I have downloaded hwmonitor and installed it OK.
In the meantime, a few weeks ago I decided to bite the bullet and re-install windows 7 on the same drive after creating a separate 'compartment' (not the right term) on it. During these weeks I have been using both versions of windows. The new version worked fine for several weeks until a couple of days ago when it crashed in a similar way to the other version, though it happened when trying to print, not when scrolling.
Now I can only run either version in Safe Mode. The fact that this error occurs in both versions does this indicate a hardware issue? I noticed when I re-installed windows 7 that HP do not categorize my laptop as suitable for Windows 7. I noticed some time ago that when I had the screen resolution se so that there was a wide black bar down each side of the screen that it seemed to run for long time without crashing. Sorry, its such a complicated question, but I'm clutching at straws and just about to chuck this laptop about as far as I can thow it. Regards.
