Maybe hardware trouble : too high temperature processor are the main cause of failure. What you can do : If you are familiar with computer material (and only if), turn off power of PC, open your PC, remove your CPU Fan with a screw driver (particularly delicate part, beware !!!). See if there is a polysynthetic thermal compound between the cooler and the cpu (look like chewing gum). IF there is no material here, stop your PC. Try to find high thermal conductivity thermal compound (with silver or copper) : only cost 2 euros/dollars approximately (You can also buy a new cooler, which has thermal compound with it, easier to find). Place a small quantity of this material between the CPU and the cooler. Replace cooler (not easy), close your computer, turn on power. If you are afraid of that, you could bring your PC to a specialized store which will do that for you. Not expensive... Lot of the "computer freezing with Vue d'Esprit" problems, and only with Vue, are due to this hot CPU: long calculations are heating the CPU causing errors. The other soft which required shorter calculations are not causing these errors. But even the blue screen (or black screen) problems without any reason (random reboot) can be due to that problem. Better to turn off PC before CPU failure. On some motherboard, there is a possibility to watch on CPU temperature, going inside the Bios. See if the temperature is below the normal (which depends of CPU type). You can find these normal operating temperatures on the web. I had exactly the same prob with win2K which was due to excessive temperatures. Hope it helps, Yves
