![]() ![]() One last thought: I see many YouTube videos on "CPU fan spins for a second when power is turned on but then stops immediately." However, what I observe is that the fan doesn't spin when I push the power button, but spins very briefly a couple seconds after I pull the power cord from the power supply. No power light on, no fans spinning, no attempt to boot, etc.Īny help would be greatly appreciated. I am baffled as to why when I press the power button, nothing happens at all. I tested the CPU fan off the board with 12v and the fan spins. I replaced the motherboard with a used one from eBay that I was told tested good (no luck). I replaced the power supply with a new one (no luck). The power strip didn't get damaged, but the computer shut off. When i went to shut down my computer it was already off. Last Saturday we had a lightning strike close to the house. The computer is just over 1 year old so out of warranty.Cooler Master CPU fan # FA08025M12LPA (12v - 0.45A) (4 wires: black, red, yellow, blue).Acbel Poly Tech 180W power supply #PCH023 (Three leads from it: (2) 4-pin 12-volt for SYS_PWR & CPU_PWR and (1) 4-pin for PWRCMD.Business PCs, Workstations and Point of Sale Systems.Printer Wireless, Networking & Internet.DesignJet, Large Format Printers & Digital Press.Printing Errors or Lights & Stuck Print Jobs.Notebook Hardware and Upgrade Questions. ![]()
