What is Memory Controller in Motherboard

[waris007]

Recently my pc become dead. After i visited service center they told be that the memory controller and GPU got damaged. They said gpu is not serviceable but memory controller can be replaced for about 7$ but after the service my pc worked but i checked every point of MOBO i couldn't find any new part. They cheated me or i missed to find the part.
How this memory controller looks?
And one more thing, is gpu can be serviced and my fan is running.
Please Reply
Thanks

What mobo? If it's an older one like a socket 775 the memory controller is part of a chip on the mobo (the NB chipset) - if it's a newer mobo 1156, 1366, 1155, 1150, 1151, 2001 then there is no MC (memory controller) on the mobo it's in the CPU. Was there a labor charge?

My socket is LGA 775( Core 2 Duo)

Believe on your mobo, it sits under a large heatsink (copper maybe?) that it to the left of the CPU socket as you look at the board flat from the front, if in a tower it's sort of below the CPU socket

If fairly new may be under warranty, otherwise might find a shop that can fix it, though that may well cost more than it's worth, depending on what GPU you have
