So I went to my event viewer, and this is what it says whenever it's happened the last couple of times:
Name resolution for the name dns.msftncsi.com timed out after none of the configured DNS servers responded.
The client was unable to validate the following as active DNS server(s) that can service this client. The server(s) may be temporarily unavailable, or may be incorrectly configured. 68.94.156.1
And I went back through older logs of when the same thing would happen, and those two were the ones that popped up the most. However, this also popped up from time to time:
Name resolution for the name www.microsoft.com timed out after none of the configured DNS servers responded.
Name resolution for the name www.australian-charts.com timed out after none of the configured DNS servers responded.
Now, I know my way around a computer, but this internet talk is pure "gibberish" to me, for lack of a better word.
Additional information: The connection to my router is wired, not wireless. My PS3 and my laptop can stay connected/have never dropped a connection, while my desktop does it enough that it's beginning to bother me.

I posted here a few days ago about some programs not recognizing there was a connection to the internet, and it turned out to be a problem with my DNS servers. It was fixed and everything was working fine until last night when the problem returned. I did an ipconfig /all and it looks exactly the same as it did after I fixed the problem, showing that I'm using google's DNS. This is the current ipconfig /all
Code: Windows IP Configuration
Host Name . . . . . . . . . . . . : Matthew-PC

I have a USB 3.0 that keeps dropping the connection to the devices I try connect to. For example it recognizes my external HDD but then drops it second later. Then it flashes on and off in being recognized. With my wireless keyboard it doesn't recognize it at all.

My friend just re-bought a computer, and it's not recognizing his Ethernet connection. There are no unknown devices (Other Devices), there is no "Network Adapter" list in Device Manager. The LED lights up in the back of the system, but the computer is not recognizing it. The cable is not faulty, and is currently working.

I have a 6 month old computer with Windows 7 on it. Anyhow, I always use iTunes and backup/load songs from it to my iPhone 4 and 2nd gen iPod.About a week ago is when I last was able to connect my iPod to itunes and load new songs. However now my computer no longer recognizes my iPod. I thought it was iTunes at fault but my computer still recognizes my iPhone no problem (with the same cord) and my computer also recognizes my gps watch with its own separate cord.I've tried restarting my computer, unplugging it, using both USB ports but to no avail.The ipod charges when plugged in to the computer but it just isn't being recognized (there are no removable storage devices showing in my computer either).I opened device manager and it shows 2x Generic USB Hub, 2x Intel 6 Series...Hos Controller, 2x USB Root Hub, 1x USB Mass Storage Device. When I go to properties > details > hardware ids of the USB Mass Storage Device it shows USBVID_0BDA&PID_158 and also USBVID_0BDA&PID_158&REV_5888.

I'm using an Asus P9x79 Deluxe with the antenna that came with the mobo, along with Windows 7. I normally have the computer plugged into an ethernet channel, but today I moved it into a different room for work and it cannot connect wirelessly to the internet. In fact, it does not give me that as an option at all! Strange, as I never had this problem before.The only significant change that I had was I installed Adobe Creative Cloud, but I don't see how that could mess things up.

I have an HP Pavilion Elite HPE machine, Windows 7, Radeon HD 5700 Series graphics card, connected to an Acer monitor and HDTV. Here's details on my setup:
My Equipment | Building a Home Theater With Your Office PC
My problem is that even though my HDMI cable's plugged into my Radeon graphics card, sometimes the PC only recognizes the Acer monitor and not the receiver (that's connected to the HDMI cable and my HDTV). So I end up having to plug and unplug the HDMI cable several times (sometimes 10+) before it recognizes the HDTV/receiver connection. Is there any setting that would favor the card/PC recognizing the HDMI cable more frequently? I've heard it's a handshake issue, and that maybe using a different type of cable would work. But wondering if there's a setting I could use before switching out cables.

