Just 2 questions. 1.I have 4 Gb of RAM installed but Vista only recognizes3Gb of it since its the 32-bit version. Is there any way I could upgrade to a64-bit version? 2. I've got ReadyBoost running from a 2Gb flashdrive.Everytime I boot the computer an error nessage appears stating a "disk I/oerror" it says i should replace the disk and hit any key. All I have to do isjust hit a key and it ignores the error, but it is kind of annoying. Anyadvice on how to get ReadyBoost working better?   read more »
