Dear all, 

I have accidentally deleted a very precious photo album present on my laptop. I have taken the habit of cleaning up my recycle bin once in a while and am sure that there is no trace of it in there.

Hi all, 

I just upgraded my laptop to windows 8.1 Pro x64. I have a Sony Vaio laptop,VPCEA1S1E, with an intel core i3 cpu and 4 GB of Ram. My main problem is that i can't find the latest driver for my graphic card which is the ATI mobility Radeon HD 4500 Series. When i open my device manager, i find two alerts under unknown devices. How can i fix this?

The Bluetooth adapter in my Dell core i3 N series laptop is not working and it shows a yellow exclamation mark when I go into the device manager. I have tried updating the driver for it and it says it is updated. The sign goes away for now but reappears again after a minute? What might be causing this problem? Is this a hardware driver related issue or is my Bluetooth adapter damaged?
