Just to add my twopenny worth - as Ray says, many people seem to jump to the conclusion that system crashes and blue screens show a hardware problem, but I have always found them to be software related; the 'usual suspects' are landclass files, airport bgls with serious errors and missing scenery bgls (or bgls that 'clash' with other sceneries) in the main scenery/scenery folder.I'm posting this as I just fixed a blue screen crash problem by removing a single bgl file from my setup. Not Canarias (BTW - have they gone for good, their website disappeared; has it reappeared somewhere?), but I always troubleshoot any crash to blue screen problem (thankfully rare) by backing up my scenery.cfg file, then deleting all but the default scenery entries in it; saving that file and restarting FS9 should resolve the problem. You then add entries from the backed up cfg file a dozen or so at a time until the problem returns. After a while, you can find the exact scenery, and then the exact bgl file (usually just one), which is responsible. Removing it should then solve the crashes. As I say, it's worked 100% of the time for me.Well, you probably all knew that anyway! Hardly devastatingly original, but I do think lots of people immediately blame their hardware in these cases. Could be an expensive false assumption!!M. :-)

Hi Martin,A very logical solution if somewhat time consuming. I admire your dedication. Fortunately I haven't had any blue screen crashes so I count myself lucky rather than skillful.I run ScanAFD irregularly but don't remember having any problems with the Canary Islands scenery. I thought their offering was pure ground terrain without any airport enhancements. I have the Aerosoft Canary Islands package and haven't encountered any such problems.Cheers,
