Windows 7: BSOD on restart, boot and during Skype video call

BSOD on restart, boot and during Skype video call

Hi

I've had 3 BSODs since the end of January - 2 of them yesterday. The first happened during restart after the system became unstable and would not load any Firefox pages or allow me to close it or stop any processes. I wasn't in the room at the time.

The second happened on boot and whilst I was out of the room, so not sure how far it got before happening.

The third happened a couple of minutes into a video Skype call yesterday. After reboot I was able to resume the Skype call, (although with just video on my side of the call (not receiving video) - we didn't try video on both sides)

System Details:

Model: Dell XPS L702x
OS: Windows 7 Home Premium 64 bit
Processor: Intel Core i5-2410M CPU @ 2.30GHz
Memory : 6GB (1X4GB + 1X2GB) 1333MHz DDR3 Dual Channel
Hard Drive : 500GB Serial ATA (7200RPM)

Windows 7 x64, originally installed on the system, OEM.
System is about 10 months old and so is the OS (no reinstall)

The laptop is always hooked up to a Samsung SyncMaster B2230 external monitor and a Buffalo Ministation external drive.

The first BSOD happened a day after allowing a McAfee technician to remotely reinstall McAfee Internet Security and 4 days after installing Photoshop CS5.

I don't know whether this is related or not, but I regularly get a problem where there is a time-lag when I am typing or before I can click on a Firefox link (though this may be Firefox). There's also a problem with McAfee intermittently using up to 84% of the CPU, so I dunno if that has something to do with it...

I've also had a few system freezes accompanied by a rhythmic squeak that sounded like it could be coming from the hard drive. IIRC there was one BSOD that happened during one of these times, though I don't think the dump file for that one is available. This hasn't happened for a few months and seemed to happen when playing music via Windows Media Player. I ran chkdsk and it didn't find any problems.

Any help would be gratefully received because I don't have a clue to fix this

Hi.


Remove Mcafee from your system.



Download and install Microsoft Security Essentials with windows firewall enable.



For your system protection you can also use this Good and Free system security combination.




Finish with the above steps and post back with results\news.

Hi

I'm a bit worried about removing McAfee and relying on MS Security Essentials / Malwarebytes A user review on CNET states:

Quote:
became infected with severe threat Troj JS/Blacole Ref.D. within hours of installing MS S.E This despite also having Malwarebytes Pro, G. Chrome 17 (fresh) all browser, definitions, updates current same day. This program does not prevent infection but only prompts user to take counter-measures (active removal). This was the first "severe threat" to infect my computer in 12 years. Make sure that you understand the default settings and change them.
Do you really think that removing McAfee would stop the BSODs and other issues? McAfee regularly stops risky skype connections too, so don't want to lose that protection.

I realise that you've probably know more about this stuff than me and I know that McAfee might be causing me problems, but wouldn't another commercial Firewall / Antivirus(maybe Webroot?) be a better option?

You must don't rely in cnet or in any websites general "talking"


Mcafee cause you troubles.



Mcafee gave you BSOD.



Remove Mcafee from your system.



Read and use this Good and Free system security combination.



You can use whatever you like,but don use (especially) these Mcafee,zonealarm.

Would you mind explaining to me how I know for sure that McAfee gave me the BSOD?

Thanks for the link to the free security thread It seems that the free versions of Malwarebtes and SuperAntiSpyware don't offer real-time protection, so I'd be relying on Microsoft Security Essentials for this and it seems from the CNET user that it's not too great at that.

Please could you give me some idea of the percentage of threats that your security suggestion would protect me from?

Also would MS Security Essentials firewall block risky skype connections?

Thanks

Ok,lets try for one more time

This is a sample from one of your minidump analysis, mfehidk.sys is Mcafee.

As you can see mfehidk.sys is the source of the crash\bsod.

Code:
se !analyze -v to get detailed debugging information.

BugCheck C2, {7, 109b, 10f2c000, fffffa80054b1b7f}

For now dont bother with "external" opinions\reviews.


Now you are here in sevenforums so please lets co-op to find a solution to your problem.


I am trying to help you.


Remove Mcafee from your system.


Download and install Microsoft Security Essentials

Windows 7 has firewall so keep it enable.


Follow this instructions Good and Free system security combination.
including the "enable the Router firewall" part.

None\nothing in the world can protect you 100%.


You can protect 90% yourself\system by avoiding "bad" places and bad system usage.

Thanks for explaining - it's good to know exactly what happened

I'll trust you and do as you suggest, but I need help with making sure my router firewall is enabled. It's a Billion BiPAC 7800N and the user manual is dreadful. Do I need to turn on "Intrusion Detection" for the firewall to be on? It's not obvious

Thanks

Dont enable Intrusion Detection System (IDS).

Keep IDS off.

Just enable the firewall.


Read aaaallll this Good and Free system security combination.


The first lines that i have there are,


Starting from "outside" enable the Router firewall.
Go to...Start\Control Panel\Network and Sharing Center,click the House/Home Icon first to be able to see the router icon,right click on the router icon and click View device webpage,find the firewall\configure,select standard,Apply and exit.


Another way to get there is by typing the router IP address in your web browser.

To find your router ip,click start,accessories,click on Command Prompt,write in Command Prompt "ipconfig" without the quotes and press enter (View attachment D).

I understand how to get to the control panel, but the firewall options aren't easy to understand. As far as I can tell the firewall is off until you enable specific rules yourself. See the attached image for the main page I get when I select Firewall.

These are the advanced settings. Basic settings give no firewall options at all...

I can read through your manual and figure it out, but you might get instant or at least faster help if you start a new thread in Network & Sharing - Windows 7 Forums since the experts in there have far more experience with these configurations.
