Installing XP64 problems...

When i boot from cd and start the installation process shortly after it loads the video drivers and says entering windows setup the screen turns black like its loading the video drivers and then my monitor goes black.. and doesnt come back on. my specs are in the signature, runnin X1800XL with dual core opteron 165.... if anyone has experienced this lemme know id like to work it out and at least try out X86-64bit edition of windows...
