Varied BSODs, Drivers/Memory

Another memory corruption while Chrome was running.

STOP 0x0000004E: PFN_LIST_CORRUPT
Usual causes: Device driver, ?memory This error is typically caused by a driver passing a bad memory descriptor list. For example, the driver might have called MmUnlockPages twice with the same list.

I was going over your startup programs.

Attachment 304673

There are four items:

You have MSE listed as an AV, please use AVG Remover | avg.com/us-en/utilities to uninstall the AVG secure search. Pick the one that applies to you and run it - 64bit? - . Make sure there is no AVG remaining on your machine. Then test.

If you still have BSOD's:
Steam is a known BSOD creator please use this to remove it: Uninstall Steam: How should I uninstall Steam? Then test.

If you still have BSOD's:
Remove Tenda wireless utility. I looked on their site, but they don't say how to, the best I've found is this: Tenda Wireless LAN Card - Should I Remove It? scroll down a bit to How do I remove Tenda wireless card? Then test.

Do you really need two sidebars?? disable one, then test.

I know I haven't mentioned it yet, but thanks for your immense help so far.

Your welcome.

I removed the wireless utility and attempted to remove whatever bits of AVG I had left. However, I ran the remover twice now, and that secure search thing still remains in my startup programs. Any other ways to remove it?

You could try this procedure: How to remove AVG Toolbar, homepage and Secure Search from your browser If that doesn't do it this should, being its a search tool-bar: AdwCleaner Download

   Note

Please take note of the underlining I did in the second paragraph. Look over each tab after the scan is finished if you miss something especially like a personal home page in any browser listed, you will have to re-set it.

AdwCleaner Usage Instructions:

Using AdwCleaner is very simple. Simply download the program and run it. You will then be presented with a screen that contains a Scan and Clean button. The Scan button will cause AdwCleaner to search your computer for unwanted programs and then display all the files, folders, and registry entries found on your computer that are used by adware programs.

When the scan has finished, look through the scan results and uncheck any entries that you do not wish to remove. When you are satisfied with the selection, simply click on the Clean button, which will cause AdwCleaner to reboot your computer and remove the files and registry entries associated with the various adware that you are removing. On reboot, AdwCleaner will display a log showing the files, folders, and registry entries that were removed.

As for removing Steam, I just won't do that.

Well...That's being pretty cocky, not even for testing? I hope it doesn't come to you making the decision of; Do I want to have a reliable running machine or do I want to suffer periodical game crashes and or BSOD's.

I suggest you brush up on how to tune up your system to run Steam, here I'll get you started, AVG's on the list: Programs Which May Interfere with Steam have you joined their Forum?

It can be helpful to uninstall a program then reinstall it, it can get rid of the detritus a program can accumulate. Yea its a pain but you should boot and reboot between 'stalls even defrag, when was the last time you defraged, do you have it set to auto? Computer Maintenance Guide

AutSamurai said:

Also, looking in my startup programs, I don't see any sidebars at all. Not sure what's going on there.

Could be leftovers, you could check your MSINFO32 and see if they're there. just type that into the Start/Search and click on the first result.

AutSamurai said:

Anyways, I haven't had any blue screens today (so far)!

Great! Do you think you could narrow it down to what might have helped? It would be helpful to other members.

It may have not been the AV. It seems the avg secure search toolbar is a form of foistware see: AVG Secure Search is obviously a kind of malware that attaches itself to FF and AVG "Secure Search" Is Malware - wfredk.com

Okay on sidebars and Steam.

I would give the switching ram to different slots a high probability of why your machine is calming down for you. The windows updates low probability.

Just the removal and install of the sticks cleans the contacts, sometimes you might bend the MB or a stick a certain way, there could be a problem with the slots or the contacts in the slots. Going in there you could of moved something else, could be many reasons, one I haven't heard of in a long while is bad caps, check it out: Badcaps.net - How To Identify

Well, I'll be here if you need more help, but if your machine keeps running okay and your happy with it, come on back and mark your thread solved, it's a flag that tells others that there might be a solution here for them, it does help.

Another memory management issue (0x1a) caused by a Windows Process called Searchindexer: What is SearchIndexer.exe and Why Is It Running?

You can try disabling it in Services and turning it off in Windows Features, but that is only a band-aid and will tend to disrupt other core services of Windows.

At this point I can only suggest two ways to go. I looked back over your thread and didn't see where you ran a SFC scan.

Have you tried to run the SFC scan at least three times or more with restarts in between?

See Note after Option Two step #4:

   Note

• If SFC could not fix something, then run the command again to see if it may be able to the next time. Sometimes it may take running the sfc /scannow command 3 or more times to completely fix everything that it's able to.
• If not, then download and run the 32-bit (x86) or 64-bit (x64) System Update Readiness Tool for your same installed 32-bit or 64-bit Windows 7, restart the PC afterwards, and try the sfc /scannow command again.
• If still not, then you can attempt to run a System Restore using a restore point dated before the bad file occured to fix it. You may need to repeat doing a System Restore until you find a older restore point that may work.
• If still not, then you can use the steps in the TIP box in the OPTION THREE section below to manually replace the files that SFC could not fix.

You may only want to follow the first two bullets.


The second is re-installing Windows. From the time you've started this thread you've already spent a week working on this and like Slartybart said:

Sometimes when battling an issue on a machine, you have to consider the time invested and the time to resolve.

Get all your ducks in a row and do a Clean Install Windows 7

I started up my computer today, to be greeted with a blue screen shortly after startup, and another one shortly after the restart. One of them points to the drivers "nwifi.sys" and "tcpip.sys."

Given that these drivers have things to do with networking, it makes me wonder if something is up with the PCI network card that I use.

Anyways, I'm going to run the SFC scans as suggested in a bit, so I'll return with news from that.

(I hope my issues aren't getting tedious. I know it's been an ordeal.)

Also, these two windows have been simultaneously popping up for the past two days, and the theme switches from Aero to Basic when it happens (although it looks like Aero just magically turned back on a second ago...). Do these have anything to do with the sidebar thing, possibly?


EDIT: Ran 4 SFC scans to no avail, even with downloading the hotfix in the second bullet and restarting the computer in between.

Didn't forget you, I'm not sure of your location but I was doing cleanup from the storm yesterday (020614), I hope Sunday's storm isn't too bad.


Both most recent .dmps point to system files nwifi, and win32k.

Both of those files; nwifi.sys and tcpip.sys. are Windows system files, it could be they don't agree with your network card. You don't list it so I can't help there.

Not a problem, I would believe it's been more of an ordeal for you.

The SFC scans should of corrected that, but you can check the service setting for the desktop manager; go to Run >Type in Services.msc click OK >Scroll to the Desktop Windows Manager Service, it should be set to Automatic.

You don't list SP1 in your System Specs, but it shows as installed in your MSINFO32 report. For more information on Service settings: » Black Viper's Windows 7 Service Pack 1 Service Configurations

Now my computer has started to do something more alarming; occasionally, if I move my mouse/click/etc or after a certain interval of time, my computer lags - as in, the mouse will skip around and the audio will be stuck on a single note, if you know what I mean.

That sounds like a malware infection, but since you're having all these problems with system files, I'd say it's time for either a Repair Install or the more drastic Clean Install Windows 7 if the repair didn't work, and it may not, I'm thinking your HDD has corrupt sectors and you're going to have to format the drive.
