Well, I'm not sure the card is at fault - go to ATI's site and get the latest drivers for your card first. Then, uninstall any ATI drivers/software you currently have installed, and reboot. Last, install the new ATI software and drivers you downloaded, and see if that helps. i have tried that mostly of all the drivers possible for this card its its kinda outdated u can say radeon 9250 and my mobo is ASRock 4 core dual SATA2 link and as for as the voltage idk i cant check CPU-Z or anything now im running in safe mode if it was undervolting wouldnt i still get this error in safe mode? everything seems to run fine in safe mode for some reason minus all the problems as my monitor randomly cutting off and random display problems and restarts. How can i check in realtime for this? im actually waiting on this new card now off that vga supported list..it should be here anytime now today so i can actually check if its my card plus to be on the safe supported side
