My fiance's looking to upgrade the RAM in his old Sony Vaio. He'd prefer not to shell out for someone else to do the install, although he's never done any sort of computer self-maintenance like this before. He found the Lexar/Crucial website the other day, which guaranteed system compatibility. Does anyone know if this site's any good? Is he better off figuring out his system's excact RAM specs and buying something in person at Fry's? Should he even be trying to do this himself? If anyone has any insight, I'd appreciate it.
