No respons at all !

is the new cooler fan does not draw enough power from the terminals that supply the CPU fan. The motherboard is looking for a specific amount of power from the terminal and gives a warning of a failure when the current drawn is different from the specs. You could look at the old cooler to see if the current requirements are marked on it and then match that current with additional fans ETC to the cooler you are wanting to use.

the problem is in your motherboard..this most cause unregulated flow of power from the source electric..but if the green led is off so its the processor.try to test it with a motherboard tester..or get another board that same spec with the you have,and transfer the processsor if it is working

The answer to your first question is yes, your computer is compatible with the MAC OS. However it is very important to continue to ask this question to the MAC Salesperson you deal with when purchasing the software.

The answer to your second question is to do with Heat. Your computer is overheating and is therefore slowing down so it does not fry your CPU. You need to ensure that the Processor Heat sink is making proper contact with the CPU and the fan is connected to the computer main board. Clean the computer of all dust and install as many fans as your computer chassis will allow.
I think this chassis supports up to 80mm fans.

A well cooled computer chassis will work efficiently and effectively.

The Cooler Master Geminii S CPU cooler is a very good CPU cooler for your Processor.
It will reduce the temperature of your Processor by several degrees.

It is very important to get as much, cooler fresh air into your computer chassis as possible. As this will mean that your computer system will run at a far cooler temperature.

If the motherboard used to work with the old cpu and power supply, but does not with the new cpu and power supply, then probably the cpu or power supply is bad.
Why did you change the cpu and power supply?
If the power supply went bad, it could have overloaded the mother board as well as the old cpu.
If you think the old cpu went bad, how do you know it was not actually the motherboard that went bad?
All I can suggest is that you double check all the connections.
If you have USB mouse and keyboard, try a DIN connected pair.
If you are using the onboard graphics, try a PCI express card instead.
Tell us if there is any front light activity from the power switch, drive, etc.?

Before you start read through my published guide as it explains the concept of ESD, it is entitled My Computer is not turning on!!! Is it dead!!! No POST!!! Open the side panel of your computer chassis, there are usually two screws holding it in place. Now remove the RAM and graphics card. Now remove the cables remembering where they all go. Write it down if you have to. Now you should see screws holding the mainboard in place you need to remove these. You may also need to remove the computer power supply to give yourself more room. Holding the CPU cooler and an edge of the board, gently lift it ever so slightly. Just to take the weight off, then move it a bit towards the front of the chassis. Now ensuring that it, is free lift it steadly and gently. Place it on a non conductive surface. Uninstall the CPU if nessary.

All the best and happy computer rebuild/upgrade!
Thanking you

Hello,

you need a new CPU cooler and the part you will be needing is called 'CPU COOLER". Go to any computer accessories shop/store within your vicinity and purchase another CPU cooler. You will need to remove the one from your motherboard and use it as a sample to get another one so that you can get exact size of cooler that will fit your CPU because CPU coolers varies in size and shape.

Good luck.

It seems like there could be a short in the system. Check to make sure that the board is tight in the case, and that no foreign objects are causing the motherboard to short. If there is no obvious problem and the motherboard is new, I would return it as a defect.

Try to reset the CMOS on the motherboard.

Hi alvinkt,

I am using 5450 and it gives me voltage mismatch error and does not boot up, goes straight to BIOS. Is your board revised version with R in the end or pre revision. Could you please help me resolving this error?

as you say,the motherboard or the cpu may be the problem, as you need to connect the 4 pin connector as this is the independent 12v power supply for the cpu and not the ZIF socket like older cpu's. You may be getting power to the board when the cpu is not connected, but when it comes to the cpu taking over because the bios has not been checked, nothing else will run, including drives. If you do not get as far as the bios showing on the screen there is a good chance that the cmos chip is damaged on the board normally either from new or because of the board being stressed from flexing when fitting components to the board which is easily done unless the motherboard is supported by something underneath when attaching parts. If the board is already fitted into the chassis of the pc, remove it and double check that it is not shorting on the chassis of your tower.
