Hi,
I've just made a new computer, but the case is so small, so everything is
pack together, the power supply is just above the CPU fan. Is that OK?
At first, i got a blue screen, and then when I tried to reinstall the OS,
it suddenly handed and I have to restart again....
One time, it handed before it actually go to the POST screen, it freeze in
the motherboard logo screen....
And when I open the case, I found that the power supply is quite hot, and
the CPU fan is quite hot as well. Is that normal? Or should they be cool?
Thx a lot.

Hard to give you a good answer, it would help if you would
give a complete list and description of your computer, case
make and model, power supply make/model and size,
motherboard, installed drives, type of cables (flat ribbon
or round).

Some systems will run hotter than others, small cases will
run hot as will under-sized power supplies because they are
working too hard. Your fans must be installed so that they
work with the air, air should go IN at the lower front and
exit at the upper rear.

The parts should be expected to be very warm, maybe even too
hot to touch, but the cooler the better. AMD will run
hotter and has fewer safety features to slow the CPU down to
reduce heat. Intel tends to run cooler and has more
internal safety features.

The power supply will draw air from inside the case and blow
it out, the hot air from the CPU will rise into the power
supply as long as you have properly positioned the cables so
air flow is not restricted. (the new round cables are
important in the new small cases).

Don't know what you mean by "handed" but over heating does
take some time (unless you didn't properly install the CPU
heat sink and fan. (You must have a small amount of heat
sink compound between the CPU and heat sink [most come with
the compound installed and covered by tape (remove the
tape).]

You could have bad RAM, an incorrect BIOS, bad video card or
drivers.

Hi

Poor ventilation and bad quality/insufficient power pack should be the culprit
I would suggest you to change to a bigger chassis with good quality power pack (at least 300Watt RMS)
GTR chassis is a good choice

change the box and get a power supply of 400watts
its not a good idea to have the cpu next to the powersupply
those bluse screens are probably from overheating.
If you pc locks up alot... then its probably from the heat!
 
Ok, thx guys, I will try to get a bigger case.
And the following is my pc details:
mobo -- asus P4s800
CPU -- intel pentium IV
Power supply -- 400W ATX
case -- minitower
Ram should have no problem, it's brand new
But I got a really old video card.... don't know what kind of video card is
that.... no label at all.... will that cause any problem? the display is ok,
can't see any thing bad.
Monitor -- studioworks
Also, when i mean "handed", actually i mean computer lock up ^^" sorry for
bad english...

One thing i want to mention is I just turn on the pc for couple of mins
only, will it overheat in such a short period of time and causing the lock
up? the powersupply is quite strong, although it's sitting right on top of
the cpu fan.... And I got the blue screen as well, is that really due to
overheating?? Thx.

Most boards have a "PC health" selection in the bios. That will tell you the
temperature of the cpu and possibly the motherboard too. I suspect memory
timing problems. It does not have to be bad but if your settings in the bios
are too fast that will cause problems. In the bios, find the settings for
your memory and set them to "auto" if that's a choice. Good air flow is
important but so is good memory with the proper timing settings. Also do a
search for Asus in your news reader and find a asus group, there are
twoshowing up in mine. There other users of your board can help more.

Get a name brand quality video card that is designed to work
with XP.

New components are not a guaranty that they are good, in
fact new components are often bad.

But from what you just said, the video card seems to be the
likely cause of your problem.

You can download AIDA32 (Google will locate it for you) and
it will report on the system, including the details of
hardware. It will identify the video card and you can get
the correct driver update. But the card is probably NOT
rated for XP.

Over-heating takes some time, a driver problem happens as
soon as the video tries to do something. Heat will cause
slow-downs that get longer until the computer fails.

He means 'hanged', I think, but even that's technically poor grammar. Even
though there aren't many (if any) countries that still use hanging as a form
of punishment, to be strictly grammatically correct it should only be used
to describe people:

Guy Fawkes was imprisoned in the Tower of London and then hanged.

/not/

Guy Fawkes was imprisoned in the Tower of London and then hung.

People are hanged - computers, meat, etc are hung.

What brand is the PSU and how much did you pay for it? I ask because it
might be labelled as '400W' but, unless it is a known brand (and by that I
mean something like Antec, Enermax, Chieftec, Sparkle, Coolermaster, Q-Tech
or Zalman) I can guarantee that you can halve the output. When building a
computer *always* budget for a brand name PSU - using a generic supply that
sets you back around 10-15 pounds is the perfect definition of 'false
economy'. Known brand PSUs are designed so that, if they fail, the only
thing that dies is the supply. Generics will take out half the system with
them (believe me I know from personal experience). If it had been me, I'd
have budgeted for a brand name case (all the major PSU manufacturers now
seem to be producing their own cases) with a decent PSU (my Chieftec came
with a 360W). They also seem to have space for at least two case fans.

Also, cramming lots into a small form-factor case is just asking for
trouble - why do you need such a small case?

I suggest you purchase a midi - or full - tower from a known manufacturer
that comes with a reasonably sized supply (and you really don't need anthing
more than a 360W if it's a known brand).

I also suggest you repost this (as it's slightly off-topic here) in
alt.comp.hardware, which will be carried by your ISP's news-server.
 
Hi,
My power supply is "enlight" 400W, it's ~$60, it's cheaper than retail
price as I purchase from the wholesaler. It's brand new, i don't think it
will cause the "lock up" problem.... Also, the memory setting already set to
auto.... I tried to reinstall the OS, but then it hangs sometime during the
CD initialization stage, and when i restart the computer it hangs in the
"ASUS P4S800 page" it just so strange..... why?? And I can't even boot into
OS, so I can't really test the video card.....but will the video card cause
frequent lock up before I actually boot into the OS? Thx.

Cerridwen,

You are probably closer than I was, I re-read the OP. He probably did mean
"hung". I gave "handed" a very broad range in interpretation.

Cheers, JAX

But what about when you are using the term to describe a
part of a human? For example:

"WOW! That guy is really well hung!"

Just curious. :)
 
Really well hung has at least two meanings...
Judge Roy Bean said, "That man was really well hung!"

John Holmes.

Well if you're talking tackle then you're correct! Hanged refers to capital
punishment.
 
There should be a FCC label and some sort of FCC number on the back of the
card.

If I remember correctly, you can search for the company with the FCC number
from the FCC website.

And for the hanging problem, I will boot the computer to DOS, and just let
it get hot to see if there is any problem.
 
Download the shareware program Motherboard Monitor

http://mbm.livewiredev.com

It will provide you will real time monitoring of all your motherboard sensors, such as temperatures, fan speeds and also voltages. This program is a must if you are overclocking or building your own system. Last time I checked, MBM was freeware, but the author accepts Pay Pal payments for his work (which is excellent IMHO)

Ok, I will try the MBM, thx a lot! Hope I can find out the cause. but
normally what's will be the reason for the "hanging" ^^" problem?
Thx..
