows normally but a black screen popped up and said that windows could not boot up becuase the file PCIIDEZ.SYS had either been deleted up corrupted. So now it won't boot up at all not even in Safe Mode or anything I can only go between the boot up menu and the error menu. I have no idea what happened. Some JAVA thing popped up right before it froze and I just did some JAVA update yesterday and it looked ligit. Any help would greatly appreciated. THANX

 

Does anyone have any idea? Anything will help....Thanx
