Windows 7: Wont connect to internet. Limited or no connectivity

Well I need some help with my hp pavillion p6280t windows 7 professional 64bit. Last week it worked fine and today it wont connect the internet(shows yellow triangle) . Reset the router and still nothing so unplugged the cord and tried it in my laptop and works fine. So went into device manager checked network connectors and they show as enabled and working with no problems. Next I downloaded a hp update for the network onto a flash drive and tried that and still nothing. Im using a verizon router/modem. Everything else has internet and works fine. My ipv4 and 6 say no network access.

May be a system restore may sort it out for you

Well I had to get my mother board replaced a few months ago before my warranty was up and for some reason it never created a restore point.

If you can post a screen shot of your ipconfig/all from the machine with the problem it would be helpful.

I was going to say the same as above. You should try this..
1. Two keys to the left of spacebar is the windows logo hold the windows key and "R" at the same time. When the run menu comes up type in "CMD" once it loads do the following.
2. Type in "ipconfig /release press enter.
3. There after type "ipconfig /renew" press enter.
If your still getting the same message try to powercycle the network (Router/Modem or Gateway) for 5 minutes and plug the modem in then the router or just plug back in your gateway device. Should take care of the issue. If not after the 5 minute powercycle try steps 1-3 again. If your still having issues in CMD type in "ipconfig /all" and list the information here as well as your networking hardware.

Hope this helps.

Well right now im on vacation but ive tried it all. Renewing the ip, static ip address,Resetting the modem,different network card. My computer recognizes that its getting internet(so that tells me that my network card is working just fine) It was just sending out packets and not receiving them but after I did the static ip now its receiving them but not sending them. I have no clue how in one day my computer could go from working to this.

With that said are you running wired or wireless? The networking card that you had changed out was it new or from another computer? Have you tried a factory restore of your routing device? How many devices are connected on your home network? Best bet would be to disable or uninstall the drivers that support your network connections let the computer detect and update them.. If that didnt work out you should find your hardware drivers online and reinstall them.

Im running a wired connection
It was a new card. Tried 2 actually. a wireless one and another Ethernet one.
I've reset my router a bunch of times
On my network im running 2 wireless laptops,tv,wii and ps3, 2 wired connections are my desktop(the one im trying to fix) and our office computer.
I've tried updating my drivers and it hasnt helped.
