I have designed a display board having RADEON E4690 graphics processor, it is of XMC standard & having x8 PCIe communication link. I have installed ATI Radeon driver for windows XP downloaded from AMD website in my test PC. When I am booting in windows XP ( service pack 3) sometimes the system is hanging & blue screen error is coming (refer to the attached screen shot for the blue screen error). I checked in linux ( Fedora 17) also, there no such problem is coming. I suspect that it may be a driver issue or something related to AMD processor. Kindly assist me to slove this issue.
