Hello to everyone i hope someone can help me, This laptop have a discrete graphics the chipset also support the I7 920XM but the laptop starts and fan full speed and i get black screen.

There are people who used I7 740Qm but only worked without turbo because i think lack of support of microcode, can someone add the support for this I7 920XM? i already have a backup and the CH341A should arrive this week. you can remove other microcode because i will use this laptop only with this CPU I7 920XM

Thank you to everyone who can help
