IDE connection not detected

Hi folks,

GOOD DAY!

I know someone could help me solve out my problem. I have a mobo with 4 sata connection and 1 IDE.. i am using 1 SATA connected to my HDD and i have a CD/DVD rom connected to the IDE.. in the fast few days CD/DVD connection works well, but few days later when i boot it up the CD/DVD was not already detected by my mobo only the SATA… even if trying to use other devices the still IDE connection r not detected…

I already try an option, I go to the registry and deleted the whole thing like the upperfilters but 1 thing when i go through that access theres no lower filter on it… and there i deleted all of it!!

I dont know what to do hope someone could help me out!

Thanks
