Just when things were going so well with my C64...

Garbage appeared on my monitor screen, munching its contents, and when I
disgustedly turned the machine off and on to clear it, well it didn't come
back on.  The power light stayed off.  So I opened up my C64 users guide,
which told me that I had a bad fuse, and that I should take the machine
to an authorized dealer...  I decided that, since the warranty had expired,
why pay them to do what even I could do--replace a two-bit fuse.  I opened
up my machine, and, after carefully unplugging the power light and keyboard
connectors, removed the top half of the case.  I found the fuse right away;
there is only one in plain sight on the PC board.  The next day I took the
little critter to Radio Shack, where I learned that the fuse might be either
a regular one, or a slo-blow one.  Just to be safe, I bought the regular 
flavor.  

The next evening I installed a new fuse, closed up the case, and powered
my machine up.  I was very disappointed when my screen stayed blank, until
I noticed that I hadn't connected it to my 64!  Once connected to the monitor,
all worked perfectly.

The next day I was typing in a program, when garage appeared on the screen,
and when I toggled the on/off switch...

The bottom line is that my new regular fuses fry in anywhere from one second
to one day, and I suspect that I really want a slo-blow fuse.  As you may
have guessed, I'm no hardware guru.  I would appreciate any help on this
problem.

Should I use a slo-blow fuse, or is there something else wrong with my
64, which causes it to burn regular fuses?

Note:	In my Programmer's Reference Guide is a schematic, which says
"1A" next to the fuse.  The original fuse said "1 1/2" on it, and had
a zig-zagged filament (not spiraled like the slo-blows at Radio Shack).
