A change such as you have described, along with no similar issues would make memory a suspect. Try the memtest recommended in some of the other threads. Many notebooks do not have Error Correcting Memory (ecc designation) and will not show parity errors. However when memory fails you can get strange errors, not detectable by loading other programs.
