Why did my laptop BSOD?

Had posted this in another thread, but it had become confusing, so to make it a more direction question, can anyone see why my laptop has been crashing lately?

It happens after its been left on for a while (>1 hour), but doesn't need to be doing anything for it to happen - once happened on the Win 7 Login screen!

I've attached these files so that someone can take a look, hopefully.


Its an Acer Aspire 7520 running 64bit Windows 7.
Upgrades: 2x2Gb matched pair RAM & a 2nd HDD.
I've checked temps, and they are fine (as discussed in another thread).
Idle CPU 45C, GPU 65C
I've also totally removed any dust from the inside of the system using compressed air and replaced the standard thermal paste with Artic Silver 5, although the heatpad on the chipset(GPU) couldn't be replaced this way.


Happy to answer any questions on my setup etc.

TIA

 

Are you running RM clock?
It happens to me when I leave for a while in idle mode with RMClock active...

But as soon as I disable/turn off RMClock BSOD is not happening...

However I did some testing and managed to solve the issue with RMClock...

 

Never heard of RM clock, so fairly sure I can say no to that one

Also, its happened a fair few times, only once when idling.

 

Hi, thanks for the reply.

1 - I don't know what you mean by plain text files. Those zips have some file format that I can't read. I'm hoping someone can interogate them and tell me what's going on

2 - I had installed new drivers, from NVidea about 3 weeks ago - about a week later this started to happen. I suspected the drivers could have been the issue, so I rolled back - the issue still happened after this.
Also, I had Windows update turned off for a long time - I only started applying updates in the last month or so.


As for the last point, no, I never do that. I've never used any ghost-type software as I've never felt the need. A OS re-install takes me very little time, and I can do the setup remotely from work using logmein. Its a welcome distraction from work!

 

did you overclock your CPU or GPU ???

I think since you say that you don't know what RMclock is ... that means you didn't undervolt the CPU or am I mistaken and you maybe undervolted your CPU using another software ?

 

No overlocking.

Never heard of undervolting before I started reading these boards a couple of weeks ago.

 

Bump

Can anyone view and diagnose these dump files?

 

Take out one of your memory chips. Test.
If that works. Take that one out and put the other one in, Test.

Unexplained BSODs often lead back to memory issues, IMO, and you did upgrade...

Your dmp files are binary. Sorry, I'm not messing with them

 

I ran Memtest overnight and got no errors.

I upgraded the RAM the first day I had the laptop, about 2 years ago.


Considering it hasn't crashed for over a week (it crashed about 6 times in all), I can't really take one RAM chip out and see if it "fixes" anything.


Just need someone to read and interpret the dump files, I know it can be done, otherwise why are they produced!

 

Bump. Can anyone read the dmp files?

 

Did you try posting your dump file on the official Windows 7 forum?
I did some googling and found that BSOD with BCC code 124 means a hardware failure...
If you remember I also mentioned that I had BSOD with BCC code 124 very often lately... I was trying to solve it and few days after those very often BSODs Windows bumped me a message that my hard drive is failing and that I should replace it... I did a SMART check and there was quite large number of bad sectors... Since I replaced my HDD I am not getting BSOD... And it was a few days ago since I replace HDD... But till then I had at least one BSOD a day average, sometimes up to four or five...

Till now I got rid BSOD - finally thank God...

Hope this will be useful...

Cheers
