Re: alienware m14x r2 almost dead . 3.3v 5v always problem

ok, i decided to get another m14x r2 faulty mainboard to give it a look. after some work on it now, on this one, i have green light if power on with battery only and red light if i put power supply. in both case it power on and stay with black screen for 70 seconds. then display come on and is fully working. both vga works on windows 10. what can be that 70 seconds before display comes on? bad intel h77 chipset ?


on the other dell, why it wont install nvidia card ? if i boot on dos, nvflasher can see nvidia 650m, but as soon as i install drivers it stop working.


on both pcs i have tried with unlocked bios:

on that second working when i upgraded bios , it stop working and power off just after the 70 seconds.

on the other one it start only if i put integrated graphics only.


any help would be appreciated, but tomorrom in finally going some days on holidays , but still read tht forum these days in the ope of some clue and reply.


edit: attached unlocked bios dump and ec bios dump.

hello friend to i use this bios but there is admin password if anybody know please tell me
