It is strange that your brother has the same problem.
Has this always been the case, or is this a new problem?
One thing to try is to reinstall the motherboard chipset drivers.
Is the bios level of your motherboard current?
CPU-Z will tell you what bios level you are at.
In the Task Manager it shows up as 2 cores and 4 Logical Processors and ill try updating the chip set drivers
Well, there you have it.
You are operating properly.
The cpu is actually built with two modules which some call cores.
Each module has most of the parts of a full core, but not all.
Some resources are shared.
Each module will have two threads.
But, windows deals only with threads of which you have 4.
