You have to have a 64Bit processor to run 64Bit. As far as I know, the main difference between the two is usable memory. 32Bit is a maximum 4 gigs of Ram whereas 64Bit can be up to (and from what I have read) beyond 128 gigs. 4 gigs is usually plenty for most folks. This vista pc came with the option to run 32 or 64Bit. That is because a 64Bit CPU (this one) can run a 32Bit or 64Bit system. A 32Bit CPU (processor) can't run the 64bit system though. Any of this make sense? LOL

Dual core means basically 2 processors. Not 2 Physical processors but capable of operating with the processing power of 2. Not really related to 64bit. It's a processor thing. A Quad core would have the processing power of 4 individual processors. 64 bits is faster the processor can process 64bits at a time vs 32 bits. It can be more secure operating system. A 64 bit System can utilize more ram. Just a bit off the top of my head you could Google 64 bit vs 32bit and find much more information. You could assume the hardware supports it.....

I did try a music CD as well and nothing happened. Couldn't see a directory or play it. Today I put a clean CD in; a format menu box popped up; did that. Then dragged some folders to it (using Windows Explorer option). They copied. Popped out the CD and put in the old "unreadable" one and the burn menu showed again but this time with additional option to view contents, lo, there were all the folders. Why windows explorer couldn't read it before? Now the problem is trying to open a .jpg to view. When I click on one (I use IrfanView) all the filenames turn pale and the CD spins, and spins, and spins. The cursor remains as an hourglass. When I try to close the explorer window a message saying program not responding shows up and I choose end process to get the explorer window to close. I'm wondering if the old Roxio program I used to burn the CDs is the problem. Don't have Roxio on this computer.

"Both versions of Internet Explorer are included to increase compatibility with existing programs and Web sites. The 32-bit version of Internet Explorer can host only native 32-bit ActiveX controls and other 32-bit Web page objects. The 64-bit version of Internet Explorer can host only native 64-bit ActiveX controls and other 64-bit Web page objects." "If you experience problems when you use the 64-bit version of Internet Explorer, try to view the same Web site by using the 32-bit version of Internet Explorer. If the problem occurs in both versions of Internet Explorer, you must determine whether the problem is caused by a Web object or if the problem is caused by Internet Explorer."
