Intel(R) 82579V Gigabit Network Connection - Network link is disconnected. (Event ID: 27 - "ec1cexpress")


I'm new here and I don't usually find myself going to forums and tech websites to find answers to my PC problems but this one has stumped me completely. Short and simple, Friday 13th struck me this year because I've had a ton and a ton of wierd and worrying Event ID's pop up and my PC is going apeshit voodoo on me since. Here's a list of every problem I was getting but the immediate one which I have not been able to solve yet is the described one in the thread title.

What happens?

Well this has been going on for a course of 3 months now and before I never got any kind of event ID for it until I recently hard-reinstalled my Windows 7 for other reasons. I've not refreshed my build in many years and it just needed the fresh start. I thought at first it could have been my ISP. I'm with Virgin Media and I asked the engineer about it when he came out to upgrade my fibre optics plan, he said he had no clue but he will check the connections and all seemed fine from both ends.

Suddenly when I reinstalled my windows 7 the event ID 27: e1cexpress begins appearing all over my logs, occuring more than 30 times a day usually, I never noticed any kind of connection drops until recently and all efforts on google search seem to be in vain. People on there do not have the same rig or motherboard or issue as me, it's something I do not understand or completely straying off-topic to my issue so I had no choice but to come here before I go and buy a new motherboard. I've posted my specs below and what I did before this issue began.

What I did.

Well I reinstalled Windows 7 around June 12th as I said it needed its fresh start after a good three/four years and I was getting a very strange BSOD from time to time which gave me this bug code but it would not allow my PC to generate a crash dump so I could not BlueScreenView it:

The bugcheck was: 0x00000101 (0x0000000000000019, 0x0000000000000000, 0xfffff880009b3180, 0x0000000000000004). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: .

- People say this bugcode points to CPU or power issues with my PC. I find this unlikely given I had to replace my CPU's thermal paste on June 8th due to my temperature in Counter-Strike: Global Offensive being 90-100 degree's and fully freezing my PC. This was an easy fix and after wards I've never had any problems in my games that would point to my GPU or CPU being the problem. I'm really just unsure what this blue screen means.

(This comes from the Event Viewer again, though it isn't the main issue anymore, I couldn't find any kind of solution or clue to what this was either, besides the fact that I had flashed my BIOS once or twice in the past year and foolishly forgot that your BIOS updates do not reset when you install Windows 7 again, so I may of accidentally f*cked my BIOS when I flashed it again around June 12th)

Alongside that on my new windows build, this event ID (Screenshot above) kept appearing. Now the mistake I may of made was not installing my ASUS motherboard drivers from the rev CD that came with my component box. Instead I thought I could just download the most up to date drivers for all my motherboard utilities and features straight from the ASUS website ( Screenshot included showing the downloaded drivers I used instead of my motherboard's CD (because it would of been out of date). I ended up getting into a little bit of a muddle with my drivers but fixed in the end, I'm wondering if may of damaged or did something to my Ethernet driver/component on my MB by making this mistake?

Anyway after that I started getting major 10-20 second Application Hangs which gave me this in the event viewer:

Reset to device, \Device\RaidPort1, was issued.

Event ID: 129

Google said it was something to do with my RAID driver. Earlier that day I did make an attempt to uninstall and completely reinstall all Intel/ASUS drivers I obtained on the current fresh W7 build. I was trying to fix the previous issues, namely the e1cexpress as well, but it looks like I just managed to bog my motherboard and system up even more so I did a second Windows 7 reinstall.

This time on my fresh build of Windows 7 I used the ASUS CD from my motherboard box and put the normal drivers on, only what I needed. So far I wasn't having any problems after I put W7 Service Pack 1 on, Framework 4.5.1, etc. All 300-400 windows updates, Direct-X end-user runtimes, NVIDIA drivers, blah blah the works. Now suddenly this e1cexpress event ID is haunting me again and I am seeing my internet drop for 1-2 seconds literally.

Also another issue among this bible of tech failures I'm writing for you:

An error was detected on device \Device\Harddisk4\DR4 during a paging operation. Source: Disk - Event ID 51

I don't know how to tell which one out of my six hard drives is Harddisk4, but just in case I googled this problem and many people say its unfixable, basically the hard drive is getting ready to die. I backed up all my stuff immediately and started saving money for a new one but I'm unable to identify which one this is. When I reinstalled my Windows 7 for the first time on June 12th (The beginning of this massive tech-babble lol!), I thought it may be handy for you to know that I quick-formatted all of my hard drives apart from my external one I use for backups (I unplugged it during W7 reinstall), then I went into my windows 7 installation and formatted my old C Drive with my old windows on so there was no going back at this point. I was forced to change the partition of my disk to MBR or GPT. I chose MBT and then proceeded to install windows. I don't know if that could of caused a problem or whatever, I just need to know how I can identify which Harddisk #4 is so I know to replace it if it fails.

So yeah it's a ton of problems that have cropped up in the past 4 days guys, sorry if it's a big boring wall of text but right now I seem to have put a hault to -all- issues apart from the e1cexpress ethernet issue. I would appreciate it if anyone could take just a moment to try and help me out, I can't live without my PC lol! especially my internet. It's my life and if you don't believe me? My specifications prove how much I spent on my baby.

