So much fun flying all that way then lining up for the runway then...CRASH.

 

I was getting tons of different .dll crashes usually about 30min to 1hr or so into a flight. The UI and api were the most common.

 

Figured it was my overclocking so raised the voltage, was better but still crashing pretty reliably.

 

Turns out the solution was to disable my antivirus, in this case MS Security Essentials. And I lowered my voltage back down too.

 

Hope this may help others.

Thanks VeryBumpy for the input. I'm going through this StackHash crash (well, it doesn't crash FSX but shows up when you close FSX). I don't own any anti-virus program (never have, never will) but think you have a very good point about the voltages. Too high or too low CPU voltages based on the overclock will cause crashes and there are many accounts of this throughout the Internet. I recently lowered my CPU voltage to 1.38, from 1.40 and maybe that's too low for my 4.4GHz overclock.

 

Best regards,

Jim
