System:AMD 2800 XPWindows XP SP11Gig RamNvidia 6600GT w/fan2 Case FansDial up InternetMSFS9/PMDG737NGHello allCame back to the PC after it hadnt been used for FS in several days and the system, when booting Windows, crashed two times. Performed System Restore and all seemed good 'till last night and tonight, all of a sudden after flying for 2-10 minutes (has happened twice now) FS9 crashes (while running NetZero, ugghhh) and I HAD been using another ISP and this didnt happen, but then again the whole pc crashed on startup before ever starting FS or Netzero. Then tonight, no ISP running, FS crashed the whole PC. Went to black and restarted itself. "Windows has recovered from a serious problem". I look at the error report, it mentions a minidump. Any clues?Dont think it's Netzero related (yet, but it does load crap on here)thanks,Eric

A system doing a warm boot from within an application (especially a game) often means overheating. The easiest way to rule that out is to remove the left side case cover and stick a fan blowing cool air into the open case. Then go fly. If the problem persists then you can continue the search for the problem (I'd be looking at the memory as the culprit). If the system works with all the extra cool air you should first give the case a good blowing over (that canned air works pretty well) and also consider adding more (and bigger) fans to your case.Good luck,Greg
