My Computer keeps shutting off?

My Computer keeps shutting off?

I bought a new PC Power & Cooling ATX 360 power supply. It is still doing
it?

After it shuts off, the power button does not work. I can either do the PC
Power & Cooling thing where I connect the green & blk wires or flip the
110-220 switch on the back, wait a minute & it is ready to go again.

It is very erratic. There does not seem to be anything that triggers it? I
am guessing it is hardware?

I have checked all the plugs, etc.

What gives?

If it's new, take it back to the shop and get one that works. Be sure
and arrive at the store when it's full of customers and loudly state
your problem so everyone can benefit from the answer.

What about the CPU cooling fan and any fan you might have on the video
accelerator chip? Have you tried software for monitoring your fan speeds
and the case, CPU and video accelerator temperatures?

 

[Richard]

Great idea... I took it apart & the fans are running ok. The AMD cpu temp
ranges from 141 to 161 f. That may be a little higher that I remember from
before? Right now it is 141 f with the cover off. I am going to try that for
now?

That sounds pretty toasty! I had trouble figuring out what AMD considers
too hot. I don/t know which model CPU you have either. Maybe the
Dashboard Demo Software at
http://www.amd.com/us-en/assets/content_type/utilities/dashboard.exe
would tell you what range is acceptable for the model of you are using.
You might need to install one or two supplemental case ventilation fans.
Experiment with aiming a table fan at the open case to see if the system
works better.

 

[Richard]

Thanks for sending the >Dashboard Demo Software

It didn't work for me since I think it is for 64 bit system. Mine is older
than that. I think it is a 2400?

The mother board says it supports a Socket-462 for AMD Athlon. PC Alert is
giving me the CPU temp. If that is the problem.... why is it failing now?

Waaaay too hot. I have an AMD AthlonXP 3000+ and it's at 95F and the
computer has been on all day. Replace the fan that cools your processor;
it must be going out. It might set you back 5 US dollars, max.

Many of the better power supplies have thermal overload protection. If there
is a short anywhere on the M/B, the power supply will shut down. Recycling
the power will/may reset the overload device.

I have had this happen to an Antec 400w power supply. I found the wires that
were touching and separated them. Everything was then O.K.

Athlons have a spec that lists either 85 or 90 deg centigrade
(depending on the model) as absolute thermal maximum. Meaning the chip
isn't dead (yet). The stability threshhold is lower. Around 70. Which
you have exceeded. Chances your motherboard is going into thermal
shutdown in order to protect your chip.

85 centigrade works out to 185 farenheit

Take an air compressor to that computer, blow out all of the dust from
the fans, intakes, and heatsinks (may as well get it off the rest of
the computer too). Dust is the enemy. It acts as an insulator and it
clogs your airfrow.

If that doesn't lower it, re-do the heat sink. Take off all the old
thermal paste (or tape) and put a new layer on.

If that STILL doesn't cure it, get a better heatsink, and maybe an
extra case fan.

 

[Richard]

Richard,
Were the wires insulated? Where should I look?

Richard

 

[Richard]

I really don't have much dust, since I try to keep it clean.

I am going to look for another fan, etc. With the cover off - it is running
in the low 70's C.

Look everywhere! I had a short in an IDE power cable.

I want to thank everyone for all the info ... I think I have solved my
problem by replacing my case. I only had 1 cooling fan besides the power
supply. I have replaced the case & the temp is 20 deg C cooler. Also I
always cleaned the dust from the CPU fan, but this time I took it apart &
found some dust that I couldn't see.

Thanks again ....
