just to make sure go to settings, system, about and it says "64-bit operating system, x64-based processor" correct?

are you sure your RAM is installed good? if windows 10 detects issues with it, it will not use it.

Does your bios show the correct amount of ram?

ok im check on cpuid and i have 2 slot in slot 1 and slot 2 with 4gb but the usable ram is 4??? i check on dxdiag ram is 8 but when i check in my computer properties the usable just 4gb and i have checked on GD hardware anywhere the system checked my Ram is 4gb??

 

[Tradesman1]

Need the model #s of the DRAM as have asked before to get started

 

[fjovian21]

Ok before that i check on resource monitor and go to memory they said the
Available:4903MB
Cached:4950MB
Total:8161MB
Installed:8192MB
Hardware reserved:31MB
in use:3180MB
Modified:3mb
Standby:4860MB
Free:118 MB

Is it correct??
but why GD hardware say my ram just 4gb

its using all your ram based off what you said above.

your computer is using 3.1gb of ram leaving 4.8 free for programs = 8gb . based off your post your computer is fine as they are typical numbers for a computer
