C64 Problem

Hi,

I recently got a C64C plus VC1541 (not VC1541-II!) from ebay,
and it shows the following symptom:

when I connect the new C64C with the VC1541, when I start loading
anything from the disk, the C64 resets and the floppy hangs.

So far so bad, I thought this is either the floppy or the C64
hardware. Now when I replace the C64C with another C64C, it works.
But, using the broken setup, when I replace the VC1541 with another 
VC1541-II, it also works!
Anyone has an idea here? Both new (C64C and VC1541) have seemingly
unbroken warranty seals - so it seems no hardware tinkering.
Only the C64C had a plug on the tape connector with a 
resistor between the two outmost pins. It does not matter, however,
whether this is plugged in or not.

Another question: The new C64C has a serial number in the 100000s
and an old-style (like my original C64) power supply. The other
C64C has a brick-style power supply, it has a serial number in the
500000s. The pins in the power plugs of those power supplies
are different. Can I actually exchange them?

Many thanks!
Andre
