after installing some raid drivers for my computer i tried turning it on and it wont start windows displaying that pci.sys is missing or corrupt.
i looked around on the web for a solution but i dont have a system recovery disc nor do i have a floppy disc drive. i cant seem to get into dos to rollback my settings or anything. has someone got a solution that i could use? i tried clearing for dust. deactivating certain pci slots but i had to leave some open for ram. and it still happened ( pci number 11 and 12) from bios. but my configuration of the settings is mostly guess work atm. and i still cant get it working.
please help!
note: my motherboard is asus A8N-SLI premium and i recently installed nvidia raid controller drivers on it.
also is it possible to get a new hard drive and install windows on it or will it still have problems?
