windows vista reboots when idle

Hello,

I can work normally while using the computer, but if I leave the computer idle after 15 minutes aprox. the computer restarts by itself.
I didn't get to see it in the moment it is rebooting as usually I am not close.

Sometimes restart normally and sometimes a black screen with the message Press f1 To continue,f2 to Run the setup utility. Press f5 to run onboard diagnostic

but only work f2 and after shut it down and turn it on again everything works fine till the next idle moment.

This problem started last week after a windows update so I wonder if that could be a clue...

Dell xps M1710

Windows Vista Ultimate
Service Pack2
Processor: Intel (R) Core (TM) 2 CPU T7600 @ 2.33 GHZ 2.33 GHZ

Memory (RAM) 2 GB
System type 32 bit Operating System


I'll appreciate any help.

Thank you

Ok, I'll start working with the updates to see what happen and I'll let you know...
Thank you for your help, plodr ...

 

Hello plodr,

Sorry for the delay, but I was trying to do what you suggested.

I uninstall the first update and the computer started to crack so much that have to install it again.

I tied to restore it to a previous date before updating and never can be done. The computer reboots before it can be finish, so I decided not to insist.

So I managed to stop the automatic restart after the blue screen and got to see the error legend in the blue screen as following:

KERNEL-DATA-INPAGE ERROR

Technical Infomat:
STOP: 0x0000007A (0xC0604000, 0XC000000E, 0x7EDD4880, 0xC0800000)

Hope that can give a clue of what's going on in the system.

Thank you for your help,

 

Hi DavidGP,

I didn't try in safe mode. I'll check that and let you know.
If the blue screen doesn't show in safe mode, do I need to run chkdsk?

Thank you,

Ok, thanks for all your help!

 

Hello DavidGP,

Sorry for my delay, I wanted to check that the system was free of viruses so I was in malware section doing all the upload logs. All came back clean after the experts reviews.
The laptop was working actually very good beside the fact that reboot when idle, but suddenly today the screen freeze and since then I couldn't start the computer.

Blue screen
STOP:C0000218{Registry File Failure}:The registry cannot load the hive(file)
\SystemRoot\System32\Config\SECURITY
or its log or alternate
It is corrupt, absent, or not writable.


Tried safe mode, from the last good configuration... and nothing

I ran chkdsk several times and fixed something on file9 (no idea what is that) and never complete the process as it reboot in the blue screen...

Unfortunately, this laptop had original windows xp and then updated to vista, I don't have the original vista cd to recover the start up.

any help I would really appreciate it!!!

Thank you,

 

We really need to have it finish that chkdsk. Can you try again?

 

Hi Adrynalyne,

I tried several times but when is starting step 3 (contracting stream... ?) seems like freezing and after a couple of minutes the blue screen...

I was looking for my Windows vista Recovery copy, but can't find it either. I'm stuck.

I will try again with chkdsk but do you have any other suggestion?

Thank you,

 

all horrible now
didn't allow me to run chkdsk from the start up
how can I run it from dos?



thanks,

 

Boot to the CD and use the command line.
