Typically people mention the brand of PC and the operating system, which makes the problem appear to be completely random and therefore beyond rational solution. This problem comes up quite often on the net, usually on PCs but sometimes on Macs, but almost never with any useful information. Although I am reasonably PC literate, that process is beyond me. I have read that the only cure is to "re-image" the PC. I have tried to get help from Dell without success, and I have also sought advice from my IT manager at work but again without success.

When typing, the cursor randomly repositions itself in previously entered text and I only become aware of its changed position when I look up to review what I have typed - usually gobbledegook. I have a Dell Studio 1555 laptop which has developed an infuriating habit.
