I intalled a new video card, used a duster to blow off some dust and booted up my computer. After I did this I can not connect to the internet. I am able to connect with both my laptop and xbox so I know I should have no problem getting on with my desktop. This is really making me mad because over the last month I have had a string of problems with my desktop and I am really getting tired of them. Anyone help?
 
To answer this kind of question one would need a lot of details about your current situation and your tries. I think it would be better if you post infos such as the type of connection and your tries.
 
Have a cable modem connected to a linksys router. I have tried unplugging everything and it still doesnt work. That is all I have done.
 
Since all other devices are working except your desktop it means the problem is with the desktop. Check all the necessary settings including the ip config and all the stuffs on your desktop. You should make sure that your wireless is working properly. check device manager for confirmation.
 
How do I do IP Config? Just wanted to also note that the desktop is not running wireless its plugged in with an ethernet.
 
check device manager to be sure that the ethernet device is installed for your pc first. to do this go to system properties and click device manager and check under the network sub-category if there is anything like ethernet or lan. Check to see the leds at the back of the card. The ip config is not likely coz you didnt change any software settings. I think.
 
The LED light on the back is lighting up so I know the computer is reading it. Is there anyway I somehow hit a button to turn off the internet. I know on my laptop that if I hit Function F6 it turns off the wireless. Could something like this of happend?
 
ok... firstly... idk what you used to dust the computer... but you should only use an air compressor... or a can of compressed air... and never tip a can of compressed air upside down... it blows ice... secondy... and some variables like if the desktop is wireless or a wired connection will make a difference... i would suggest trying a wired connection first...

1. you need to see if the computer is online... the simplist way to do this if your not to computer savie... would be to click the start button... click all programs, click accessories, and go to the command prompt... you could also click on run from the start menue in xp and type in "cmd" that would get you to the command prompt, or you could just immediatly type "cmd" once you click start in vista or 7 and strike the enter key... once your in the command prompt... to see if your online... type in "ping google "i cant type in a whole url cause i havent made 5 posts but in front of google is www and a period lol and after it is period com" if you get any reply's you've got a browser problem... if you dont, type in once again in the command prompt, "ipconfig" and see if your getting an ip address. if it sais media disconnected... click start, right click on my computer and click manage and then select device manager and see if any drivers are missing... you would see a yellow question mark or exlimation point i cant think of what it actually is right now... i dont useually think when i see it... but anywho... if there is thats a problem... if not, once in device manager click on network adapters and a drop down will show your network adapters... example, your ethernet port (the port where your cat 5... internet cable plugs in, and if applicable a wireless adapter) idk if you have wireless or not... but right click one and click properties and see if its working properly... another thing you could just try if this recently happend... would be to click start, all programs, accessories, system tools, and them system restore to restore the computer back a few days without doing anything techy... but depending on how you dusted the computer i think it could be a hardware issue but in all reality... its hard to walk you threw this without any kind of techy info... sorry :( hope i helped some...
 
I also wanted to say that my computer knows the router is there. It says that it is connected to local only. When I try to direct connect from modem to computer I get nothing. When I connect from moden to laptop it works. This is really annoying.
 
well... i could give an easier way to do this if i knew the operating system but if you read my last post and figure out how to get into the command prompt...

type in a command line "ipconfig/release"
then when it shows all zero's type "ipconfig/renew"

see what happens
 
Working on the IPconfig thing now. I am running on vista home premium. I used a compressed gas duster that I bought at the computer store so that shouldnt be a problem.
 
ok just to try it... click on start... go to all programs, click accessories, click system tools, click system restore and restore the computer back before the problem started and see what happens
 
reply asap cause i'm just sticking around to help you... i'm multi-tasking a bit... getting ready to purchase a wireless adapter for my uncle... looks nice... 300mbps b/g/n ASUS usb wireless adapter with high gain antena for 22 dollars with free shipping... on sale on newegg from 39.99 should do the trick for him... i can even use it as an access point :D

I only have 1 restore date on my comp and its from yesterday so this will not help me. I have NO idea why i dont have more restore points.

i lied just type ipconfig in a command line
then tell me what ipv4 sais next to it

but also do an ipconfig/all and tell me what the default gateway's ip address is
Click to expand...


IPV4= 169.254.50.171

Dont see the gateways IP anywhere. In the one spot is says Default Gateway but there are no numbers next to it.
 
well thats a problem seeing as ur default gateway is your router... what kind of router is it... belkin, linksys, d-link ect. even tho it sais local only its more like limited connectivity... ur not really even connected to the router... it just see's that somethings pluged in the pc... have you tried plugging the modem directly into the desktop... and seriously if u wanna call me we could cover all this in moments...
 
i mean if its a linksys then by default the default gateway is 192.168.1.1 and you could attempt to ping 192.168.1.1 and see if you get a response from your router... other then that... i'm starting to suspect that either the driver is jumbled... the port is shot... or possibly an antivirus software you added or maybe its firewall is messing causing this issue... do you have multiple antivirus softwares on the computer? or have you recently... like in the last 24 hours added any antivirus or other softwares?
 
do you have norton... cause i've seen this happen with that... or did you notice your pc did an update... theres a few command lines we could try... but awnser those 2 questions first...
