The ATI page for Mobility Radeon 7500 refers to Dell only.
When we install driver from Dell, it bluescreens and restarts possibly when timed out for sleep. We had updated driver in first place to get Sleep since Win7 stock driver won't sleep.
However, I had originallly only installed it in XP SP3 compatibility mode, so now have reinstalled it in XP SP2 mode (the only viable XP compat mode I've found previously) so maybe that will fix it? We'll have to see.
Thanks. Any other ideas are much appreciated.
