Both 737 and 747 crasking my sim. Help?

[Guest Sean Reeder]

I use both the PMDG 737 and 747. Ive been using both for quite awhile and havent had any problems until recently when i did a new FS install. Now both of the aircraft will crash my FS to desktop without even an error message displaying, usually after about 5-10 of loading up the aircraft. Any reason these aircraft are crashing the sim and more importantly is there a way to fix it?

Sean,What do you mean when you say you did an FS reinstall? Did you remove everything (including addons like our planes) and then reinstall or are you saying you installed on top of your old install?

Removed everything. Half of the crashes are straight to desktop while the other half blank out FS entirely making me have to ctrl-alt-delete to close FS.
