I have processor XP2200+ running in MB GA-7VT600 1394 without problem for 1 year. But then PC once froze and since that time I cannot run WIN XP on this computer. I replaced step by step all components (MB, HD, graphic, memory, power source, monitor..) Only CPU remains the same. I've formatted HD and start new WinXP installation, but it freezes at the time when Windows is starting. I did run lot of HW tests - no problem indicated. I tried Linux Slax installation, or run from memory - no success. But DOS is running without problem (I used it for HW tests). I installed Win 98SE - it is running as well without significant problems, but Win XP cannot be installed or Win 98 upgraded - it fails always. (I tried both FAT and NTFS filr system). Unfortunately I do not have alternative CPU to test it. Is there anybody who can explain what can be wrong?
