type msconfig in search. Go to the boot section advanced tab. look for max memory. It should be unchecked.

Memtest should not be telling you only 2 gb is testable. Did you build the computer, and how did you insert the RAM as far as slots?

If you open Task Manager, go to performance, resource monitor button, memory tab, how is your memory divided?

Where are you seeing the 4gigs installed and 2 usable? In task manager? can you upload a screenshot of the performance tab in task manager?

If it looks like this (see snip) it is correct.

Is this a 4GB stick? 2GB X 2? 1GB X 4?

Are you able to access and change the slots for the ram or reinstall? Make sure it is seated completely on both ends, especially if you have a board that does not have the lock downs on both ends.

Are you using any video memory set aside for that specific use, or anything else like that?

You attached picture shows you have 2 GB set aside for Hardware Reserved. Maybe something did happen when you ran memtest. How exactly did you run it?

I haven't run it but I notice it allows for a cache to be set aside. Does that number equate to the 2 GB?

Does your bios have a remapping option?

Go in the BIOS and remap the memory.

To the OP

Open device manager and look under Display adapters and see if you have more than one listing there. If you do, then you are sharing memory, most likely, video memory.
