I am working on a Gateway 3250S, it would sometimes boot up, but shut down after about 5 mins. Then after that it repeatedly starts and shuts down before the video kicks in. I checked the memory with known working memory, still the same result. I tested the power supply and it was good, but still replaced it with a know good power supply to be sure, same thing.
I disconnected all drives and just booted the board to see if it was a problem with a drive, same result. I added thermal paste to the CPU just incase it was overheating, still nothing. So, I purchased a new motherboard, the same board and at first it ran great, I ran it for 5 hours with no problems. The next day I went to turn it on and back to the same problem. I am leaning toward the CPU as the problem, I did not replace it with the new board. If anyone has any other thoughts I would greatly appreciate it. Thank you !!
