I have a Sony Vaio Model VGC RC310G Desktop computer. It came with Windows XP OS and I later upgraded to Windows 7. Everything has been working fine for a couple of years. Recently I noticed the hard drive was starting too make noise and the computer was running slower. I installed a new SATA drive. I ultimately made and image of the old drive onto the new drive.
Since doing this Ii have had issues with thhe mouse movement, ie not moving smoothly across the screen, will not allow me to complete a selection to copy by right clicking, and also having to left click two or three times to be recognized. The keyboard is also intermintent with the keys typed. Sometime you may have to wait for the typing to catch up, or will not type keys you have pressed. The keyboard and mouse are both Logitec and wireless. I have tried other wireless keyboards and mice with the same results.
The sound also stuters when playing as though it is skipping.
Ii also have an issue with getting an Unknown Device on a USB? At times it will just pop on and off. Everything that is plugged in to a USB port seems to be working fine, with the exception of the thinngs mentioned above.
I am using Norton 360 for my antivirus software and have had a subscription with them for 4 or 5 years.
I hope you can help, as I am amost to the point of buying another computer.
