My old computer's motherboard died on me and so I replaced the whole computer with a new Dell 620. It comes with an Intel i3 processor, 4 gigs of memory, a 500 gig hard drive and Windows 7-64 bit. Not a bad computer for $399. I was able to plug in my old hard drive and retrive most of my old files so I didn't lose anything. This new computer is running perfect !! I don't want to mess it up by installing Windows 8 on it, nor do I want to do a fresh install. It's working great now, and I don't want to monkey it up. All my music recording programs seem to be working fine with the Windows 7-64 bit.
