Hi I`m hoping someone can help me. I have Alienware aurora desk top running on windows 7 64 bit if you need any more information about my aurora just let me know. A few days ago I think I picked up a virus on it and it just went into melt down so after trying everything I did a clean install and reloaded all the drivers from the dell driver site and as far as I know in the right order ? . It all seems to be working fine expect two things .one it keeps saying Unknown Device: Device type Universal Serial Bus controllers Windows has stopped this device because it has reported problems. (Code 43) .I’ve tried uninstalling and reinstalling the driver again and again still no joy!!! and the second one is after installing the new Alienware command centre I started it up it opened on the thermal systems controls I noticed that all the thermal status were on 0% and the Hard Drive Fan2 and CPU pump said Failed . I’ve run loads of Diagnostics test they all come fine .The funny thing is it seems to be running fine oh and the lights don’t work but I’m thinking if the command centre isn’t working neither will they
