When i turn this laptop on power led lights up,fan turns slowly,dvd drive lights
up after that laptop turns off. After that it turns on again on its on and repeats
same steps.There is blank screen,does not get to dell logo,F2-F12 does not work. After repeating few times three led lights up indicating error code cpu
failure.
I have swapped working cpu with same result.
I have put in new ram with same result.
When i start laptop with key "d" pressed the screen goes thro all diferent colors
then switches off.
I have removed rtc battery overnight and put it back in the morning, turn laptop on and it goes thro all above steps but this time there are NO error led
for cpu failure showing any more. The laptop charges battery ok.
The laptop has i7 quadcore with NVIDIA gpu.
Motherboard is Qala1 LA-7762P.
Is it power issue, gpu faulty or bios issue?
Can anybody help me sort this problem please.
