I know how much you all like a quandry, so here's one for you. My laptop, details below...
I've just upgraded to Windows 7 Ultimate, and so far as I can see, should be able to run it hunky dory. I've previously upgraded to 4GB of RAM too, so I can't see the problem. After abour a half hour or so, the lappy overheats and shuts down. No warnings, just 'Thank you and goodnight'. Doesn't do it with Vista or XP, so I'm guessing I'm missing something with Win 7. Could it be a driver I'm missing? BIOS? I'm at a loss. I might cry, come to mention it.
Any help would be very welcome.
