What happens is that some of the addressable memory (regardless of how much you have physically installed) is reserved for use by page files or by some of the devices that you are using, such as a graphics card, PCI card, integrated network connections, etc., so it's unavailable for use as normal main memory. Hope that helps.

Try resetting the mobo to best defaults, if that doesn't help try resetting the CMOS

Thank you but I already done this with no difference. Any other ideas?

Have you removed the drivers for the card reader and running a registry cleaner like Wise?
