Super noob here... I know cars but not much about computers, and next-to-no exposure to win 7, so please bear with! Bought a Toshiba a505 used, a few months old, from a lady who knows less than I about computers. Her boss, a "computer expert," messed with it, putting things like norton and office on. They tried to remove norton at some point, but it was still there but not working. i've managed to delete most, if not all of it, but i'm sure there are residual pieces around. I'm not sure if it is the cause of my problem, but does seem to be the error i get in the diagnostics attached below. As far as I can tell, everything works fine except it won't dl updates (for things like avg and itunes, but will dl windows updates) and some programs (like norton's removal tool). It says that connection to server failed, and other various warnings of similar nature (cannot connect, cannot open page, check connection) I tried some of the suggestions, including diagnostic results. even clicking on the "explanation of error codes link" pulls up an explorer page that won't connect. the results: ----- Error Symptom: Device is not present, not working properly, or does not have all of its drivers installed (this is a link) Cause: A device has a configuration problem that prevents it from working properly. Details: The device, BHDrvx64, is reporting "tv_ConfigMgrErr24". This device will not be available until the issue is resolved. The Plug and Play ID for this device is ROOT\LEGACY_BHDRVX64\0000. Resolution: 1. Verify the correct driver is installed. 2. Try updating the drivers using Windows Update. 3. Check with the manufacturer for an updated driver. 4. Attempt to uninstall and then reinstall the device using Device Manager. Related: Explanation of Error Codes Generated by Device Manager, Manage Devices in Windows Informational Symptom: The Security Center has not recorded an anti-virus product. Cause: The Security Center is unable to identify an active anti-virus application. Either there is no anti-virus product installed or it is not recognized. Resolution: 1. Verify that an anti-virus product is installed. 2. If an anti-virus product is installed and functioning configure Security Center to stop monitoring anti-virus status. ----- I'm using the computer now, so it obviously works partially. appreciate any ideas!
