A quad core shouldn't of forced you to wipe your hdd, however it may of forced a reinstall of vista (many of vistas features are in fact processor dependent). You may of caused a static discharge on your motherboard damaging some of the components. Hence why you had to reformat and why your drives are not working. An out of date windows package would not cause this (running a quad on 5 operating systems (xp x86,xp x64, vista ultimate x32, vista ultimate x64 and Linux fedora). The vista is still pre date of sp1 and the blueray drive works perfectly. The only thing I can suggest is trying another dvd/cd/blueray drive and see if the problem still occurs. If it does check the connectors and see if there is any damage to them. Also check the cables. If there are damage to these connectors (burning, missing pins) Then you may need to buy a new motherboard or try and repair it (I advise the first the second option is hard and can be quite tricky. I hope this has been of some help.
