The problem is in the PSU. If your power supply is old it will slow down the current even there is enough voltage. Check also the thermal paste of the component it can be dry and the parts are dirty and the cooling system is poor.

Heat problem.  You have old CPU cooler still?  Full of dust?  How about the box fans--running fine?  Try an accessory fan blowing more air through.  That new video card might be too hot.  You can monitor temps with software.
