Re: Chaintech CT-7NJL6 not booting properly

I just purchased the Barebones kit from TigerDirect with the
Chaintech 7NJL6 mobo(w/ AMD Athlon XP 3000+) and added a 250GB HD,
1GB PC3200 + 512MB PC3200 RAM with a Chaintech GeForce FX 6600 video
card. It has a 500watt modular PSU, but it will not boot. It powers
on and the fans all spin, but there is no display at all. The memory
is firmly seated and I have tried disconnecting everything but the
memory and video card, but still it doesn't display. Any ideas?
Thanks.
Just noted the modular PS. Another area of my suspicions. I have an
Ultra 400?. This is twice as many power connections to not make
properly. And their connectors didn't exactly follow the AMP
origianal, maybe patent licensing. Result is the pins/sockets don't
float in the jack/plug. And they are not gold plated. If tinned pins,
they usually contain some level of lead as in solder and it easily
gets a dark oxide coating that doesn't conduct well. (Look at car
battery terminals, not the fluffy stuff but the dark) This is easily
removed with scraping action or plugging and unplugging a few times.
To prevent it from coming back, I used a stiff silicone grease
intended for automotive bulb sockets. It is a white transluscent
grease but slightly thicker than that silicone tuneup grease. If
uncertain about conductivity, check a dab of it with a meter set to
high resistance scale. You want it non-conductive. Place or smear a
small amount into/onto each contact. Make connection a few times to
help spread it and coat the contact surface. Also the main power
cable is quite stiff and depending upon your layout is likely to put
an inordinate amount of lateral pressure to the connections. Try to
preform the cable to relieve this strain and in my case that included
a single loop midway. That outer plastic casing molds better with
warmth.
Also I read of some cases having shorts in the front jacks. Leave
temporarily disconnected.
