Ok. Follow me. 1. Download other OS-es. Mostly choose tiny live systems, and check the mem amount. Reason: We have to close out faulty ram, and OS differences. If the diff is still roughly big, I think with other live systems we can define the missing amount. I suggest tinycore. If you replaced the OS, and the amount is sightly better, then the OS has something that occupy that. So you have to go that way if it's true. 2. Back to BIOS. Check that is the latest on the manufacturer site, If not - you have to do an BIOS upgrade. If you done with this, re-run an complete intensive memtest test 2x witch is best - if you release at night - and if you see errors in any cycle, you have to bring it back your machine - to replace the mem/whole machine. 3. Check BIOS setup. 4. Return here, and tell me the results.
