pc restarts on it's on

[iecus]

I've been fighting w/ my pc trying to figure out why it keeps rebooting
all of a sudden, not right away but some mins will past then reboot. I
thought it was my firewire card it's been having problems seeing so I
took it out. I went into safe mode and ran a virus scan w/ my panda
titanium, regcure for bad registries, noadware and lavasoft. they found
some things and they all cleaned or deleted everything. Rebooted and
thought it was fine until it started doing the same thing with and
without my firewire. I did a search here and found a memtest program so
I ran that for the hour and came up clean. the only other pci I have is
my video and audio. I found the problem to be the software that's
suppose to help me which is the PANDA antivirus. I notice it safe mode I
can be there for a long time w/o it rebooting and that's because all the
software was disable. now I disable the panda and it seems to be ok.
Anyone using/used panda and found it doing this. Now I have to find
another anti virus software. what are you guys using. Tried mcafee
before, it wasn't working that great for me. anyone using the MS beta
virus software?

you could take a look at the start up and recovery dialog and see if there
are options you can enable/disable. Go to control panel, systems, advance,
startup n recovery. There you will find the option to reboot upon an error.
It sounds like this is occurring to you now. If you disable it, the machine
wont reboot by itself and display an error message. Afterwards you would
hav to reboot manually. Check to ensure that you have a memory.dmp file and
setting. Mine is set to complete. So this setting could help you too.

You know, I'm not sure why your memtest took an hour. Seems not to be a
good indication. To give back some memory, you should disable all your
startup programs from msconfig via run via startup. When you reboot, you
can see how windows seems and maybe double check if something in your
startup was causing the problem. Could be poorly written software, trying
to access the internet for updates, downloads, registration, etc.... and
overwhelmed your system....

Basically there is a lot that can cause the problem. But you can also look
at the logs via admin tools and see what processes were running just the
milliseconds before the crash/reboot.....

Which memory tester did you run...Try microsofts,go
to:http://oca.microsoft.com/en/windiag.asp Download and install to a MS-DOS
formatted floppy,then boot to floppy.Also,memory testers,do take an hour
or more to run the tests,if you run in its advanced tests,probably 2. Also,
you might try running MsConfig as described in kb310560 This is where a
microsoft tech would start.....

Hello iecus,
Please do this:
A) Right Click the My Computer icon on desktop. Select Properties.
Next, select Advanced. Look for a block that says Startup and recovery. Press the settings button.

In System failure section, turn off (un-check) Automatically restart.

Write an event to system log should be Checked (selected).
Apply change.

If you should later on see a STOP error, write down all of the codes and text. And then you can do research (as well as posting here).


B) See what Event Viewer has in it's log. Select Start button/ select Run , then type in

eventvwr.msc <Enter-key>

-- or Go to Control Panel / Performance and Maintenance/Administrative Tools >Event Viewer.

Review the sections and look for Errors or Warnings that match the time the event occurred.
Double click---the information "may" give a clue.

C) If your RAM memory is indeed bad (or even if you have some pc overheating), that can very likely be the cause for reboots.
MEMTEST86 is a memory test utility & is free.
See http://www.memtest86.com/

I would recommend you download it from a "reliable" pc --- not this one. And do the setup and the diskette on the good system.
Only then take the diskette to the "problem" pc. And run it to check your pc's RAM.

I've been fighting w/ my pc trying to figure out why it keeps rebooting
all of a sudden, not right away but some mins will past then reboot.

Disable Automatic Restart on System Failure. Here are the steps to disable
this feature:

Control Panel (Classic View) > System Properties > Advance tab > Startup and
Recovery Settings button > Uncheck "Automatically Restart".

Now the computer should display a STOP code, for example [0x000000E8 (
0x00000000, 0x00000000, 0x00000000 )] when a system failure occurs. Post the
STOP code for more assistance or go to the following web site for
assistance:

Ok guys thanks for all the help thus far. My memory is fine, I ran
memtest. MS memory test and a 3rd memtest83 everything is fine. right
now I disable my zone lab firewall to see if that allows it to stay up.
prior to you guys mentioning it I did disable the restart error option,
but guess what, it doesn't restart nor give me the blue screen w/ the
error it's just a black screen and I have to reboot. according to my log
there where errors while I was on and 1 of the last errors happen
around 9:30 but I didn't get off the pc until around 11 and it was fine
then. databaseben mention to check memory.dmp where would I find that?
this is the last transaction in the event viewer log since yesterday.

this is from the application

the event viewer is a log that can be found under admin tools. I think
there is a performance log somewhere there about too. The location of
memory.dmp file (if one is being written) can be found in control panel,
system, advance, startup/recovery. Near the bottom, there is a window with
the taget location.

Just some fyi, my pc is set to complete memory dump. Maybe this will help
too.

Just as an after thought, did you happen to disable your startups so that
you could temporarily release as much memory as possible? This would help
in determining if there is an illegal startup crashing your system. Also,
I'm not an expert at reading into error codes. But it seems that there is a
mention that system restore was able to get some free disk to resume.

You should double check to see if you have any disk space left, if your
pagefile/virtual memory is the right size and see if your restore settings
are set to maybe 5% of you disk size. I don't remember the exact
percentage, but you probably have an idea of what to look for....

so far so good I will see by tonight if it cuts off again, it could have
been the zone labs, firewall. it has not shut down since I disable that
from the start up.
