I have a dell vostro 1710 laptop that I've just finished putting back together and I ran into a problem immediately that as soon as I boot into windows, the PC immediately shuts down. Power cord has been plugged in and unplugged, makes no difference either way. I believe the problem is within my WLAN socket, when I remove the card, everything goes smooth and works fine. I don't think it's the card itself because I have switched out the card for another one and it seems to make no difference. I can successfully use an external WLAN usb device, but this is an inconvenience. Anyone have any ideas why WLAN can cause my computer to instantly shut down? Also, if I switch the wifi switch to the off position, I can startup and run fine, but as soon as I switch it to on the computer instantly shuts down. It was all working fine about 2 weeks ago then after I came back from leaving it unattended, and it was shutdown, I didn't think anything about it then I restarted it and it instantly died. It would seem like the laptop dies when the WLAN card receives power (this doesn't happen in POST?) because I can run the PC fine in safe mode (assuming because safe mode doesn't power up the WLAN card) The computer is windows 7, I have 4gig of ram, and a duo core processor.

Boot the computer using a rescue disk in PE mode, (a version of Windows that loads from the disk), then switch your wifi adapter on and see what happens. If it still shuts down, then you have a physical issue with the motherboard.
