Right Tim: Being able to switch accessories to a different machine is
a good way to troubleshoot. I can do that here but many have only
one machine. I just wanted to point out that, sometimes, problems
that seem to come from the PAR are totally unrelated to the PAR. If
you think about it the +5v supply takes a very heavy hit on current
and a 200 watt load is 40 amps. Amperage is what determines the wire
diameter. Those little 22ga wires that connect the power supply to
the MB are barely marginal and the plastic connector certainly
isn't. It may have been adequate for the typical home PC but those of
us using targa+ and PAR, and TBCIV with 32 megs of RAM plus a DX266
CPU are pulling this kind of current. You can put fans on hard
drives and fans on CPU's but if that connector is hot hot then the
voltage to power all this stuff could become intermittant, causing
little glitches in files. It has happened here and to a friend of
mine in town.
