I have Windows 7 home premium 64 bit on a 6month old pc with 1TB hard drive petitioned into 2. The mouse and keyboard are wireless.
Every now and then, the mouse does not respond correctly, it seems to be slow and be very jerky, making it hard to position accurately. This usually responds to periods when I think (judging by noise) the the disk seems to be working really hard. When the noise stops, mouse performance returns to normal. There does not seem to be any correlation with what program I am running and when this disk thrashing takes off.
It seems from other posts that the disk may be working because indexing is going on. Is this likely to effect mouse performance? Is there any reason not to turn indexing off if this is causing the problem? Can I set indexing to be done on demand, say at the end of the day?
