think the athlon 5000 is cooked 0 core running 86c and 1 core @ 68c
it is an am 2 socket
well is the computer crashing or getting errors? cause if it is not then the CPU is not cooked
afraid of operating system
problems would result
the only way the OS would really need to be reinstalled would be replacing the motherboard.
sons upgrade is VERY new problem (
the only way to solve your problem is to make sure that motherboard can support that CPU your wanting to use.
