It's unlikely that your CPU is at fault.  The few times I've ever seen a CPU
go bad, the system wouldn't stay up for more than a few seconds. Much
more likely is bad memory.  A system that comes up and then crashes
can do that with bad memory.  The memtest86+ CD will let you test
memory easily.

I'm not up on Linux tools to test disks, but I have used disk manufacturers
disk test tools with generally good results.  dd is also useful, when 
reading
a raw partition.

As far as upgrading goes, I always make a full backup first, and then also
make a backup of /etc and other places that hold config files onto a usb
stick, so I can use them when building the new system.
