My wife complains of her Laptop with Vista "crashing" now and then when she is in the middle of something e.g. writing an e-mail on Gmail. The laptop appears to swicth off she says, in so far as the "on" button has no light around it. When she presses it and reboots, the computer restores her to where she was . . .e.g. in the middle of writing that e-mail, via the "Windows was ot shut down properly" message. I've not witnessed what happens myself so am only going of what she tells me. Any ideas? This has only been happening since she allowed updates to Vista. She wouldn't be able to tell me which since she is computer "illiterate," by her own admission.
