Hello: I do not have a good background in computers and stuff and I am hoping that someone on this forum can help me out on an issue I recently ran into with my SONY VAIO GRZ-610 Laptop. The laptop originaly had a 256 MB RAM module and last year I upgraded the total RAM to 768 MB. The performance was definitely boosted. Recently I started experiencing a very annoying sluggishness. The only thing thats different now is the RAM frequency which has dropped from 1.8 GHz to about 238 MHz. I checked this in the computer properties. I did not install a new software or any kind of hardware and I have no idea what caused this change. Any assistance is appreciated. Thank you.