I have an Asus X58 motherboard, a pair of ATI 5850 video cards, and a pair of monitors running DVI into the primary 5850 (extended desktop). When I am not running crossfire, my device manager sees 2 5850 cards as does the catalyst control center. I can select "enable crossfire" from the control center; however, when I did that my computer became unresponsive and I had to reboot. When I reboot the computer and click on the performance tab of the catalyst control center, the only option is "AMD Overdrive", the crossfire option is no longer there. The device manager only sees one card. The only way I can get my computer to recognize both cards again is to remove the Xfire cable from the 2 video cards.

I have the wireless adapter working fine, well it was working fine. The strength of the connection was only 2 bars for some reason as of late. I have other computers and they're all fine. So I assume maybe I can fix it by installing the drivers for it. The moment I install it the computer stops recognizing that I even have the wireless card hooked into my mother board! Did the driver installation break it? Because even it when it was supposedly done installing it claimed that I needed to actually plug the thing in! Even though it was working fine a minute ago. I've tried running the program but it wont even acknowledge my clicking. I tried unplugging and plugging the hardware in and that didn't work, I even changed its slots. I don't know what to do short of just reloading windows on it and skipping every using the driver cd.

Such as a mouse, a mobile, or an external drive.I mean make them visible (in My Computer) even though they're not connected so it's easier to remember what devices I use. My memory is awful, don't ask.Obviously I know I wouldn't be able to access the files unless the devices were connected, but the point is to make their icons show up as if they were connected even though they won't actually be of any use.

I've just bought a new computer and put it all together, installed drivers etc but no sound is working.If I go to Control PanelHardware and Sound it says "no audio devices are installed".However, if I go to Device Manager, under "Sound, video and games controllers" there are 4 instances of "NVIDIA High Definition Audio"Now I guess thie Nvidia drivers might work through the HDMI connection on the GPU, but my soiund setup is with the old audio jacks that plug in to the back of the motherboard.I tried uninstalling the nvidia audio drivers in device manager but when I rebooted they just installed themselves automatically!

When streaming Netflix, my computer is registering as a new device each time I play a movie. The Device ID is different when I check on all my registered devices (the only device that uses my account is my one computer). I have not changed any settings, reinstalled Windows, or made any drastic changes in the system. I do not use a router and am using Cox Communications as my ISP.

I have been unable to connect to anything on my wired network, for about the last week. I don't remember making any changes however, I just became unable to connect.I having done a little troubleshooting.1. I can connect to the shares of my Windows Home Server if I use the IP address. The name does not resolve.2. Flushed DNS and restarting DNS server. Flushing DNS works on one client, to allow browsing by the name & restarting DNS works on the other. However neither works after a restart.3. Only my Wifi clients are experiencing this issue. My wired clients, desktops, PS3, Xbox 360, and Boxee can connect perfectly.This issue is not limited to my server. I can't connect to shares on my desktop, nor print to my wired printer.Some network background:I have DSL through CenturyLink and have a Linksys E2000 router.

you have all your computers connected wireless to the internet. You should be able to send from computer to computer through wireless connection also.

I've been having this problem since I bought this new computer a few weeks ago. It's a HP desktop, the model number is s5229uk and it's Windows 7 Home Premium.
At random times when I'm browsing the internet, sometimes it can be every 10/15 minutes, sometimes just a few times a day it will stop loading and a yellow triangle with an exclamation mark will appear on the connection icon in the bottom right hand corner.
I cannot troubleshoot the problems or open up the network and sharing centre because it either doesn't load at all or freezes, and the only way to reconnect is to hold down the power button as shutting down or restarting fails after about 20 minutes of the shutting down screen.
It's more annoying than anything. I've checked for viruses but nothing came up and the one time it's let me troubleshoot, it's told me to reset the router which I did and it didn't work. I thought it might be a compatibility issue with the router (we use Sky) but some days it works for longer than others.
On the Norton internet history for firewalls and connections I found this which I think might have something to do with it. Does anyone have any ideas how to stop the internet from cutting off because me and my Dad are at a loss, and he's quite good at computers.
Another thing is that it won't let me create a system image by backing it up onto an external hard drive, it gets to a certain point and gives me this message: 'The system cannot find the file specified. (0x80070002) I've tried again and it still doesn't work.
