Have an XP home laptop less than 1 month old. 1Ghz processor with 1GB memory. Only installs are adobe reader, zune and malware bytes. Increasing difficulty in navigating the internet and after OS updates today, I find "cannot display webpage" on all URLs. The diagnose option demonstrates "no problems" but still cannot navigate to the internet websites. Task manager routinely shows about 290Mb memory and 20% process usage. Hard drive space is 60% free. I have occasionally seen the memory usage spike to 100%. MalwareBytes showed a total of two instances and none since. Where else can one look to identify the problem?1 person needs an answerI do too

Boot into safe mode and see how it functions.And when you ran winupdate, you didnt make the mistake of installing recommended updates, which would have included drivers, did you?PS malwarebytes is solely a malware app, its not an AV app, and you dont mention any AV

Like Palcouk says check your AV. If your machine is infected you will need to clean it before you can look elsewhere for the problem.If you think my answers are helpful please vote and mark as possible answer. Thank you.

If you mean something like this:Internet Explorer cannot display the webpage Most likely causes:You are not connected to the Internet. The website is encountering problems. There might be a typing error in the address. So, let's verify your network connection properties.Some malware will tamper with these settings and your anti malware software can't tell if you changed them or malware changed them so after removing any infections, it will just leave the settings as it finds them (this is usually a good thing) but may leave your Internet access disabled.Click Start, Run and in the box enter:inetcpl.cplClick OK to launch the Internet Properties control panel applet, choose Connections, LAN settings. Or, from Internet Explorer click Tools, Internet Options, Connections, LAN Settings.

Automatically detect setting = checkedUse automatic configuration script = UNcheckedUse a proxy server for your LAN = UNcheckedMake any adjustments and click OK, OK to save the settings.Check your settings for the way your network adapter obtains it's IP and DNS settings. On most home systems, these settings should be set so the system will obtain the settings automatically. If you have another system on your network that is working, you can compare those settings with the settings on the system that is not working and make adjustments.Click Start, Settings, Control Panel, Network Connections and select your current network connection.On the General tab, click Properties.In the drop down list in the middle, locate and highlight the Internet Protocol (TCP/IP) selection and click Properties.In the Internet Protocol Properties window, the usual selections are to obtain the IP and DNS settings automatically. Enable the following two options:Obtain an IP address automaticallyObtain DNS Server address automaticallyThe rest of the options in the screen should then be grayed out/unavailable.Make any adjustments and click OK, OK to save the settings.Restart your computer and test your connectivity.If it still doesn't work, verify your adjustments are still in place after a restart and then release and renew the IP configuration settings from your network device.Click Start, Run and in the box enter:cmdClick OK to open a command prompt window and then type in the following commands:ipconfig /releaseipconfig /renewexitRestart your computer and test your connectivity.Download, install, update and do a full scan with these free malware detection programs then resolve any remaining issues:Malwarebytes (MBAM): http://malwarebytes.org/SUPERAntiSpyware: (SAS): http://www.superantispyware.com/These can be uninstalled later if desired.Don't guess what the problem might be - figure it out and fix it.
