I wanted to upgrade my graphic card driver - so I've downloaded the new version from dell official web site. I got the error that it's not compatible.. I read somewhere that it's good to uninstall the previous driver and to install the new one.

1. I had to replace the old original batterie. I bought the same original Dell battery, but i still get the message that the battery has reached end of lifetime and should be replaced. (That is why I replaced it in the first place...) Is there a way to reset the message? 2.

i have had my dell xps 1645 for around a year now i bought it off a website second hand last night it just shut down now when i turn it on all i get is a flashing mute light and the volume up and down are solid lights.
