Portatil Toshiba se "CONGELA" con grafica AMD

Buenos días:
Tengo un portatil Toshiba Satellite P50 B 118
al cual cambié el HDD por un SSD. Luego de instalar Windows veo que solo me reconoce la Tarjeta grafica de Intel pero no la AMD.
Cuando intento instalar los drivers, el portatil se queda congelado y solo se deja apagar a lo bruto.
Al reiniciar el SO falla y ya no arranca.
He pensado en que pudiera ser fallo en las soldaduras del chip grafico y por eso el fallo
¿ Alguna idea?
Desde ya mil gracias por vuestro tiempo
