I have the hp pavilion and the hp psc 750 printer. We installed a cd rw, which started to slowly give me freeze ups at various times and caused numerous restarts. I have since gone back to the original cd rom pending further evaluation of rewritables. Now however my computer says it doesn't detect a printer being hooked up, I've tried deleting and reinstalling but no it’s a no go . Any help or ideas would be greatly appreciated.
