I have a dell dimension 9200 which copy very very slow from internal drives to usb after upgrading the ram from 1GB to 3GB. I have tried changing the rams, installing fresh windows 7, and all I could but the problem seems not be solved. the worse part of it is that as much as it copies slow, it's not continues copying. It copy and then stops then it will continue again and stop repeatedly until the copy ends.
When it starts copying, it starts at 10MB/sec then gradually drops to 3MB/sec. This speed rate gradual reduction happens to only flash drives and micro chips but as for the occasional stopping ithappens even if I'm copying between internal drives but for the internal drives the speed is between 25MB/sec to 51MB/sec. The problem is that it wasn't copying like that before I purchase the 2GB ram. Please any help.
