Hello all , My faculty at CHIPTRONIKS told me this :
Get a multimeter with a diode test range.
Connect the meter negative to the MOSFET's source.
Hold the MOSFET by the case or the tab if you wish, it doesn't matter if you touch the metal body but be careful not to touch the leads until you need to. Do NOT allow a MOSFET to come in contact with your clothes, plastic or plastic products, etc. because of the high static voltages it can generate.
First touch the meter positive on to the gate.
Now move the positive meter probe to the drain. You should get a low reading. The MOSFET's gate capacitance has been charged up by the meter and the device is turned on.
With the meter positive still connected to the drain, touch a finger between source and gate (and drain if you wish, it doesn't matter). The gate will be discharged through your finger and the meter reading should go high, indicating a non-conducting device.
No, not usually. Check with your motherboard specifications to see what RAM is needed and the maximum RAM your motherboard can handle.
Check what kind of connections the monitor uses, then compare to the motherboard of your PC, or laptop.

You should not bother to check any power supply in the motherboard. You need to take the motherboard to service centre if faulty.
why?
If your laptop has available RAM slots then you can add it. Also you have to check how much of RAM your laptop can support. It's not more then 2 Gb. You can replace the RAM which you have now by RAM with more capacity. PS Some laptops do not allow to change or upgrade RAM (mostly old models and ASUS Eeee).
It is most likely that there is a problem with your power. If your machine is plugged into mains power, check that the plug socket has power, check that your power adapter is okay, check that the power cable into your laptop is okay.
After the system is up and running you can check the CPU and motherboard temperatures by entering setup?
yes it is possible to use DDR800 on DDR667 motherboard. But to be certain please check you motherboard spec.
The manufacturer didn't include that on the Motherboard CD. If they would included a check utility with a warning then you could get that.
