net connection rapidly reconnecting

Hi, My internet connection is either spazing out or just hanging and slowing down to nothing. I thought for sure I had malware of some kind messing up my system but I ran all the scans in the malware section, found nothing, and then I was told to repost here for the connection probs
Win 7.

The internet connection started acting very wierd. It kept disconnecting and trying to reconnect, before disconecting again. After rapidly spazing out like this for a few sessions it changed to having a net connection for about a minute and then just almost no internet traffic even though it says it's connected. Or it's connected for a few minutes before the little yellow triangle shows up and says 'no connection'. While trying to fix things out myself with AVG (found nothing) and rebooting/cleaning things out, I had 2 sudden blue screen shut downs.


My PC is connected to a wired router which is connected to another PC were the internet is fine. Also, when I switch the router cable from my PC to my game console the internet is fine. Which make's me think it must be my PC not my ISP. I've also tried unplugging the modem and reconnecting which gets me my internet back for about a minute. But even when I get a connection, It stall before page connection and
durring loading and streaming never connects.


So something is up. Because of the suden change in behaviour and the odd connection spasms (the red X on the net icon going on and off and on and off), I was very surprised it wasn't malware. Any help on what could be going on or how to check if settings have somehow been chaned would be great. Even if we only rule out a software problem without fixing the connection, which is what I suspect.

The symptoms you're describing indicate that your NIC is failing and you may need to replace the card in your computer. I believe an analysis of the memory dumps from the BSODs will confirm my suspicions.

 

@ the OP - analysing minidumps the M$ way is a real pita. You might want to try BlueScreenView as it does take much of the pain away.

 

Do you mean this note I got after the blue screen? I don't know it any of this info is useful or not.

Shut down note:

window has recovered form an uinexpexted shut down.

I just called my ISP in the spring when I had my modem upgraded and we put new username/ password info directly into the new modem itself so that any router or PC connected to it would auto-connect without the connection login box poping up. Would that be a 'reset'?

About contacting my ISP, I have a heart condition, I'm short of breath so to have a long talk with my ISP support would really wind me out. That's sort of what brings me here. I'll call them if we run into a wall but I'd like to try and work out something here first if possible.

This PC wasn't the one I was using when I called my ISP to put new login info into the modem. That XP PC died and I switched to this Win7 PC I had been using prior. It just auto-connected even though I hadn't changed anything since the new modem info.(I'm on disability for my heart condition so I go through these referbished PC's). Sometimes the old connection box pops up and it still has the old username and password and I just close it. There hasn't been a problem with that for the year I've been useing this PC but would clearing this out somehow make a difference? And if so how?
Also, before I delete the card in Device manager I just need to ask, when you say 'take some chances', you mean...'take a guess' right? You don't mean that deleting the card and letting windows re-dect it is risky in any way? Would I need to make a restore point first?

Thanks for any feedback.

 

Yes. Download and run BlueScreenView that Earthling linked to. It will open the file "C:\Windows\Minidump\120813-31215-01.dmp". In the top pane you'll see which driver/device caused the blue screen.

 

These are the two text files I could save from BlueScreenView.
They both have different results though.

 

Another blue screen, titled #3 hapend just a minute ago as I tried to post the first 2 logs bellow...it hung at the blue screen and said:

NMI: Parity Check- Memory Parity Error.
***System Has Halted****

The thing is the results look different for all these files (at least to me) so I don't know if this is a separate problem or if it is related to my connection probs.

@MajorAttitude

I did the re-install of the NIC in the device manager. It didn't seem to make a difference, my connection is still just crawling along for a few minutes before dying. It was listed as the "Intel(R) 82566DM-2 Gigabit Network Connection".

I'd have to open up my PC to double check but...I think I remember opening up this PC a year ago and seeing that there wasn't really an actual network card...just a connector for the cable that went directly into the motherboard.
At this point I'd be fine with just replacing the card to try and get this fixed but I don't know how exactly I would do that. Maybe I wouldn't be able to if it's that integrated.

 

A got another BOD...this time while trying to stream off YouTube, which may confirm it's a NIC thing but...I don't know what these logs mean, if anyone can chime in on that.

Thanks.

 

Certainly network -related, updating the drivers for the NIC is a start.

Some of the dumps refer to file not found or data corrupted in memory, could be an old, 'uninstalled', security software still clinging to your NIC driver or TCP/IP stack, big list of AV uninstallers here: http://www.carrona.org/avuninst.html

 

I updated the driver and got some mixed results, not sure what to think.

At first I thought it was fixed because I got about 5 minutes in, including some songs on youtube before some pages just started to load really slow. But then if I kept trying other sites would load after a short stall. But always now with the loading circle never finishing spinning..

Youtube vids would load up and then in the first few seconds just stop and that red X on the connection icon would start popping up and than disapear and then come back for a few seconds. And downloading files just didn't work it would just get suspended.

So I'm able to get to more pages but am still definitely experiencing alot of the same hangs and disconnections...so sort of an improvement but still not fixed.

So is there any other software solutions? Or things to diagnose?

 

Sorry about the long post, things have blown up in my face...

I have Firefox but I have the same problems when I try Explorer. How would I try and set Firefox back to defaults? If the same thing apllies to a different browser. (I'll update firefox+flash after I've figured out the latest set back below).

But things have gone from better to dead. After updating the NIC drive I still had problems with slow loads, downloading files and streaming BUT I could still get most pages up eventually. I didn't have to keep resetting the modem every 2 minutes. Even if some pages just didn't make it and I knew something was still wrong it was still much improved. But then I changed a setting in Network connections and now it's not connecting at all. Here's what happend:

From your browser suggestion I had gone through the Firefox help pages and was linked to Microsofts help pages were they suggested looking at the Network Connections so see which one was set to the default connection. There was 2 connections: The first one, from before my ISP updated my modem with new connection info, was still set to default even though it wasn't connected which was:

Broadband Connection/ disconnected, Shared/ WAN miniport (PPPOE)

It had the big check mark on it to show it was set to default. The other connection was:

Local Area Connection/ Status cycling between 'unidentified network' to 'no connection' then 'Enabled' / Intel(R) 82566DM-2 gigabit Network connection.

The Local area connection was the one that was connecting because it is connected to the wired router which is connected to the modem. The "broadband" connection hadn't been used at all through this whole thing. I think that one was for when I would plug the cable directly into the PC from the modem, bypassing the route. So I right click on the "Broadband" one and click on "cancel as default connection", right away the connection icon gets the big red X and then the yellow triangle. My browser is completely dead. So I put the default connection BACK on the broadband connection and restart and cycle the PC, router and modem. But it stayed broken.

And now I'm completely cut off. I don't have any idea why that would have made a difference as that connection wasn't even being used. Weirder still I changed it right back and it stayed not connecting. Any idea on how this happend or to get it back to the "barely working" that I at least had before?
