My system operations (Windows 7 Ultimate), was working perfectly with 1x2G (RAM DDR2) by months, but I bought new 4GB (2x2GB RAM DDR2) by kingston.

Retired my old memory 2gb and install the new 2x2gb on slot 3 and 4 of my motherboard (ECS A780GM-A).

The user manual of motherboard speak about the best performance of memory should installed on slot 3 and 4.

The problem: After 2 hours use more or less. My system crash (death blue screen). Before the new memory, it never happened.

Can anybody help me?

Run memtest overnight. –  ta.speot.is Feb 13 '12 at 10:29

1 Answer 1

With the first crash on th 9th clearly happening from a memory error, and the other two unhandled exceptions in drivers - and based on this happening with the addition of the memory, it seems strong that one (or both) of the two new memory sticks is bad. Your bios should have a boot time option to do extended memory diagnostics. Let that run over night. If it generates any error logs, request a replacement from the manufactor.
