Hi All

 

I have a Windows XP SP2 box which I assembled. It has been working fine for

teh past three years and I have never had major issue. Recently however it

has started to simply reboot itself for no apparent reason. I did change the

power supply in Jan 2007. What happens is that I am working on something and

- boom - the machine restarts. When it comes back alive, I DO NOT See event

ID 6008 indicating a drty reboot. This really puzzles me. I then did a filter

for event log events and noticed that I only see events 6009 and 6005 in the

sequence. I rarely see 6006.

 

Now, if a machine simply restarts, should I not see a 6008? Why doesnt my

system log it?

 

I have been told that this may be a hardware problem... either power supply,

or RAM, or mother board. I am willing to check out the hardware but I still

dont see why a 6008 should not be logged on a dirty reboot.

 

Any ideas on how I should proceed on this one?

 

Thanks

Overheating? When was the last time you cleaned out the dust from your

cpu fan and any intake case fans with a can of "compressed air"?

One tip ... disable the system from rebooting on errors so that you can

actually see the error message. Right click My Computer, choose Properties,

click the Advanced tab. Click the Settings button under Startup and

Recovery.

Uncheck the box next to Automatically restart. Click OK.

 

That's a really dumb default XP setting, if you ask me. How would one ever

know what the issue was if the system kept rebooting ?

 

Alternatively, when's the last time you cleaned the tower? Check your vent

fans for debris and the insides of the tower for dust bunnies. Heat will

cause unusual events and being that this is the summer season in the US, you

may be having problems because of the aforementioned dirt.

 

It's summer folks, let's keep our systems well ventilated ;)

 

Good Luck :!:

random reboots are typically caused by:

 

bad ram

bad power

overheating

a driver issue

 

as recommended, turn off auto-restart-on-error so you can see the exact

error BSOD. That may provide some insight, especailly it it repeats w/

the same exact error over and over again. If not it truely is random.

 

advice has been given on checking for excess dust etc, and verify that

airflow thru the case is not restricted (flat cables should be tucked

away). Check that all fans are running, the internal Power Supply fan

too.

 

get a monitoring utility for your motherboard to check temperatures (check

maker's site first, or goohoo for "Motherboard Monitor" for a compatable

generic util; make sure it lists your MoBo model before trying it.)

 

use memtest86+ to check ram; it should pass with ZERO errors, anything

else is unacceptable. remove and reseat the ram sticks to wipe their

contacts clean.

 

have you altered a driver recently? are your drivers "resonably" up to

date? You do not always need the latest version driver, especially video,

but you should check out what fixes have been made - if any apply to you

then it's worth an update. Video drivers are the most troublesome to

update, if yours has been installed and working fine for a while I'd leave

it alone. Often video driver updates fix/accomdate things in new model

boards, support for the older boards doesn't really change, so going to

the latest driver when your board is 3 years old is a waste.

 

and beware driver updates from Windows Update - these are updates to MS's

own drivers, and they will gleefully overwrite any manufacturer's version

you may already have - you are always better off using a driver direct

from the maker. If you know you're using an XP default driver then sure,

take the MS update, otherwise turn it down.

 

as far a power supply issues, the only way to be sure is to swap it out.

they do fail, especially the lesser-name brands. By all means check all

power connectors when you're in there cleaning the dust - slip the

connectors off and re-seat 'em. Often that will wipe the pins and

reestablish a cleaner connection.

 

good luck

Thanks much Frodo (and Plato and KB)

 

I did not mention in my earlier post, but I had already cleaned my system

using a vaccum cleaner, reseated cards and cabled and RAM chips, and had

checkedd driver updates, etc. I had also unchecked the restart option. So,

whatever was causing the reboots was something else.

 

My fundamental question still remains unanswered. If my PC is restarting

(whatever may be the reason), shouldnt Windows XP not log an event id 6008

indicating that the rpevious restart was dirty? Why is my system not logging

it?

 

BTW, I have bought a new 400 watts SMPS and will see how this behaves.
