Windows 7: Seemingly random BSODs

02 May 2014   #1

Win7 Ultimate, 64bit
Seemingly random BSODs

Getting BSODs at random, but it seems as though most of the time it's because I alt tab into or out of a full screen program. This might of course be confirmation bias.

Got this when I logged back on, maybe it can help:

I thought your problem was solved?

Seemingly random BSODs on new build

Daemon Tools is a known cause of BSODs, uninstall it.

DAEMON Tools Lite	"d:\program files (x86)\daemon tools lite\dtlite.exe"
Let us know how it goes.

My original problem was not solved, however a new kind of BSOD (the full screen one which was later solved thanks to you) appeared when I tried to fix the original BSOD (random BSOD).

Uninstalling Daemon Tools. I will report back when/if I get another BSOD. Do I mark the thread as solved?

Can you also enable driver verifier but only enable the options: Standard settings and IRP logging step 3.
Don't enable Force Pending I/O Requests

Enable Driver Verifier to monitor the drivers.
Driver Verifier -Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

information   Information

Why Driver Verifier:
It puts a stress on the drivers, and so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.

How Can we know that DV is enabled:
It will make the system bit of slow, laggy.

warning   Warning

Before enabling DV, make sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.

If there are no points, make a System Restore Point Manually before enabling DV.

Tip   Tip
  • If you fail to get on the Desktop because of DV, Boot into Advanced Boot Options > Safe mode. Disable DV there. Now boot normally again, and try following the instruction of enabling DV again.
  • If you cannot boot in Safe mode too, do a System Restore to a point you made earlier.

Let us know the results, with the subsequent crash dumps, if any.

Looks like bad RAM to me.

Stress test your CPU with Prime95

I recommend running Prime95 for around 2 hours

warning   Warning

As with most stress tests your component's temperature will rapidly increase.
It is advised that you download a temperature monitoring program like HWmonitor
Keep an eye on your temperatures and stop the tests if it starts to overheat

Stress test your graphics card with Furmark

I recommend running it for around 30 minutes

warning   Warning

Furmark will increase the temperature of your GPU rapidly so keep and eye on your temperatures

Memtest86 will test your RAM

information   Information

Run Memtest86 for at least 8 passes so we get enough information to confirm that your RAM isn't failing

Run a Disk Check to scan for errors

Note   Note

Afterwards go into an Elevated Command Prompt (Run as administrator) and type in sfc /scannow
If it finds errors reboot and run the scan two more times

Run SeaTools to see if your HDD or SSD is failing

Post back the results.
