gracias man, ya casi sale, lei el primer link y encontre esto:
0xC0000218: UNKNOWN_HARD_ERROR
(Click to consult the online MSDN article.)
A necessary Registry hive file couldn’t be loaded. The file may be corrupt or missing (requiring either an Emergency Repair Disk or a Windows reinstallation). The Registry files may have been corrupted because of hard disk corruption or some other hardware problem. A driver may have corrupted the Registry data while loading into memory, or the memory where the Registry is loading may have a parity error (turn off the external cache and check the physical RAM).
ocupa mas RAM?
o mira, tengo un CD del Home edition y uno del XP PRO y lei este manual:
