BSOD Windows 7 64 bit

I have been getting many BSOD's recently. They started about 2 months ago and have been getting more frequent as time goes on. I have already had 3 today alone! I have attached a crash report. What is causing these? And how can they be fixed?

(I have Windows 7 64 bit)

Thanks

 

The actual dump would be more helpful, but I would start with looking at video and sound drivers. Have they been updated? The fact that it seems to point at ntoskrnl.exe isn't really helpful, though that could be a strict memory issue.

What are you doing when it occurs? Is there a way you can reproduce it, or is it completely random?

 

Also this program may be of use Blue screen of death (STOP error) information in dump files.
the program is 3/4 of the way down the page, it is a zip file. No install needed.

 

@OP see this link:
"ntoskrnl.exe" BSOD - Windows 7 Forums

And, dump files are helpful, but it appears to be related to this.^^

 

Here are the 4 most recent dump files.

081211-32011-01.dmp
081211-36894-01.dmp
081211-37221-01.dmp
081311-35693-01.dmp

It's random.

Thanks, but I have already installed that program.

 

First thing I would do is run Memtest86+ for a few hours (for ex. during the night) to exclude bad RAM as a cause! Bad memory is very likely to be causing BSODs.

Then, I would look into any recently installed software. I have had BSODs caused by ZoneAlarm - stopped using it and never had another!

Last thing to do is reinstall the system from scratch and keep it as clean as possible for 2-3 days to see if this has cured the problem. If yes - go ahead and carefully install all your software. If no - you can call for service pick up as obviously it is a hardware issue and not the memory....

 

Ran an analysis on the four dumps and they are inclusive.

I would run verifier from the start menu

Start>
type
verifier.exe
in the search box and hit enter

Just leave the defaults and click through until it gives you results.

If nothing shows as unverified, I would follow Gracy's lead by opening the back and removing one stick of ram and run things for a while. If the computer crashes continue, switch the removed stick with the other stick.

See if that clears things up

 

I have found the program causing the BSOD's - Advanced System Care -specifically when it tries to remove 'junk files'. This explains why windows appeared to crash randomly - the program is set to automatically clean the system when the CPU is idle.

 

Glad you found the reason!!

I would stay away from such "take care" programs. All you need is a good defragmenting software. Removed Vaio Care on mine as well - it was only slowing the system down.
