Thought this would help alot of people out. My 3-yr old ASUS AIO Z240IE stopped booting. The power and HD led lights would blink every 5s and the fan would also cycle at same frequency. Turns out it was a clogged fan intake and the computer was going into safety mode. Just needed a good cleaning and BIOS reset.
You’ll need to remove the motherboard to get to the dirty fan intake. You will also need to remove the CMOS battery for the reset. Be careful with the cables. An extra hand and a pair of magnifying goggles will ensure a good reassembly. I previously threw out (2) AIOs in the past 10yrs before I discovered the clogged fan. They probably had the same issue.
