Random BSOD Windows 7

That would be a final option...as I haven't a clue how to do that at the moment...Have to get my reading specks on.

I scanned and scanned again...including in safe mode and nothing else found....used malwarebytes, superantispyware and MSE.

I've been thinking about when these BSOD 1st started and if my memory is correct....it was after I installed the TV card + drivers. I think windows showed a message when installing the drivers...but I can't remember what....Then had to click an option to start the instillation

So I've removed the drivers and the TV card....now keeping my fingers crossed.

I have just experienced exactly the same problem. KIS 2012 has been installed on a laptop and gradually it has slowed things down. It's a frequent KIS issue and normally solved by a re-install.

Anyway, this time, because I also got a BSOD whilst running a long file duplication search, I decided to give a quick try with MS SE after removing KIS 2012. During a full scan it also found 2 trojans, one of which is exactly the same as yours, the other from the same family!!!

Clearly someone has worked out how to get around KIS 2012. I have cleaned up the laptop and it is now simply whipping along very quickly. As an extra protection I added the realtime version of Malwarebytes Pro. Also for banking I added Trusteer Rapport, free via my bank, which is similar to saferun in KIS.

Everything is now clean, fast and stable!

cavehomme...I've been running MSE/windows firewall for nearly 3 weeks now..without a BSOD. I couldn't make head-nor-tail of the Windows firewall settings...so I downloaded the free version of "Windows 7 firewall control" and its a lot easier to allow/disallow things internet access.

I have also been running regular scans with Malwarebytes (free) without anything being found.

At the time I removed KIS 2012...I also removed my TV card + drivers. If I've time this weekend I'll reinstall the TV card and see how things go.

I also downloaded Sandboxie....now running firefox in a sandbox for another layer of protection.

My PC is also running nicely after the changes...long may it continue.

The MSE / Win Firewall / MWB Pro combo is really smooth and fast. I too considered your firewall option, as well as others, but to be honest I have tried most firewall out there over the years and have come to the conclusion now that if I can't trust what's on my PC then it should not really be on my PC! To avoid malware getting on the PC has to be the main priority and with my current combination I feel quite relaxed. Trusteer Rapport is also running smoothly in the background. I am using Comodo Dragon Browser for general browsing and that has a limited form of sandbox. I tried Sandboxie about a year ago but it was too obtrusive for me, but yes it's a great blocker!

Hope your lack of BSODs continues.

Did you get this PC stable yet?

Hello Tmagic650.

I haven't had a BSOD in the last 4 weeks...Removing KIS 2012 + the tv card seems to have solved the problem. I'll reinstall the tv card soon to see if I remain BSOD free.

Thank for your help.

Tmagic, could've been a software-to-harware conflict, you reckon?

Hard to say... KIS and other programs that disable the Windows Firewall and Windows Defender can cause Windows instability with Vista and Windows 7 now

Haha I've had that experience, which is why I said it. Still, let's hope the guy gets a BSOD free life.

The driver for the TV card is from a company called TBS ...The card is the TBS 8920.
When you install the driver....Windows 7 x64 pops up a message saying something about the driver not being digitally signed...giving you 2 options(this is from memory)....the 1st option is to continue and the 2nd option is to abandon the installation. Maybe this driver caused KIS to act up?

Link for TBS 8920 driver:- http://www.tbsdtv.com/download/

You should always make sure the driver is the latest for the OS you are running. With Windows 7, I have never seen this "not digitally signed" driver problem, although it is common with XP. Are you saying, this is the only driver you can find? It may not be compatible with Windows 7 at all

As far as I can make out, the driver at http://www.tbsdtv.com/download/#tbs8920 is compatible with all recent versions of Windows (with a separate one for Linux).

From what I can tell, it's a x64 (64-bit) driver issue. Win7 x64 needs WHQL drivers, which are digitally signed. Security reasons.
To the OP: There is a way to circumvent this, but I wouldn't recommend it. Troublesome for one, for you have to repeat the procedure at each boot, and second, it's worthless. Just get the latest drivers for your system from the manufacturer's website using the "auto-search drivers for me" feature they usually have.

Hello again.

I have now installed the TV card...with the latest driver from the TBS driver page.
While installing the driver I got the message (image below)...I clicked the 2nd option and the driver appeared to install successfully.
The TV card + Windows media centre are working correctly....So I'll just wait and see if another BSOD occurs.




Thanks again for all help provided.

No yellow exclamation points in the device manager?

No.
No problems so far...I'll update if any problems appear.

MSE has updated to version 4.

Okay, good

Hello

1st BSOD since 24th March 2012.
The TV tuner card was reinstalled on 24th April 2012
At the time of the crash...I was changing channels on Windows Media centre.


Had a look in the event viewer and it reported this problem at the time of crash.
