I came home from a 2-day trip and attempted to power up my computer. Out of the blue, I had no video or hard drive activity. When I left it was running fine, and I have never had any problems with the computer of this sort before. It's home built and has been solid from the first day.
I opened up the case, and the symptoms are as follows: Push power button, the Zalman CPU fan LED flickers and then turns off (fan budges a bit) and at that point the row of 6 ASUS motherboard LEDs light up and remain lit (static). There is no beep from the case speaker. All other case fans are running fine. The video card fan is also running fine. I proceeded to remove ALL the cards and memory and unplug all the cables from the motherboard. The system still does the exact same thing, CPU fan flicker, MB lights, no post. I replaced the memory only, tried the other two memory slots, tried it with / without the video card, I get the same thing every time. The power supply fan and LED are both on and seem to be running fine. Everything seems powered except the CPU fan which, as I said, flickers and then turns off.
I don't have replacement parts handy, so I need help pinpointing the probable cause here before I order parts and rebuild. Is it the power supply, the motherboard, the CPU, the CPU fan, ... please help! Thank you in advance for any solutions or further direction.
