Last week I downloaded and installed a copy of windows seven ultimate after reading that it was legal to do so because certain parts of the program had been removed. I know, stupid. I ran it for three days and figured it was not worth the risk so I wiped both drives and reinstalled xp which I know is legal cause I bought it. Problem is now my optical drives are not working. dvd-rw and a cdr. What I really cant understand is they work perfect till I start down loading updates and installing service packs. I replaced hard drives last month and reinstalled xp and everything worked fine. So, What could of happened putting windows 7 on here that would make my optical drives fail. Thanks for any help.
