Hello folks. I've searched the forum but can't find anything pertinent to my particular problem. I've been flying online with MSFS since forever with no problem but now I have one. For the last few days, within 30seconds to 30minutes of connecting to VATSIM I get the dreaded BSOD. Driver_IRQL_ 0x000000d1. No filename is delineated. I've changed nothing in either hardware or software. Nothing else is affected. I can go online with the Internet, MS Outlook etc. I can fly MSFS offline till the cows come home. It only happens when I connect it to VATSIM. Any suggestions would be most welcome as I really don't know where to start looking.
