the cd, dvd and the hard drive aren't being detected
Sound like you might be having a controller or mother board problem. Remove an CD or DVDs that are in the drives, if any. If the above doesn't help. Try going into the BIOS and resetting the BIOS default settings or if it's an older BIOS choose fail-Safe settings.
If BIOS defaults don't help, open the case and temporarily disconnect the CD and DVD drives. Leave only the hard drive connected.Perhaps someone else can offer more suggestions.
The grass may not be greener on the other side but might have less weeds...
