I have an Acer Aspire T180 with an AMD Athlon 64 microprocessor. However the microprocessor is not working. I also have a AMD Athlon 64 X 2 microprocessor. Is it okay to use this one? I checked the acer site and it said that the Acer Aspire T180 is also sold with a AMD Athlon 64 x 2 processor.
Processors, or CPUs as we call them very, very, very seldom "stop working". You usually can only kill a processor by extended extreme overclocking, over volting, strong electrical surge (which will usually only ruin the power supply) or by physically damaging the pins or the CPU its self during installation. They just simply don't go bad.
It is almost always another part of the system that has malfunctioned.
How have you arrived at the conclusion your processor is not working?
