Laptop dell inspiron 3567 recently had a repair of the power IC of the Motherboard. After the repair it worked well but after 4 days it won't power on and I again the same problem arose. Again I sent it to a repairing place and repaired it. This time also Laptop switched ON and worked well. But in the next day morning it won't boot up. But after 2 weeks I just pressed the power Button. It began to work the fan and other components and it displayed DELL support Assist screen. I resetted its BIOS settings to default and it booted up again. That day I switched ON and Shutted down it many times. But in the next day it won't boot up. Once it's indicator light blinked as 2Amber and 1White which means a CPU failure. What would be the problem in this?
