Moire info needed.
Make/model of system board/computer.
What does your BIOS show? At first glance it appears you have shared memory, typically this is a laptop setup and if memory allocated to video less available to the system.
Hi aiduIE and welcome to Ten Forums. As RWone said we need more info. For start, take a snapshot of your memory info in Task View. Like this.
This could be because of unsupported memory or misconfiguration.
Google found this: (it is for Windows 7, but should be the same)
INSTRUCTIONS
1. Check your system properties
(If it says "x.xx usable")
2. Click on the start button, search "msconfig" and press enter.
3. Go to the boot tab and click advanced options
4. UNTICK the "Maximum memory" box
5. Click ok, on the small dialog box
6. Click apply and OK in the big dialog box.
7. Restart and check your system properties.
Thanks a lot AndreTen! I just did the steps and it now says 15.8GB usable. Appreciate it
