I have a preety old laptop(5 years): HP EliteBook 8540w with 2x2GB memory(one rimary slot, one expansion slot). I wanted to upgrade to one piece: "G.SKILL SO-DIMM DDR3 8GB 1600MHz CL10". Each time i run windows 7 prof. with this one it gives me a blue screen with some text and restarts after 2/3 sec. However, when I open the computer diagnostics it shows me correctly 8 GB installed. I also tried different combinations like 8 and 2 GB. I also checed it with 2x4GB from different laptop(parameters were okay), and nothing hapens. I have my BIOS update. Also, when I run the memory test in computers diagnostics it freezes and I have to restart the comp. manualy.
Please help
