Hi all. I have yesterday install windows 7 on my computer, the latest version RTM - 7260 x86. Now i have some problem's with RAM. If i have 1 stick of RAM in computer ( ddr 512 mb) the system works fine. When i insert another stick of RAM (512mb) then windows 7 freeze after about 60 seconds from seeing the desktop. Anybody know what can be a problem? MEMTEST don't recognized any errors.
