can anyone help me? i upgraded my cpu but it fells same
Yeah that's what often happens if change to a higher core cpu. Usually Windows checks number of processors in msconfig > boot to force the amount of cores as before to make sure the os boots. Just needed to uncheck number of processors option and reboot.
