Windows 7 Pro Crash

My PC, Athlon 64bit x2 with 4GB RAM runs W7 32bit.

I have had this not running for a while as I been using my laptop. When I started using it again it started to blue screen, this is intermittent and not linked to applications (as far as I can see).

I have done the usual. Updated all drivers, Win Update, Kaspersky full scan, check for power supply issues to component and the compulsory check for fans and dust re overheating.

All to no avail. Still happens ever so often.

How can I go about diagnosing the reason, is there a log file for the blue screen, that can be analyzed or do I need to have MS tools for dissecting dump files?

Any help will be appreciated.

Thanks
capt.

Starting with the message of the blue screen would be helpful ^^

you can download bluescreenview that will automaticaly connect to your dump files when it is opened.  then you can use that information to get more help.

Probably RAM going bad.

Try running memtest to see.

Additional info: Windows creates a memory dump [ .dmp] on your system partition at every BSOD.

The only exception is, if you don't have a page file [swap file] on that partition you will not get the memory dump.
I found out the hard way.

Upload the .dmp file located in windows folder for analysis.

Event Viewer (which you can reach quickly by typing eventvwr.msc in the Run dialog box) is normally so full of events in the log that searching for problems can be long and arduous.  But a very good way to go directly to the problems logged by the event viewer is this:  go to Control Panel -> make sure the View by Small Icons is chosen rather than View by Category -> click on Performance Information and Tools  -> click on Advanced Tools -> click on View performance details in event log.

As they are random reasons it seems more likely that it is a RAM issue?

Would suggest that it is not a particular app or file/driver but whatever runs at the time the PC crashes...
0
 
Netman66Commented:
It seems to be consistent with ram going bad, yes.  Only the memtest run overnight (multiple passes) will uncover an issue - unless it fails pretty much right away.

@StoneG:
You made a comment that got my attention.  Are you suggesting that if one has Windows installed on C: but the swap file is on a different partition, there will be no dump files after a crash?

If so, this is very significant!

Prester JohnCommented:
It would be a good idea to run System File Checker after you check the memory.

The following link gives you the step-by-step: sfc

Prester JohnCommented:
sorry

Run sfc /scannow from a elevated command prompt.

will run sfc and upload minidump Monday. Time to go home now. Memtest is running and is complete 31%...

RAM test did  not show up any errors, have left the PC on in locked state now, but no crash since Monday.

Fluke.

I am sorry but there are so many other things going on right now that I have not had any chance to follow this up.

The few times I had a chance it behaved normally...

One update:

sfc /scannow

Beginning system scan.  This process will take some time.

Beginning verification phase of system scan.
Verification 100% complete.

Windows Resource Protection did not find any integrity violations.

OK, more than one week without a crash, I have been trying to upload the DMP nut got knocked back as it is too large (269Mb >>>zip 84Mb)

Prester JohnCommented:
That's pretty big.
Have you tried looking at it with BlueScreenView to see if there's anything that jumps out at you?
This TechNet article was originally for NT but the error messages are still pretty much valid I am told. They are near the beginning of the article & might give a clue or two.

>Are you suggesting that if one has Windows installed on C: but the swap file is on a different partition, there will be no dump files after a crash?<
Sorry. For some reason I thought I had responded to this, but apparently I didn't.

****

Yes. That is correct.
I have not done this on my Win 7 but on my XP I have the swap file on its own partition.
At one point I got a BSOD and was anxious to try out BlueScreenView.
No dump was available.
I created small swap file on C: [I think it was 80MB] and the next time I blue screened I had a dump file. [  I had a bad video driver :-)  ]

This has now been up and running without fail for a whole week, I cannot fathom what the problem was. I cleaned out the cabinet so maybe it was a heat issue??

How to close this? Any ideas?
0
 
Prester JohnCommented:
Coulda been a heat issue.
Were there lots of dust dingos & cobweb critters?

It might be that everything you did got rid of some little something that, by itself, was not an issue, but collectively caused a "rogue wave" type of crash.

Closing this Q is your call. There was no apparent solution provided.
If you learned things you didn't know you might spread the points, but that's just one option.

Maybe you should leave this open for a couple of weeks and see if the BSOD monster wanders back?

captainAuthor Commented:
Good idea, I will give it a week and then split.
0
 
PhoenixkeCommented:
Could simply have been an error in the swapfile. Perhaps you reset the swapfile while testing for other causes and this could have cleared it up.
I've had the same problem a few times now while working with various versions of windows and deleting the swapfile cleared it up everything for months on end.

captainAuthor Commented:
I will have a go at deleting it again just in case...

thanks for the info.

captainAuthor Commented:
OK, I think it is heat related. Today the PC just crashed without dump file, and also shut down half way through reboot. And today is a hotter day than usual. It may be that the heating was on in the past causing this.

I have reseated the heatsink and turned on a/c. So far so good.

Does your BIOS/motherboard have CPU temp. reporting ability?

Prester JohnCommented:
BTW a corrupted swapfile points to hardware failure [most likely hard drive].

>>Does your BIOS/motherboard have CPU temp. reporting ability

In BIOS yes, there may be an ASUS tool for in OS reporting, I'll check.

I have not followed on the swap file issue, this was on my list but then I had the heat issue first. I suspect the cleaner may have knocked the PC but it has been stable since I reseated the CPU. I also installed a secondary fan to keep the levels down.

When it failed to boot during POST I checked CPU temp in BIOS and it blew 59C so that is too hot. Will try a new heatsink when I get one...

Prester JohnCommented:
What's your CPU?
Intel or AMD?

btw, PC Probe (ASUS tool for OS info) does not run on W7 for my mobo...

Prester JohnCommented:
59C is not too hot for AMD

AMD's run hotter than Intel's.

What processor is it?


If the ASUS tool runs in Linux you might be able to use a live LINUX CD/DVD to boot from & run it.

yes I thought of that, but then I would still only see CPU temp under Linux load not running all the blob I have installed at the moment...


>>What processor is it?

AM2 5000+

cute, nothing better than a free bit of software, installed HWMonitor...

Cool:

Cores (soz CPU is Athlon X264 5000+) both below 40C
Geforce GPU is at 66C

All others are in the equatorial regions.

great tool thanks. I will monitor this now and see if the PC becomes unstable with temp. If it is stable enough over next week will split this amongst the heatseekers.

thanks

The AMD 5000+ maxes at between 55C - 70C per http://www.cpu-world.com/CPUs/K8/AMD-Athlon%2064%20X2%205000+%20-%20ADA5000IAA5CZ.html

Maybe one of the other utils I suggested will give you a real-time view of the temp?

captainAuthor Commented:
:) Sorry it is not meant to be a habit...

I would not be surprised if a poor heatsink connection had the temp spark up above 65+ when running apps in W7, the temp check at reboot was still high even there was only POST load...

So guess it is now a question of waiting for the next crash..

Points for pointing me in the direction to exclude certain problems.

Thanks for helping, I suspect there is a heat issue. However stress testing has not kicked out the PC but there have also not been any bsods any more.

Baffling...
