Services will not load (No device manager, disk manager, etc...)

Hi,

I have loaded a fresh version of x64 on a system. It is the only OS. It runs
fine for a while then at random it loses services. I tried to open device
manager and it shows a blank page. It says the "service cannot be loaded". I
get the same with other services. I have run CHKDSK /r with no change. Any
suggestions? Originally I thought this was a dual boot issue. However, now
that I have wiped the drive and started fresh with just x64, I am lost.

Help!

If you shut the machine down, come back in a half hour, and start back up,
is it OK? Or are there still problems.

I'm suspecting a hardware problem, probably heat related. The first place to
look is overall system cooling and memory. I'd start by disabling any
overclocking you might have enabled, and running a thermal diagnostic tool
(most mobo mfgs ship one with their mobo these days on the driver/utility
disk). Also, a good, thorough, memory test. For more on possible testers
and solutions, see my blog:

Charlie,

I will check on the temp. I had thought everything was within limits. This
was the firxt 64 bit and x64 system I had built. Can you tell what the
acceptable heat limits are for the CPU? Maybe I did not read that right.

THX for you response.

I'm not sure what temperature a CPU is considered overheated, but I never
like to see mine above the mid 40's. And the behaviour of my server since I
put it in a new case with better cooling is definitely more stable. The CPU
there never goes over the upper 30's.

(I'm sure someone will jump in here and say they're running in the 50's with
no problems. As always, YMMV.)

 

I am quite sure that the temp. is 45 degrees for a specific room temperature
and airvolume that I cannot remember. These are the test parameters and may
not be directly transferable to an average room in an average appartment.
This test room is probably bigger, which means your CPU should probably run
colder.

I've had typical figures of 49 degrees and rising to 54 when working
harder - one game, with one card pushed it to 70 degrees which was when the
system turned itself off. And this is probably the real critical figure, but
then it is critical.

Going somewhat above the safe temperature is probably not immediately
dangerous for the equipment in any way, but it will shorten the CPU's life +
it runs faster when colder, so we are quite naturally interested in the
environmental status?

Of course, for the tech people the critical point is when the system as a
whole [may] stop being stable, the event window is probably quite wide but
the bottom line is that when hot - anything may happen.

Personally, I start thinking about this if the air that escapes through the
vents seems hotter than my breath, then I check both front and back to be
sure, and make investigations on what can be done about it.

Thanks for the specific details. I'm with you on what I want to see for
actual temp in the real world. The only exception for me is laptops, where I
expect the heat coming out to be a bit more.

Charlie's numbers are probably very conservative, but very acievable. I
almost never get above the mid 30's cpu and the chipset may reach 39, and
that is with the cooling fan not working as I haven't had time to replace it
for the third time. I do have a side fan which blows on the cpu, chipset
and memory.

 

Quite true, Charlie. But that doesn't mean that we should expect the CPU
temp to be significantly higher, it runs in a smaller space and if it is
well designed the hotter exhaust wouldn't have to mean a hotter CPU. A big
fat Desktop has a volume of 35 - 40 liter of air in constant motion, whereas
the laptop blows out a concentrated jet of hot air.

I can't say that I've checked the temperature on my laptop regularly, but
right at the beginning I was interested and the figures where pretty normal
as I remember. What I have noticed - is that it seemed slightly hotter when
on batteries. Meaning, perhaps, that the ventilation is more reliable when
socketed. Might be worth checking when moving around on a hot day?

Mine stays at home almost all the time.

Try running a Core Duo in a MacBook Pro. Temps in the range of 180 F.

 

Logaritm head math is not my strenght, but 100F's is 38C's and 200 isn't 76,
but that has to be over 60C's?

You need a fluid helium cooler!

82 degrees C. Now that is hot.

Yeah, my mobo was running in the upper 50's, and the CPU peaked out over 60
before I changed to a good case. Now it makes less noise and both run in the
mid to lower 30's. That has GOT to be better!

 

Apple's tart (nice pun, huh?) replies have been that Intel puts the top of
the operating range at 100C and that their disclaimers already warn against
using it as a laptop ("may cause discomfort or even burns").

Apple insists that the MBP is not a laptop, it is a "notebook" computer. As
it turns out, Apple has determined that thermal paste "may have been
misapplied" during manufacturing.

My own MBP gets pretty warm but not anything like some of the descriptions I
have read. It is a pretty nifty lap...er...notebook.

 

Charlie, Tony, Colin,

Thank you all. I feel I need to supply you with more info. This is an Intel
830 Dual core on an Intel 945 Mobo. It is in an Antec case designed for a
server with well beyond normal cooling. I have built many systems but this is
my first 64 on 64 with dual core effort. I thought that the core temps for
the dual chips was much highter than a normal chip. Anyway, the problem did
not go away after allowing the PC to cool down, even over night. I just
removed system mechanic (designed for x64) and let XP reinstall under the
repair function. So far, everything is working fine. I have to wait and see
if the problem returns. I appreciate all of your help. I will post another
message if the problem returns.
