Displays momentarily and asks for CPU fan connection. I have changed 4 fans and still get the same error message and the display goes off.


You're sure you have the cpu fan connected to the correct socket? sounds like it's not connected, or is connected to a different socket. Does the fan turn?

My computer keeps shutting down after a few minutes. I have replaced the powersupply as well as the cpu fan. I am being told now that it is the system/motherboard. Is that an accurate answer?


When the CPUoverheats it goes into thermal shutdown and will not boot up again until theCPU has cooled down.
The heat sink may be clogged with dust, which causes the CPU to overheat byreducing air circulation through the heat sink.When you replaced the CPU fan, did you put new thermal heatsink paste on the CPU/heatsink? If not then the CPU can overhest. Your computer fanmay be faulty and not spinning freely, in this case replace the fan.
Check the fan and heat sink assembly and remove the dust, loosen the dust anduse a can of compressed air to clear away the dust.

Pentium D problem


Hi oilian,
Be glad it did shut down. If it didn't, your new CPU could haveover heated. There are a few reasons for a CPU to over heat.
1.) There is no thermal grease or too little on the heat-sink assembly.
2.) The old thermal grease was not removed or the old thermal tape was not removed.
3.) The heat-sink assembly was not cleaned completely with alcohol before applying new thermal grease.
4.) The CPU fan is running too slowly.
5.) The heat-sink fins are possibly filled with dust build-up & the CPU fan can not cool the heat-sink assembly. Boot to the bios & go to Hardware Monitor. There you can check voltage, CPU fan speed, CPU temp & other bios monitored settings.

Good luck oilian!

Pci express slot


Hi dineshcs.
When adding a new graphics card (Your's being a PCI-Express), you must change a bios setting under the title " Advanced " section. Open you're M2N-MX manual & turn to page 2-21. You need to change the boot order for you're graphics to list,
[PEG/PCI]. Change Initiate Graphic Mode Select to [Disable].
These changes stop the onboard graphics card from loading & allow the PCI-Express card to load. The issue of possible motherboard overheating can be caused by many things. Here is a list of things to check.
1). Check the CPU heat-sink fan. Make sure the fan blades are
free from dust build up. Check fan speed in bios (Its RPM will be listed). It should be running a min of 2300 RPM.
2). Also in the bios is Hardware monitor. By booting into the bios go to this & watch the temp of CPU & motherboard. If either is getting too hot suggest you add a side case 3" fan to the system to help lower the CPU & motherboard temp.

Good Luck!

Processor over heating


Hello,

This is normal behavior. Fans normally only run when they are needed, and your computer has multiple temperature sensors that direct this behavior (they are primarily located on the CPU, which could explain why the fans all worked when you took the CPU out). You should only be concerned about the fans stopping if your computer is, indeed, overheating.

Your CPU may have a problem


Have you removed all memory, other cards and unhooked all other drives to see if a short exists there? With a 300W PS some other component may be pulling too much that the CPU can't start so it tells you the problem is with the CPU or The CPU its refering to is on the video card? Good Luck, Tim
