UPDATES: I fixed the problem, discovered some low quality silver conductive thermal grease under the CPU cooler causing shorts between the filtering SMD capacitors, did a deep clean and flashed the bios previously recommended by PESTE post #29 and that's it worked fine worked again, later formatted with windows and returned. Thank you very much for the availability of the forum technicians! -
Thank you for your answer!
I flashed the bios released in post 29 but the problem changed, at the first startup the LED remained lit with the black screen then after 5-6 seconds it went off, at the next startup it was the same, 5-6 seconds then it went off, at on the third restart the LED remains lit but the screen is black, the fan starts turning normally again as soon as the CPU warms up....Leave a comment:
