My fiance's laptop used to have a problem where you would log onto it with WinXP Home & it would load everything, but then a few minutes later it would just shut down automatically -- then every time afterwards it would do the same thing. Finally, we took it to repair & had them fix it. I can't remember what they said was wrong with it, but alas it started working fine. Now a few months later, it is starting to do the same thing again. It won't do it immediately like it used to, but you can stay logged onto the laptop for a while (maybe 20-30 mins or so) & then it will just shut down automatically. I thought that maybe it was an issue with the fan not cooling properly, but does anyone else have any other ideas? I hate working on laptops.
