Windows 7: BSODs, maybe Firefox or Flash

13 Jun 2013   #1

Windows 7 Ultimate x64 SP1
BSODs, maybe Firefox or Flash


For the past several months, I have regularly experienced BSODs, between 0 and 5 a day. This is almost always when browsing with Firefox, and might sometimes coincide with Flash activities (like receiving a chat in Gmail).

I have also been getting BSODs when attempting to use FBackup 4.8.286, copying from my C: and E: drives to my G: (external USB) drive.

The only BSOD I managed to grab a picture of contained the following:
STOP: 0x0000000A (0x0000000000261773,0x0000000000000002,0x0000000000000001,0xFFFFF800034B5939)

I very recently updated my video and motherboard drivers, but this did not help.

This is getting pretty annoying. Any help would be appreciated.

Hi Microfrost and welcome to seven forums.

It does not look like your new blue screen dumps were collected. Please follow:

Note   Note
Configure dumps

First, we want to make sure the computer is saving your dump files. Go to Control Panel -> System -> Advanced System Settings -> Startup and Recovery [Settings] Make sure that "Write Debugging Information" is set to Small Memory Dump (256kb) if it is not already.
Dump Files - Configure Windows to Create on BSOD
Next, make sure that the folder C:\Windows\Minidump exists. If not, create it (allow permission if asked). Make sure any dumps you want to analyze, whether yours or others', are in this folder. You can ZIP/RAR the files and send them to someone else to analyze as well.

Start up

Keep less stuff at the start-up. Only anti-virus, this helps avoid driver conflicts and improves time to log in to windows.

Security App

Avast! can often be a cause of BSOD's please remove and replace with Microsoft Security Essentials to see if it provides more stability. Uninstallers (removal tools) for common antivirus software. Microsoft Security Essentials and Malwarebytes are recommended from a strict BSOD perspective. They do not cause blue screens on the system as other AV products do.

Microsoft Security Essentials, Free antivirus for windows and Malwarebytes Anti-Malware Free

information   Information
  • Do not start the free trial of MalwareBytes, unselect that option when prompted.

  • Update and make full scans with both separately.

System Temperature

Ensure that there are no heat issues, For monitoring heat of the system use Speccy or HWMonitor

SFC /scannow to check windows for corruption:

How to Repair Windows 7 System Files with System File Checker
1. Click Start
2. In the search box, type Command Prompt
3. In the list that appears, right-click on cmd.exe and choose Run as administrator
4. In the command window that opens, type
sfc /scannow
and hit enter.


Run Memtest86+ for at least 8-10 passes. It may take up to 20 passes to find problems. Make sure to run it once after the system has been on for a few hours and is warm, and then also run it again when the system has been off for a few hours and is cold.

Note   Note
Pay close attention to part 3 of the tutorial in order to rule the faulty RAM stick out.

Tip   Tip
Do this test overnight.

Thanks for the reply!
  • I have changed back to Small Memory Dump. Sorry, I didn't notice the dates were all old. I have an 828MB memory.dmp file, but even zipped it's still 175MB.
  • I have removed a few old/unneeded startup programs. I know I have a lot, but I do use most of them.
  • I'd like to rule out other issues before ditching Avast!.
  • I have attached screenshots from CrystalDiskInfo. Hopefully they are what you were looking for.
  • It hasn't been too long since I've checked the drives for errors (except the USB since I just got it) but I might give that another go.
  • Temps are OK. I have SpeedFan and CoreTemp monitoring them.
  • I just installed some Windows updates, so I need to reboot, but then I will run SFC.
  • I ran Memtest86+ on all my RAM sticks when they were first installed, but I can try that overnight again soon.

SFC said "Windows Resource Protection found corrupt files and successfully repaired them." I saved the (huge) log file it referred to, and will reboot now.

My system has been a bit more stable, but a couple of times since my last post, I have sat down and found that it had rebooted. I don't have any new minidumps, though, and the event viewer didn't tell me much, just that "The system has rebooted without cleanly shutting down first."

Did you run SFC scannow later? If yes, what were the results?

Can you post a snip of Summary tab of Speccy or HWinfo?

SFC said "Windows Resource Protection found corrupt files and successfully repaired them" and it was after running it that I saw some improvement. No other BSODs that I witnessed, but at least 2 reboots.

If you're looking for voltages and temperatures, see the attachment from SpeedFan. Note: the -12V and -5V rails have never shown the right readings but have been confirmed to be within 10% of spec with a voltmeter.

If you're looking for a list of components, please let me know if you need more than I provided for "My System Specs."

It would seem that your PSU is not putting out the correct volts when booted. It could still show OK on a volt meter, how did you check it? The reading should be with +/- 5%, not 10%.
Go to the hardware section of your BIOS and see what voltages it is reporting, I never have trusted Speed Fan.
