My system locked up and on restart it gives the Windows cannot load because the system32 config file is missing or corrupt. I have been through all the windows support for redoing the corrupt registry stuff and it didn't work. So i bit the bullet and did a full reformat...except now i cannot load XP at all it keeps saying the harddrive is corrupt or damaged and cannot be repaired. I take the same harddrive and put it in an old system and XP formats just fine. I have changed drives, video card, swapped memory and everthing I could try to isolate another problem with no luck. Is this possibly a motherboard or CPU gone bad? I have tried to reformat several other hard drives and it gives the harddrive is damaged and cannot be repaired however they all will install fine in the other system. I used different cables and different slots on the motherboard with no change....Guessing I need a new motherboard or CPU?
