I'm running Vista 32bit home prem, have 4Gb memory which shows ok on boot up , but like you state only 3.2Gb in system properties, so 1gig is redundant ? or is there something i need to change for it to show 4Gb ? thx in advance
What are your PC's specs btw? I recommend 64-bit since there's slowly more and more support for it (even some games like FarCry, WoW, Source games) and the most popular software. Just that drivers are still a bit iffy due to lazy manufacturers, and Vista makes it awkward if you aren't running the latest official drivers.
