Windows 7: Random BSODs when on wireless network

Hi - Yeah, I've been using System Suite for years. I did run their malware day before yesterday as part of my search for problems.

Edited to add: I just BSODed while I was in Safe mode. First time that's happened. My on-line speed goes down after the BSODs too. From 25-30mbps to 5-10.

Yeah, I was afraid of that. I know people have the choice of what they want to use but when I see "tune up" and "repair" on programs I already know they do neither.

Can you download and run a scan with the free Malwarebytes,

Just untick the option for the trial premium.

Are you using a VPN software? One of your earlier dumps was pointing to that.

Got another blue screen last night so I turned the thing off and went to bed!

I ran malwarebytes this morning and it did find assorted adware/browser hijackers, etc or remnants of them... 126 items, and I told it to quarantine everything. I doubt if any of these is the culprit, but it can't hurt to have them gone. I was surprised at how much stuff there was. Did you want to see the log from that?

I don't use a lot of the stuff on SystemSuite, but it has been a good anti-virus and firewall for me, and I will occasionally run their defrag or other clean-up tools. I've used it for years, so I'm used to the interface....

I do have a VPN that I log into 2x a week, working remotely from home. Oddly enough, I have not had a blue screen while I've been on the VPN. Could just be coincidence, since the crashes are so random.

Several more bsod's today since running the malware scan/clean, and a new one:

PFN_LIST_CORRUPT Stop: 0x0000004E

Ran chkdsk after that and it didn't find any problems.

Sure, you can upload the log from the Malwarebytes scan. I am curious to see what it found. That's a good tool to keep on your system.

Can you run the tool again, so I can look at the dumps and other info.

Hi derekimo, Thanks for hanging in here with me!

I'm getting more bsod's today, and got another new one just now, with a new driver named: fltmgr.sys

I've been online quite a lot today, so that's probably why so many.... I am getting concerned that I may be causing additional damage to my system by continuing to re-boot in normal mode after a bsod. What do you think about that?

I've uploaded the latest dm log for you, but it's not loading all the files again - I tried it 3 times and this is the best I can get. I don't know why all the files aren't loading into the report... when it's running, it appears to be doing everything it's supposed to.

I'm keeping my fingers crossed that it shows something helpful....

Hi there,

You're welcome. That driver is a Microsoft driver, that's not the real cause. Do me a favor and empty out the C:\Windows\Minidump folder, it's just getting packed with older ones you've already uploaded.

Just looking at the ones from today, I see a couple that blame your VPN software driver,

BugCheck 19, {20, fffffa800aaa2920, fffffa800aaa2a00, 40e004a}

*** WARNING: Unable to verify timestamp for dnelwf64.sys

Driver Reference Table - dnelwf64.sys

Can you see if there's an update for that.

I suggest you delete the quarantined items Malwarebytes found.

A couple others were the Athrx driver, and some assorted bugchecks.

When the dumps are all over the place like that, it's a good idea to test the hardware, since I saw a storage driver in one of your earlier dumps, checking the hard drive is a good start.

Please perform the following tests,

chkdsk /r

Okay - I ran it again and saved the folder file and zipped it myself (instead of letting DM Log zip it), and this one has all the files you need, including the msinfo.

Edited to add - Whoops! I didn't see your post above before I posted this. This one does still have some of the older minidumps...

Will do the items you list above, and report back.

Thanks again for your help!

Deleted the malware-found stuff, and ran chkdsk /r and it didn't find anything. I'll run the Seatools tonight and see if it finds anything. Thanks for the link.

For that dnelwf64.sys issue, I'm going to have to submit a ticket to IT at work, as it's their VPN I'm using. I'll link to this thread. Maybe they'll have an idea of what's going on, or a driver update for me.

In the meantime, I'm staying on an ethernet connection so I won't crash any more.

Another thing that has started happening is that it takes forever for certain folder to load, like my default Downloads folder, or Control Panel/Programs.

I'll see what they have to say tomorrow, and then post again.

Well, Seatools didn't find anything, and I didn't have time to submit a ticket to IT at work today, but someone else in the office who remotes in tells me she's been getting bsod's lately whenever she tries to launch the vpn.... So I'll be sure to submit a ticket tomorrow and see what they say.

Thanks again....
