This is really becoming irritating now - after roughly an hour after I switch on my wireless from my laptop, it suddenly disconnects from my router. When I try to reconnect, it blue screens. I've been told that I may need to update some bits which I've tried. But it continues to blue screen.

Now my second problem is eveytime I try to turn on my laptop, it starts then after a few seconds, switches itslef off; if I leave the plug on, it does this continuously. After a while, it tells me to do System Restore (which I do and the laptop runs fine). But when I turn it off and turn it back on, it doesn the same as the above.

I'm suspecting hard drive corruption or failure or something else....

Any help please?
