Dave,   ejn63 is very good at this, but if you want to check for yourself...   Pre-Boot System Assessment (PSA) Diagnostics and Error Codes For Dell Computers   Start making copies of files and folders that you cannot afford to lose. Like I state, this should be a normal practice. If the hard drive failed tomorrow, you would have the files and folders needed.   Yes, the hard drive is under warranty. Contact Dell Tech Support. Depending on the model, if they're hard to get to, then they send out a technician. If they can be replaced easy, then you'll have to install and send the old hard drive back. Looks like they'll probably have you install it, unless there is some special contract. INSTRUCTIONS HERE.   The hard drive they send you will install the system automatically. I replaced one on my daughters computer and Dell sent a technician out for My Dell XPX L501x. I didn't lose anything as it was found in time.   Keep us posted. If you need help with installing the programs that do not install, using Internet Explorer, go to My Dell Downloads :: Login use the same email address and password you use here, then click on add system. The paid media that does not install will be available for download there.     Rick
Hi folks My Vostro Notebook 3700 was restored to a previous state by our IT chap and now I can't connect to any wireless network I've tried connecting to both open and password protected networks (all of which the router is functioning fine with other computers) and in every case, in the DW WLAN Card Utility, in the Link Status tab I am shown to be connected, with the connection status "Authenticated" but the Gateway IP address, Client IP address are shown as "Not available" When I use the Diagnostics tab and run "Connection diagnostics", I get "failed" when it gets to Authentication. Any assistance in helping me to solve this problem would be most gratefully received Many thanks in advance Dave
