Replaced the cpu cooling fan assembly and computer starts powering, no video, then shuts down after 2 seconds. What could be the issue at this point? Was brought in for overheating, power issue like this.

Re: Pavilion DV 9005 issue
Please Reviewe all connections care fully. Its Very sensitive issue. If you do not find any open connection. Once again fit the fan with all connections. No display is nothing with Display do not touch that area. See only cooling Fan.

Don't know this exact server. But my guess it is either a heat issue or a power supply issue. Turn it on with the cover off. Check the CPU fan(s). If your CPU is getting too hot the system might be shutting down power to save it. If everything seems cool it might be the power supply I have seen it when the power supply fan goes out on the power supply and the caps inside start to sizzle. Voltage ramps up and fail. Hope this helps. Also, Something that has tripped me in the past. Make sure the power button is not stuck. I had a server that the power button stuck down and it would turn itself off. Took me 2 CPU fans and a power supply to figure that out. LOL
Your pc CPU FAN is not working, you need open it and clean fan,, and under fan, on CPU there is termo cream, don't frgot about it, you need clean it and put new termocream. it is nessasary for cool CPU, that Cpu can not be warm.
If your laptop won't boot up again until it has cooled down, then the problem is a faulty fan and or dust clogging the fan and heatsink fins. The CPU overheats and shuts down (thermal overload) and if this problem is not then eventually the CPU will fail.
Check the fan and if it does not spin freely then it needs replacing.
If the fan and heatsink assembly is clogged with dust, then remove the dust.
you need to check a few things... when the fan/heatsink assembly were replaced, did you make sure that the thermal pads on the CPU and GPU are NEW/Good.... Make sure that the Heatsink GPU pad Firmly sits in the chip....
You can test the thermal controller by using a hair dryer or heat gun.... Point it onto the heatsink pipes and see if your fan spins when the pipes get hot, then remove and see if the fans slow after a minute...
You might have faulty RAM or Misseated RAM... Pull The RAM chips and reseat them...
Also Make Sure Your CPU Is Locked Down....
Periodic Shut Downs Can Be Caused By Quite A Few Different Things...
Typically it's due to Thermal Damage
Though Failing RAM or A Failing Hard Drive, Overheated Video/GPU Chip, Or Even Failing CPU can as Well Cause This Issue...
Check all of these things rule them out 1 by 1 there is no true way for me to 100 percent point out the issue without seeing your computer personally. May I suggest a hat session with us? We can figure out and repair 1000's of issues via chat try it.. This answer is 100 percent free please do rate the best thanks.
I think it might be the motherboard, if its not regulating the voltage properly then to much will go thru the motherboard and the fan won't be able to cool things down properly. Eventually then the motherboard will fail and then no video like your having now.
Try these steps anyway just to be sure:
only hook up the AC Adapter keep the battery disconnected. See if it turns on, if you still get a blinking green light then go ahead and turn the laptop off.
At this point, unseat and reseat the memory one stick at a time in each slot one at a time. Try turning on the laptop after each stick reinsertion.
If that doesn't do it then disconnect the hard drive and the dvd drive from the laptop.
Then try turning on the laptop, if you still can't get video then the motherboard is bad and would need to be replaced.
I would check the bios and see what the shutdown temps are for the cpu as they may be set too low ( check the manuals for the cpu's as you dont want to set it too high as obviously if it does get too hot you dont want the cpu's ( processors ) to blow up or die on you.
Sudden shut downs are often heat related. Modern motherboards have a sensor under the CPU that cuts off the power when the temperature gets above a certain point (sometimes this point can be set in the BIOS). Usually the CPU fan will spin up very fast trying to cool off the processor just before it shuts down. Often you can feel the heatsink being very hot as well.
I suggest you check your vent holes for clogging (hair, dust, etc.) to make sure you are getting good airflow. Next, peek into the CPU fan to see if there is dust accumulated underneath blocking the heatsink from expelling heat (the dust layer acts like a blanket and keeps the heat in). Finally, if you are technically inclined you can try removing the heatsink/CPU fan and reapply thermal paste to the processor.
Hi rebecca_fran, Well the system is shutting down for a reason but before you run off & buy a new CPU fan I want you to try something. Unplug the power cord from the PC. Open your case & ground your self by simply touching any bare metal. (The bottom of the case will do). Please remove the memory currently in your system. If you have never done this before please check within the manual for your eMachine. (There should be a section on how to install memory). You can also click on this uTube link, it’s a bit long but you can skip through the video. http://www.youtube.com/watch?v=SsXNT6fnHmM&feature=related If you have some canned air blow out the memory slots. (Do not place your fingers on the memory contacts at any time). Re-seat the memory, firmly but gently. Leave the case opened & plug in the power cord. Turn on the PC. See if the fan runs & the system doe’s not shut down. If it still does replace the CPU fan. Your PC uses an AMD Athlon 64 X2 4400+ / 2.3 GHz CPU. Here is a replacement AMD CPU fan & assembly. http://www.endpcnoise.com/cgi-bin/e/std/sku=dual_core_cpu_fan.html The CPU will come with thermal tap on its underside. (No need to buy thermal grease). (Make sure you remove the old thermal grease from the top of the CPU). Use a clean rag with a little alcohol on it. (Not dripping). Allow time for drying. Do not scratch the CPU surface.
Hi have you cleaned the heatsink?
Also replace the paste on the CPU, also you could try installing an extra fan on the case to increase air flow.
Also check that your RAM is seated properly and any other chip and card on your board is firmly plugged in.
If all this fails replace your CPU.
