Strange laptop lock-up problem
I've got a problem with several Toshiba Satellite laptops.
They have Pentium Dual Core CPUs, 1GB RAM, running XP Pro, although they came with Vista Basic.
The problem is that occassionally lock-up, seemingly for no reason. I can't establish a cause for it, it seems random. When they lock up, Windows appears still to be working (turning off Wireless prompts a moan about no network, pressing Power once shuts down) but the keyboard and mouse don't respond to anything!
Any ideas - my teachers are beginning to revolt! :)
