Since I had my computer to the shop (for virus removal - they couldn't remove whatever I had and had to reformat the HD) my mouse cursor is moving in a jerky fashion when an Internet page is loading or has a lot of animations on it. It isn't this way all the time, for instance on Google.com it moves normally, but pages like TCM.com, it's really erratic. At the shop they had a optical mouse plugged in, but at home I have an old-fashioned rollerball mouse which is fairly new and plugged into the PS2 port with an adapter (it won't work in the USB port). I looked in the device manager, but there were no hardware conflicts and it indicated the device was working properly. Also, before taking it to the shop, I had Firefox 3.6.17 installed, but they installed Firefox 7.0.1. Any ideas why the mouse cursor is intermittently jerky and what could be done to remedy this? Thanks in advance.
My system - HP Pavilion 750n, 1.6 GHz Pentium 4 processor, 768 MB RAM.
