Weird problem with my computer

I am having some issues with my comp, every hour at 7 mins after, my net disconnects me, I have done a virus scan and its some type of timer that was installed, it was fine when I went to bed at 1:30 AM but this morning it started doing it, this isn't the first time, but this is a clean install of win7, if you need my comp specs just ask me, anyone have any ideas of what it can be or whats doing it?, also I don't have many progs installed atm, I have 6 other comps online and they do not disconnect from the net

    It sounds like your anti-virus did not completely remove the infection. I suggest downloading a stand-alone scanner, like the AVG Rescue CD and cleaning your system with it. Download the ISO and burn to CD. Then, boot from the CD, update when asked, and complete a full scan of your system. Remove all it finds.

  2. I'll try that thanks
  3. 0 Found
  4. That is odd. Is anything showing up in your Event Viewer that matches the disconnect times?
  5. Nope, I checked that
  6. Theres a error for NvStreamSvc
  7. But that error started on the 22th, this new prob just started this morning, last time it done this I had malware but this time none of my scans are finding anything, I tried AVG, Malwarebytes and that scan you told me to do
  8. I did a little studying on this issue and detected a small bit of information with my experiece with computers.
    Go to Task Scheduler and view active scheduled tasks. I presume you would find something named along the lines of "netdisconnection"
    I also have a theory as to why it happens 7 minutes after instead of right at the hour.
    When this virus/malicious program was installed, it likely took effect at Hour:07 AM/PM and set itself to go off every hour. You will have to manually end this task first then delete the virus, deleting the virus may not do anything.
  9. Task Scheduler I have, Adobe, AID, At1, ISM-Update twice, all is disabled but At1, that one says, Task at1: The task has properties that are not compatible with previous versions of Windows.
  10. run a scheduled 5m batch script
    netsh wlan connect=SSID
    schedule it to run every 5 minutes with highest priviledes.
  11. run a scheduled 5m batch script
    netsh wlan connect=SSID
    schedule it to run every 5 minutes with highest priviledes.
  12. Compromise! The creator of this discreet virus (assuming it is) is not trying to view your personal information- he just wants to be annoying (troll/hacker). The easiest solution in my eyes is to create a batch file to fix this problem.
    (modify this to meet your ssid)
    :1
    netsh wlan connect=SSID
    goto 1
    Save this as continuewifi.bat, and let it run in the background! This program is continuouly attempting to connect you to the ssid, preventing the virus from disconnecting you for mode than a few seconds. While this is not technically a virus, it is more of a PUP (potentially unwanted Program).
  13. It stopped, hasn't kicked me for 2 hours now, I don't know what the deal is with it
  14. Did you do anything? Or, did it just stop?
  15. stopped for 3 hours then back to disconnecting me, but this time its 21 mins after the hour, I didn't do anything at all
  16. Is this a wired or wireless connection (assuming wireless, but want to make sure)?
  17. Wired
  18. I'v also switched my network cable, I have 6 other comps online, one being my Linux server and it stays connected the whole time
  19. Do you have any unusual processes running in Task Manager?
  20. na, its mostly just Intel stuff

    Try uninstalling the network driver, reboot, it should reinstall automatically. If it is corrupt this will fix it.



    tried that many times
  22. Seems like a reboot fixes it for a little while then it starts doing it again
  23. bobbynow said:
    Ok but did you try removing the network driver completely and letting it reinstall? Go to device manager, right click it and uninstall it, you can then right-click it and hit update and it should reinstall.


    I just tried it again, but windows wouldn't install the drivers so I had to install em
  24. bobbynow said:
    Ok, well see if it works; also check the factory website maybe there is an updated driver. To test if this is a virus, try using a USB WiFi adapter temporarily while unplugging the LAN cable. If the WiFi connection remains stable then it is not a virus.


    atm my only option is to tether to see if that keeps me connected on the hour, so far it hasn't kicked me yet
  25. 20 hours online with no disconnect as of yet, I will post back if it does it again
  26. Its doing it again, this time its 38 mins after the hour every hour
  27. Download the program http://www.wireshark.org/ and use it on your network card. If you get disconnected, you'll see the packet information, it should give you more details on your problem. Be warned, this program will give you information on packets, networks so you gotta have a good background on networking...but taht wont stop you from saving the info it grabs and sending it here.

    in other words, if a packet is responsible for your disconnection, you or someone here will probably see it.
  28. It did it from 3:38 AM to 5:38 AM and then just stopped disconnecting me, this is starting to annoy me
  29. Honestly, it may simply be time for a clean install with current drivers across the board. Painful, but effective. Sorry for your hassles.
  30. yeah that's the sucky part since I just reinstalled windows 7 the other day
  31. Your computer was not able to renew its address from the network (from the DHCP Server) for the Network Card with network address 0x001FBC101482. The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server, that's in Event Viewer but it says 3:09 but also theres 4:09 and 5:09 so that has to be it just timed diff
  32. Understood. I too (and many others) have been down that path as well. It is certainly not pleasant, but it may be the only way to root out the problem you are dealing with.

    BTW. where did you get your Win 7 install media? Via an OEM/retail DVD or via a downloaded ISO? If an ISO, did you get from an official MS source?
  33. OEM, Bought it from newegg.com
  34. Source should be good then. Occasionally, an ISO (when downloaded) gets corrupted and can cause problems. That is why I asked.
  35. if all else fails, I also have a brand new retail that I bought for my other comp but then decided to put Linux on it, I could try it
  36. Instead of getting rid of a (hopefully) nice 400-800$ PC, just get a 40$ WiFi USB Stick and see how that works.
    Does it shut off when connected to ethernet?

    Its on wired when it disconnects, I don't use wireless for my main computer
  38. Hmm....
    Not to sound like a noob but is it the ethernet cable thats the issue?

    I tried a diff cable and a diff port on the router
  41. OK. Is the problem still present?
  42. corcorand82 said:

    No I fixed it, I changed the expire lease time in the router and it stopped disconnecting me, in the router the expire time was every hour, so it was my ISP doing it, just only with my computer, I changed it to expire every 30 days
  43. oh, okay. Good and glad to hear your back online!
