Hi, Is it possible to blow up a CPU (or mainboard) when swapping CPUs on a U5 or U10? I had a non-working U5 and put in the CPU of a working U10, but now nothing works any more. Cheers, Walter. -- Walter Belgers "Si hoc signum legere potes, operis boni in rebus walter at belgers.com Latinis alacribus et fructuosis potiri potes!"
