Windows 7: Random PC freezes 2

Random PC freezes 2

Hey there. It's been a year since i visited this page. Unluckily i need your help again.
I am having some problems with my pc recently. What happens is that while i am using my pc it sometimes freezes and nothing responds so i have to manually restart it. It happens 2-3 times everyday and it has happened while i was doing random things, like using google chrome, firefox, skype.

I have posted the zip file with the results of the diagnostic tool. By the way i had the error stated in the faq
SF Diagnostic Tool - Using for Troubleshooting
and i runed the diagnostic tools one by one and the error came up at minidump.

I had experienced the same freezes about one year ago. Here is the link of my old thread Random PC freezes . (have a look at pages 1-9, pages 9-12 are related to another problem that occured, different to the one i have right now).

After many tests and posts we found out that the problem was related to my gpu. I sent my pc to the store i bought it and they told me that the gpu was destroyed due to a voltage drop. So i bought a new gpu and everything was ok until now. The thing is that i have bought a ups since then.. so any voltage drops can't harm my pc now i guess. So i don't believe the problem is related to my gpu this time.


Hope we find a solution. Thanks in advance.

There are no dump files in your upload, you can manually check C:\windows\minidump to see if any are there

In that folder there are only dumps that were created last year. There aren't any new ones. Is there any other way i can create minidumps?

No they are only generated during a crash
You could try enabling driver verifier to stress out the system drivers which may create a crash but only if the root cause of your problem is driver related
Using Driver Verifier to identify issues with Drivers
Or you could try running a stress test to work the machine a bit but if you do i would advise you monitor temps during the test and dont leave unattended

The last 2 days i did the tests you told me to.

I tested the driver verifier for about 42 hours continiously and my pc was kinda laggy but no freeze or crash happened. Before the test i usually had a freeze every 2-4 hours.

I also did 2 stress tests with Prime95. I runned the Small FFTs first for about 2 hours and then the Blend test for about two hours. Both of them passed and no crash or freeze happened.

Ok thats kinda good and bad news i suppose
Machine lagging is normal and expected, its just the result of verifier running

Not sure the best way to proceed, if you want to be proactive you could run more hardware tests or just wait to see how it develops

For the last 4 days i didn't have any freeze and my pc seems stable. I did the stress test with furmark and in 4 minutes it reached 98 oC so i stoped it.

The freezes happened after i updated my nvidia gpu drivers. But after i reinstalled them the problem wasn't fixed.

Nevermind.. i am marking this thread as solved. In case of a new freeze i will inform you =P
Thanks for the help

Hallo there again. It seems the problem wasn't fixed. So yesterday and today i had freezes again. What also happend 2 other times is this. I experienced some ''mini-freezes''. By that i mean that my pc was freezing every 1-3 minutes for about 6-7 seconds. I waited to see if it would stop but it wouldn't so i restarted it.

So any ideas? Should i try and do the tests you told me to in your previous reply?

Personally i would try rolling back the gfx driver to a good stable release (306.97)

Hardware tests listed above are an option but what about that gpu temperature from before that is kinda worrying have you cleaned lately ?

Could also try Troubleshoot Application Conflicts by Performing a Clean Startup this may be applicable/useful to your situation
