I have a computer with AMD Phenom 9600. It has Vista operating system. I have problems with speed and with some apps. Is it likely that the problems are due to the procesor or the OS?
While it COULD be your processor is simply not powerful enough for what you do, and being lighting fast is not what most people think of when you are talking about Vista, these are more likely your culprits.
Spyware
Adware
Disk too full
Lots of temp files and internet cache you don't need.
Badly defragmented hard disk.
Not enough system memory.
To many programs running in the background.
Older device drivers that may have new faster revisions.
And lastly, you may just be getting used it to your rig. Even though it technically is just as fast now as when you first got it, we tend to get "used" to our PC's over time, and they just seem slower as they get older.
