I have just upgraded my computer with an Asus P4G8X motherboard, P4 2.67Ghz CPU, Tyan G9600Pro Video card & 512Mb memory. I am running XP. When it boots up it passes all Asus POST testing, but when it tries to boot from HDD the power resets. I have tried doing it in safe mode, but still resets. I have stripped the computer to the basics (HDD, CPU, Mem & Video card) but still the same. On boot up screen it also comes up with message "BIOS update data incorrect. CPUID=00000F29".I have retried my HDD in old computer & it boots OK. I am suspecting video card problem, but do not have another one to try. Also, should I download most recent BIOS from Asus & install it. Does anybody have any ideas?