In attempt to try and fix this e1cexpress ethernet problem, I just uninstalled my last Intel driver for my Ethernet controller and put the latest one on my PC from the ASUS website.


  • Motherboard: ASUS P9X79 PRO + Realtek Onboard HD Audio
  • Graphics Card: NVIDIA GeForce GTX 780 Titanium (EVGA SC ACX Edition)
  • Processor: Intel Core i7-3820 3.60 GHz / Auto-clocked to 4.60 GHz in games that can make use of the boost.
  • Memory: G.Skill Rip JawZ 16GB Quad Channel (4x4 Modules) - Forgot the speed but I think it is either 1600Mhz or 1800? Definitely below 2000.
  • Peripherals: Razer DeathAdder 2013 (Mouse) / Razer BlackWidow Ultimate 2013 (Keyboard) / Razer Hammerhead In-Ear Headphones / Razer Goliathus Extended Mousemat

    1. I know this sounds unrelated but try it. Set your power settings to always on, i.e. no sleep and no hibernate and no power down anything, and reboot.

      Giving it a try, I'm going for a quick nap but I will be turning off my PC now I just did this. High Performance - No hibernation or sleeps, no power downs, I also looked up something which says it's good to keep the PCI-Express setting on "Off". Screenshot included just now of what I did.

    3. Didn't solve it. I looked on my logs after playing one round of Counter-Strike: Global Offensive, about 6-7 more of the events just cropped up.
    4. Anyone who can aid me here? I'm starting to think I may of bogged my Motherboard by flashing my BIOS like 2 times this year. :/
    5. I presume the NIC connected to a switch or modem? Are you sure it works properly? I've had really weird issues, including system crahes, because of a bad switch.
    6. Well my internet is fine, I can play games, just occasionally my net will cut out for a split second and it can get quite annoying. I'm not getting any crashes or BSOD's because of it. It's just this one Event ID which keeps repeating like 40 times a day. I can't be sure if my NIC is damaged honestly, but I do suspect my ethernet port is faulty because I had my PC over another house for a short time and the friends cable I used had a very very small and tight clip on it making it very difficult to pull out. I'm worried if I may of damaged my NIC by that because these net "drop outs" didn't really happen until shortly after I left my friend's house.
    7. You haven't told us how the PC is connected to the Internet; do you have a single PC and no switch or router? I doubt the connector is damaged; otherwise it probably woudn't work at all.
    8. It's just a single PC with one more in the house that is a relatives. We're hooked upto a Superhub V2 Fibre Optic Router by normal ethernet cables. There's nothing unusual about my setup, it's 100% standard.
    9. I would switch the Ethernet cable to to a different port on the router. You probably already verified it, but does the other PC experience similar LAN issues?
    10. No it doesn't GhislainG, I'm about to get the money to upgrade from a P9X79 Pro to an ASUS RAMPAGE IV Extreme, new MB, new Ethernet, and a very good upgrade all in all. Unless I get the new motherboard in a few days and the problem *STILL* occurs (It would obviously be my internet at that point), no need to keep this topic open but if anyone has any other suggestions that are immediate and could help me fix this problem (provided its software related, not hardware), I'd appreciate it if you helped me save £300. Lol! Thanks again everyone for giving your support, I was sure no one would take 5 mins to care for my issues but goes to show I was wrong, thanks to all again. ☺
    11. Update on the issue! I just had this appear in my Event Viewer log: An error has occurred in initializing the adapter 10. Error Code is 0x490 (Event ID: 50034) Could this have anything to do with my e1cexpress error?
    12. It's difficult to say. How long is the lease defined on your DHCP server? Does it expire within hours or several days?

      I would try a different switch just to make sure it isn't the root cause of that issue.
    13. I don't know what you mean by that GhislainG, how do I answer this? Any instructions you could give? I'm ok on hardware but software I'm nervous at trying new things lol!
    14. Type ipconfig /all from a command prompt. Then check the following lines for your Intel LAN controller:

      Lease Obtained: date and time
      Lease Expires: date and time

      As an example, my IP address was obtained on June 12 at 6:31 AM and it expires on June 24 at 4:55 PM.
    15. Ok I did this.

      Lease Obtained: 16 June 2014 20:17:38
      Lease Expires: 18 June 2014 08:09:32

      Current Time: 17 June 2014 08:51
    16. Best answer
      Then it's the LAN controller or the switch. I had a bad switch that caused a system to crash while other systems didn't seem to be affected; it took me several days to identify the source of that issue.
    17. Yeah so if its the switch (assuming that's a physical part of my motherboard), the MB needs replacing? Buy a new one because I'm about to do that now?

      See all my stuff I buy is onboard, I don't do soundcards, network cards, it's all built into my MB because it's just simple that way lol.
    18. Ok I have a new MB on the way, this topic is closed. Thanks for your help everyone, especially you GislainG.

      I meant Ethernet switch, but you may only have a router.
    20. The solution was the Ethernet cable. For anybody looking to fix this problem.
