hey. i have a sony vgn-s260 laptop, about a year old. i just sent it in for repairs because i kept getting the same stop error over and over. they replaced the motherboard among other things, to no avail, it still has the same problem. the problem appeared 1 year to the date of purchase, (coincidence?)... anyway. here's the situation. when i turn my wifi switch on, and am browsing the internet, my laptop will stop error and reboot. i can't find a reason for it. it's random, no pattern. when the wifi is switched off, i have no problems. nothing new has been installed, no new hardware or software. i just upgraded my wifi router with the latest firmware, enabled a firewall, and added a password. i've scanned my hdd for spyware and viruses, to no avail, everything is clean. here's the catch though. a friend was over tonight using our wifi, and his computer did the same exact thing that mine does. blue screen, then reboot. i thought maybe it could be a mix of radio frequencies interfering with something just right to cause a problem, but that's a long shot. or also, since the wifi usage potentially causes more heat, it could be getting too hot? i'm not sure, seems like that'd be a fault of sony... i'm completely out of ideas here. any help would be appreciated. thanks. i've attached the latest 5 .dmp (mini dump) files if anyone wants to take a look at them, i have no idea how to make sense of those. again, thanks for any help.
