I'm running a laptop with an AMD turion ML-40 and an Nvidia 7500GS go 512MB, 2 MB ram and dual hard drives. I recently upgraded from Vista to Win 7 and noticed applications and games that were fairly stable were not running as smoothly as they previously had.
I was playing around with different hardware settings when I noticed something I consider very strange. I checked out the windows experience index and under vista it was 4.2. The lowest score was for the hard drive at 4.2. The processor was running at 4.6. Now under windows 7 the experience index has dropped to 3.6 and now the lowest score is the processor. Has anyone experienced something like this where the processor just drops in its performance index? The only thing I can imagine is the machine was overclocked originally and by installing Win 7 I reset the overclocking. However I thought overclocking was controlled in the bios and not the OS, so I don't think that is the issue. Any suggestions on how I can get the processor performance back to where it was, or why it dropped in the first place?
