since ive had my computer (about 1.5 years), it would randomly (though
not too often) have a very sudden reboot. as in just instantly reboot
at completely random times. i check my bios to see if its from my cpu
overheating or anything, and the cpu doesnt seem to be running any
hotter than usual (though it still runs really hot). can anyone think
of a reason it would do this? i have a a7v333 with a athlon xp 2000+.

PSU - check your voltages are in spec.
Memory - check with memtest86
Heat -> CPU errors -> check with Prim95 torture test.

Just how hot is "really hot"? And is that socket or CPU Diode temp?

err 70C :)
i had some problems over the summer where the bios would lock my
computer if it decided the cpu was overheating (75+), and i fixed that
up with just messing with circulation and cleaning up case/dust, etc.
i ordered a better fan but the bastards sent me the wrong thing and i
got lazy. other than this, my system is stable as a rock. i commonly
have uptimes of over 3 weeks without a hassle. but lately its been
doing this a lot.

if any of these matter:
mb @ 37C
CPU/power fans: 2500/5400 rpm

nothing seems out of the ordinary.

You have not mentioned what your system comprises - hard drives, memory etc.

However, Athlons (and P4s) draw most of their power from the 12v rail, and
yours might well be too low for your system - 18 amps is becoming a sort of
minimum level.

I had a problem with my system recently using the A7V8X
motherboard where it was randomly rebooting. Turned out
it appears to have been my 2 year old IBM 60G hard drive. Also
noticed that it was taking Norton AV almost 4 hours each
night to scan the hard drive. Replaced the hard drive and
have not had any more problems. Seems a little strange
but I hope that was really the problem.

Regards,

James

Have to excuse any repetition/confusion as BT internet are being
exceptionally crap as usual and can not even manage to get all the posts in
a non binary newsgroup

so if it is running at 70C that is hot - and vcore is bit high - have you
set this for a reason or is it a palomino and is really at 1.75v being read
as 1.82v. May try setting the vcore lower - or getting a bit better hsf.

Might not be the machine even - it could be drops in the supply voltage from
your electricity supplier perhaps switching loads a fraction of a second too
late - nothing else will be effected such as tv, or lights - but the
computer will reboot.

Also might be a local load switching such as a large heating element, an
inductive load such as large amounts of non tungsten lighting or a motor
(such as may be found in some parts of an education establishment or crappy
halls of residence supplies) - do you have a UPS you could use/borrow (for a
long time) - preferably a smart one that will log supply fluctuations and
alert you if this is occurring.
 
Hi,
What OS are you using? If it is XP then turn off the reboot when you get a
BSOD. That way you can see what is causing it to reboot.
Go to control panel-----system------advanced and uncheck the "automatically
restart" check mark. This will stop it from rebooting automatically when
you do get a BSOD. that way you can actually see the BSOD and get some info
from it.

I would say that a 300 watt is a little light, unless it's a really good
one, and even then I would probably replace it with something a little
heavier, You can get a good one from Newegg for about 45 bucks, I have one
and it is an Allied (AMD recommended) it's 450 watts and I run ALLOT of crap
on my machine, 3 optical 3 hard drives 6 fans, and 2 cold cathode
lamps......

70C seems a bit high too, I'd try to get it down to around 45C to 50C
I have a Barton 2500+ overclocked to 3200+ and it never gets above 50C I
read the specs for the Barton core and it's not supposed to get over 80C
according to AMD, I'm not sure if it is the same for yours but most likely
it's close.
Good Luck,
Bitsbucket

yes, it is a palamino.

i dont think it is this as it has happened at both home and at school,
and while at school happens to none of my suite-mates, or anyone else
in the area that i know of.

i unchecked the automatic reboot as someone suggested, and noticed in
the same section that there was something that has been logging the
errors. sure enough there is one from today. the file is a .dmp file,
which i am not sure how to do open (it is not fully text). there is
some text in there.. many .sys and .dll files, all seemingly
unrelated, and the beginning is all just PAGEPAGEPAGE.
any ideas?

Do you randomly press the reset button?

I had to ask.

It does matter. Although your psu may fine *overall* with a 300w rating, the
12v rail looks a bit suspect. Your xp2000 (if a palomino) draws about 7
amps, your 2 hard drives = 4 amps, mobo + fans = .5 amps and a cd or dvd
drive around 1 amp. Total is around 12-13 amps. Most of the time you could
be OK, sometimes not, hence possible random re-boots.

yeah well i got it again, it was a blue screen that was automatically
rebooting. the error was with vsdatant.sys , which from a google
search appears to be a file asscociated with zone alarm pro. first
result suggested i update my video drivers, so i am doing so now. i
also have updated my copy of ZAP. hopefully these steps will work.

if your running windows xp there was an article on tom's hardware that said
use a minimum 350watts power supply
