I have recently used Partion Magic to partition my hard drive from 15G/45G to 25G/35G. Now I get a black screen with 'operating system not found'.
When i turn laptop upside down???????, I am able to turn computer on for 5-10 minutes then I get a blue screen Displaying "Beginning Dumping of physical memory".
I have downloaded memtest86 v3.1 to check my RAM but no errors.
