STOP: 0x0000003B in Windows Vista Ultimate 64 bits

[Amadeus]

Does anyone knows about this error. It is something STOP: 0x0000003B. I am getting this error on my screen. I am having a high end gaming system with 8GB RAM and Quad Core processor. I spending quiet a high amount of building the system with Sli graphic setup. But after when everything was done, there was some problem with the system. I am getting a bluescreen and the error code is mentioned above. I am getting this error while using Eudora.

You mentioned that you are using 8GB RAM. So that simply means your system is 64bit. So one thing you need to remember that you cannot use 32bit applications, drivers, etc on it until they are not compatible. I am also having a 64bit system. I had installed a older edition of DirectX which was not compatible with x64 system. This caused frequent bluescreen in the system. So you said that you are getting the error on Eudora. Just check that is not a 32bit version.
