Having problems with your Dell Dimension E521 PC Desktop ?

Internet only works sometimes

\015 I have a Dell Dimension E521. When I first start up my computer everything works fine. After an hour or so on the internet the browser stops responding. I've tried unplugging the modem and resetting it, but that does nothing. Once this happens, no programs will open, alt-ctrl-del doesn't work. I have to pull the plug to turn it off and once it reboots everything works fine again. I have three anti-spam programs, norton 360, Malwarebytes' Anti-Malware, and SuperAntispyware. Non of them can find anything and there updated daily. This happened a while ago so i reinstalled windows, fixed it for a while but the problem is back. I'd format the harddrive but I don't have another computer to do a full format.\015

Answers :

If you are running three virus/malware programs at the same time that could be the problem. take all of them off( uninstall them) and see if that fixes the problem. you can be on the internet for a couple of hrs without any protection as long as you don't surf to many websites

Problems There a are quite a few - sometimes the "shift" key doesn't work. Sometimes the computer makes a loud beep when it doesn't want to load the internet. Most of the time, the only way to get the internet to work is to turn the wireless off and disconect from the network, then turn it back on and tell it to reconnect. The most annoying problem is that at least 1x a week the internet locks up and shuts down, and Word, Power Point, or Excell regurally say "not responding." I've spent the last
