Because this is my fist post to this site i would like to than everybody who has help me through there Questions. But it seems i have a problem no one else has ever had becaus i cant find any informaton neither on this site or in other Forums.

Situation: 3 weeks ago i downloaded a plan from this site the f14 tomcat 3.0. The Pack includes a Gauges Addon named COP3. It is used for the landing and taking off on aircraftcarriers and also simulats breaking the speed of sound. I installed the pack and everything worked fin. I also used the COP3 Addon for ohter Jets and had no problems    Until....

Problem: A friend of mine gave me an different Grafikcard. After installation and many Overclocking tries i had to realise the card was not much better then the one I already have (Overclocking tool Ntune) I did not run FSX with the new card. Disapointed i reinstalld my previos ati card and wanted to play FSX. Game started fin, I picked a Jet chose my seenery and hit Start Flight. Well as you can gues the flight did not start and my pc rebooted atomaticly. After reboot I had the Error message :

BCCode : 19     BCP1 : 00000020     BCP2 : E25CB3C8     BCP3 : E25CB4A0    
BCP4 : 0C1B0801     OSVer : 5_1_2600     SP : 2_0     Product : 256_1

I did a little research and i found erverithing from Memtime problem to your BIOS is damaged or changed. After a lot of playing around i found out that the COP3 Addon was causing the problem (cant say which part of the applicaton because i got tierd). Every thing else in FSX runs fine also all the Jets as long as the COP3 Addon is not installed. All other Programms and Games run fine to.

My Fixing Attemts: I deinstalled FSX with all my addon airplans and cleand up the regestrie. Reinstalled everthing from scrach installed one plan with the Addon and gues what ... It rebooted again

I cant understand why it worked before i installed the other card. I know that Ntune sets all possible Mainboard clocks but i also asumed i would restore them to default after deinstallation  . I my self em almost convinced its the BIOS but i often make simple mistakes and hop i am overseeing something. I also made sure i have the newes version of c++ and made sure all other needed Addons such as fsuipc were installed and running

If anybody has any idear i would be greatful
