que tipo de error es ese?

0021 This can be caused by two completely different things either:
A. DVD Drive Time out - Can be caused by problems with a firmware flash. This is also speculated to sometime be caused by a problem with the southbridge chipset on the motherboard based on how it connects to the DVD drive.
B. GPU error, generally caused by a poor connection to the mainboard (cold solder joints/bridged solder joints) See error 102 for more information
hay dos opciones pero seguramente sera la B un error por las soldaduras de la GPU
0102 GPU Error, this is usually caused by a cold solder joint between the GPU and the mainboard
