I received an error of "PBR2 . . .done, A disk read error occured. Press Ctl+Alt+Del to restart. I ran a diagnostic boot, no problems found, an extended diagnostic, no problems found and the extended test, no problems found. My computer is an Inspiron E1505, w/Media Direct. I had been getting blue screen errors of problems with my video driver and then others. I downloaded and reinstalled the drivers from the website, in the order that I was told from a previous PC restore (of which was for the same problem). This time I lost my ability to connect to the internet, wouldn't recognize my wi-fi, etc. Lost the ability to copy to disks. Pretty much was running in safe mode. Wasn't able to backup some key data due to the loss of copy ability. Does any know what to do? I uninstalled the tv tuner (external) that came with the computer back in September and this is when everything seemed to start. I was assured by support the first time that it couldn't/wouldn't have caused the problem(s). Thanks for any insight you can provide me.
