Hello Vin diesel, Welcome to the forum.
First of all, would be great if you could provide some details like:
-Your PC specs
-What OS are you using?
-Plain SH3 or other mods enabled?
-Do you have DVD install or Steam version?
-Do you have the 1.4B patch?
That info would be very helpful, just be patient and other skilled members will give you hand to sort it out. Hang in there...
