Okay so got a mates laptop to have a look at, it's pretty much annoying me now.
So its a Vaio with Vista Home Premium, which i did a clean install of cause it was screwed.

I can't get the WLAN card to work or turn on. After endless searching for a decent driver download, it says windows cannot load the drivers (in device manager). when i actually switch on the wireless card with the switch on the laptop itself, the LED next to the the 'ON' sign does not come on..

secondly, the screen keeps randomly going blank. i don't mean black or BSOD, it just seems to go the same colour as the background at that time, and no buttons do anything etc, so i have to do a force shutdown every time. I had a little peek inside and couldn't see anything out of place etc, but who knows. Tried doing the static removal thing, no luck. Also have installed latest graphics drivers so i don't think its the Graphics card.

Any help is much appreciated, thanks.
