I've been having constant BSOD for a long time. It usually happens when I'm gaming or watching videos. Also, going fullscreen on games and videos triggers this BSOD sometimes. Sometimes, it doesn't even blue screen. It just completely freezes with the audio freezing as well. Sometimes, it'll create white vertical lines across the screen with the audio freezing. I researched this particular BSOD and it said it has to do with the Memory. So I tried MemTest86+. After 6 passes, it found 0 errors. I heard sometimes even MemTest86+ can't detect it all. I took out each RAM card and TESTED each by itself and it still blue screens. Not sure what is causing this. I used BlueScreenView to get this dump. There would be more but my cleaner removed the dump files. But this BSOD just happened so I have this dump (Ignore the time. It's incorrect.):

==================================================If you don't currently have the latest release of Avast, please download and install it now. If you do, I suggest uninstalling Avast and installing a different anti virus app.I have the latest version of Avast! Internet Security. These blue screens have been going on even before I installed Avast. I used to have AVG and this would still happen. I know it's not a virus because after a fresh format (full), this still would happen. I'm currently uninstalling Avast to make sure. Just before I read your post I had another BSOD. Each time I blue screen, the driver cause changes. I'm not sure if that matters.

==================================================Hi ug505,

Looking at the 3 reports that you have uploaded, the issues are pointing to multiple DRIVERS which I don't believe are the issue. (one of them points to the mouse driver) Your BSoD's are triggered when gaming or watching videos which would lead me into thinking that the issue is more than likely to be related to you GFX card. I can see that you have already run MemTest86+ which is good. (hopefully you ran it on each stick individually, using one slot at a time to rule out a bad slot)

Have you tried physically removing your GFX card which would make your system use your onboard GFX instead. I know that this will impact your gaming performance, especially if your onboard GFX are not that great, but it is a good way to try and rule out the GFX card being at fault (I also take it that you are using the most upto date drivers for your card?)

Also, if you have any overclocking on your machine, disable that too. Another cause of BSoD's can be the use of Daemon Tools (programs that allow you to VIRTUALLY mount ISO's) like Alcohol 52%, PowerISO etc, so try removing those as well.

Have you run a System File Check? (SFC) Open up a command prompt at an elevated level. Start>All Programs>Accessories. Right-click on Command Prompt and choose Run as Administrator. You now have the choice to either verify that your system files are OK, or you can get Windows to check and repair for any problems. (should it find any issues) For Windows 7 this won't require the installation disk, and can take a while (10 mins to 1hr depending on your specs) to complete.

To verify only that your system files are OK, simply type sfc /verifyonly and hit enter. (This won't make any changes to your system files, but only checks for issues)
To check and repair and issues found, then instead type sfc /scannow and hit enter. (This will make the necessary changes to your system files)

If you choose the first option (to verify only) let us know what problems it may have found, and if there are any issues that it can't resolve.

Note: I'd look at the GFX card first though, as that looks like where your issue is coming from, due to the description you gave.First of all, I don't see anything related to the mouse driver. The first bsod points to aswSP.SYS which is an Avast file. The second points to stream.sys which is a system file related to, well, streaming.

1) Please do a search for stream.sys and post its location

2) What is new or different since the last time everything worked properly (ie, new hw, new sw, virus, error, etc)? Have you recently updated any drivers?

3) Look in Device Manager - any yellow or red symbols?Additionally, the machine is a laptop, the 3870X2 cannot be removed. If it was a desktop and had onboard graphics, that would however have been a good suggestion and my first port of call, I suspect the graphics card is on its way out although that's only a preliminary suspicion.Hi Allan,

The first one pointed to mouclass.sys which is a mouse driver. The second report pointed to aswSP.SYS which is the Avast! system protection driver and the third report pointed to the stream.sys which is a Stream Class Driver possibly relating to a webcam.
It just seemed strange that each report was pointing to various issues, and nothing specific which is why I asked him/her to run SFC (pref verify at first) to check for issues.
Agreed that I should have asked OP to check for driver related warnings via Device Manager though.

[Edit] Just saw the reply regarding it being as laptop. Sorry I assumed desktop. A full system spec would also help. OP can use Speccy ( http://www.piriform.com/speccy ) to do this by running the program and then going File>Publish Snapshot, which will present you with a URL that OP can post here, that will alllow people helping to get a better picture of the machines specs and current updates/ temps etc. It's best to use the Publish Snapshot as this won't include any personal info like the various serial numbers, unlike just uploading a spec report via text file.Quote from: TheGift73 on JUNE 27, 2013, 06:58:00 AM

Hi Allan,

The first one pointed to mouclass.sys which is a mouse driver.
