yeah when i directly turn off in middle of giga byte screen again and again the after sometime it shows that error and a window opens and load last known good configuration

Well from what you describe this would be normal in so much as you are turning the system off without shutting it down properly and this corrupts the data. I know you don't have a choice  but that is what is happening.
Please just make a detailed list of all your hardware that you have in your case including your PSU.

OK that's good. I need the exact moel number for the memory. If it was a kit then the kit number please. Did you check the QVL of either Gigabyte or Kingston to make sure it was compatible?

[mspunk166]

what  you mean by QVL i didn't get it?

[mspunk166]

mamory means RAM ?

[mspunk166]

product code of RAM=KINRAM1108
Name of commodity=KIN DDR3/1333/2GB_  KVR1333D3N9/2G-SP

I GOT THESE TWO MEMORY STIKS IN DIFFRENT COVERS

QVL is a list made by manufacturers so you can see what memory is compatible with what board. They dont all work together! It stands for Qualified Vendors List. You need to have a look on Gigabyte's QVL for your motherboard and see if it list's the memory you have got. You can also check on Kingston's website for the memory and see if the motherboatrd is listed against it.

Memory does mean RAM, yes.

Mamory is something totally different by the way

I have just checked your memory and although it is compatible with your motherboard you bought it as two seperate modules not a matching trio which they should have been. You should be running 3 modules on this board at one time. It is a triple channel board although it will physicall accept dual channel you will need two matching sticks and you will lose a lot of perfomance by doing so.

[mspunk166]

it means i have to buy 2 gb memory for this?

[Dark Mantis]

Are you using 32 bit or 64 bit Windows?

[mspunk166]

i m using 64 bit windows 7

[Dark Mantis]

In that case I would advise you to get 3x2GB modules as a matching kit. Trying to use what you have there is not working at all as they aren't even matched. You could buy a matched poair but that wouldn't be doing justice to your hardware or the Windows 64 bit OS. Make sure that you get modules that are compatible with your motherboard and a matched kit or you will just be wasting more money.

I am still not sure that your PSU is big enough either but one problem at a time.

[mspunk166]

ok but what should i do?
buy 2 GB same memory module (same model )    and these stiks are also compatible or u r saying to buy new 3*2GB memory stiks
then i have 3 memory modules......you meant this?

[Dark Mantis]

Yes you need to purchase three new sticks together in one package as a matching kit. Three sticks if the same type won't do. They have to be a matching kit.
