Blue Screen error 0x0000003b and 0x0000007e

Hey guys,

I need some help and advise.

I just got my new laptop (Studio 17") Yesterday. I put in my TV tunner card and attached the portable arial to it. I then went into Windows Media Centre and went to tune in the TV and search for signals. As it was searching for signals (it reached 40% and none were found) it sudenly just went into a blue screen and restarted. I tried it again and the same thing happend 3 times.

The error message that came with the blue screen had 0x0000003b on it as the error.

I now have just found a new Blue screen error that i also need help with. When I close my screen, then lift it back up again, the laptop shows the log in for a few seconds then goes into that blue screen error. This time the error is 0x0000007e.

Can anyone please help me? What should I do?

Cheers,
