Anyone know why that might be? Do I need to upgrade the BIOS maybe? How does one do that exactly?

The System knows it's got 4 Gig now but says only 3 Gig are useable. I put in two new cards of 2 Gig each to replace what I had before. I had 1.5 Gig of RAM and thought I'd increase it a bit. I just upgraded my Acer Aspire SA90 desktop to Windows 8.1 recently.
