Dell Precision M4800

So sad, I still can't solve it. I broke the 8pin clip and bought it again today. I have flashed your bios, fan spins, power light is on, caplock and numlock are on, but the screen is still black, no dell logo, I have let it run for more than 30 minutes but still the same, when I press the power button it immediately turns off (0.5 seconds). My monitor test with another machine is fine.
Someone please help me in this case !!! Sorry for my english !

Flash both files from post #14

Thanks sir ! but its not working. I have tried all the files in this thread, all with no success. Only change at first boot (bios reset 3 times or 5 times, pressing the power button does not turn off immediately....etc..) but still black screen. I have tried ch341a programm, asprogramer, siberiaprog. My chip w25q40FV. MB LA 9772p rev1.0. Does anyone have any suggestions for me? thank very much !!!
