hi, I have just purchased a new PC (Assembled by myself), and i am encountering a problem with reading memory while booting; sometimes when i boot the PC it reads 4GB memory instead of 6GB, when i turn off the pc and try again it works right (read the whole 6GB memory) I don’t know how to fix this. please help, and thanks
p.s.: this always happens when i open the pc when it is cool !!
