windows 7 - new ISUS - often cursor movements get freezed , inturn ICONS getting resizing +ve/-Ve

- new lop top
- OS : windows 7

I newly purchased the notebook of above atttributes,  very often my mouse move(using fingers) getting freezed. when it is so happens, further mouse movements  causes the desktop Icons  either getting bigger / smaller.

I suspect there may be sort setting needed to behave normally.

Hi Mac
The Icon size change can be done by holding in the "Ctrl" key in and scrolling up or down, either the crtl gets stuck or you are causing it unintentionally. If the key is not fully operational I would suggest returning the notebook to the supplier/retailer for a replacement given that you have the required warranty.

after restarting PC again it is started working. that is why i am suspecting there could be some settng needed to resolve the issue..

please advice
The easiest method to pinpoint this problem would be to use a USB keyboard and mouse, only for a short while and monitor if the problem gets replicated by the USB keyboard and mouse. If it happens with additional devices then it might be setting. if not, my original statement of faulty equipment seem to be more likely to cause it.
