Set Windows to save minidumps. If you already have some in Windows > Minidumps, copy the last few to the Desktop, zip and attach them here, I'll try to debug them.

How to attach items to your post.

 

First of all thanks for replying. i did try to save those minidumps but i can't find any folder as minidumps. I also changed their directory but still nothing . but when i go to event viewer i get this

thanks

 

Ok, if you back to the System log, can you save the log as the default type, zip and upload it please?

 

i don't know how to do that ..but i have saved all critical errors into .evtx logs and zipped it....

 

That tells me nothing, I'll need the unfiltered log.

 

how do i do that ??? pardon me but i am kinda n00b at these things ...:confused

 

Go back to Management > System log and save it as it is, we need to see if there's anything logged before or after the Critical errors that might help us pinpoint the problem.

 

ok cool.. got two files .mta & .evdx


everytime i try to attach the system shuts down so i have uploaded (zip) files to google docs

No i can't use the pc in safe mode .... it will shut down automatically and occasionally i get a blue screen of death.

on to second question . no there are no yellow marks

3) At first i had xp ..started giving me troubles so i installed windows 7 via usb.... so you can say it is a clean install

thanks for the help

 

The minidumps will be stored in C:\Windows\Minidump, currently, it looks like you're PC is set to overwrite = only store the last one. Can you set it not to overwrite please? If there is a file there, copy it to the Desktop, zip and attach it.

The System log shows nothing I can pin this to. The MTA file means nothing to me, I don't have MS Flight Sim. If you can attach the Applications log file, it may show something relevant.

I read something recently that suggests the onboard nVidia gfx chips are highly susceptible to overheating, even a fine layer of dust on the cooler can lead to crashing, check and clean the internals again. Install something like HWMonitor so that you can monitor temperatures.

 

Here are my pc temperatures

how do i set not to overwrite it dumps. i researched on the net about dumps and saw that i can manually create dump files

so which dump file do you need . i am uploading all my processes here.

No, that's the Security log, I'd like to see the Applications log please.

 

ok...once the system crashes and logs have been created i will upload it here
