I have an Asus b53j laptop sitting around and i decided to upgrade it. Currently it has an i3 370m processor and i ordered a i7 920xm. When i place it the computer just flashesh the screen and when it is supposed to show bios it restarts and keeps in boot. With old processor it works fine. So i decided the bios does not have microcode for this CPU and i asked for help on bios mods forum. The guy there checked the bios and said that the bios has the microcode for the CPU so i am clueless. Any ideas?
