I own an Aspire 8735G Laptop with Windows 7 64 bit. I have had the laptop for barely 3 weeks and the following has started to occur. The menu's within Windows do not allow me to scroll through them. As an example, in the Power Saving window, when I click on the drop down menu to change the amount of time I want my laptop to switch off or dim, the options quickly count down from the point where I click it to 1 minute. It does this everytime. What's worse is that it was only the Power Save Options that did this to start with. But now is spreading to practically any window of options within Windows, not allowing me to change or alter anything. The only way to ensure nothing it does is saved, I cancel the window. This is also affecting the scroll bar on some windows. I cannot scroll to the bottom of a page as it just pings back to the top again. Managed to chat to one guy who suggested that it could be my antivirus that was conflicting. Uninstalled and checked and still had the same problems (tried about 3 antivirus's and none of them were AVG, have heard that's a bit of a nightmare). Thankyou in advance for any help at all.
