Not sure what happened but it must related to wireless. As my 2.4Ghx Linksys wireless adapter will be disconnected for no reason and when I unplug or disconnect from "Safely remove hardware", my computer will reboot automatically. Here I attached the minidump for your reference. Thanks

Both minidumps crash at usbohci.sys and have a bugcheck of D1.

This is undoubtedly something to do with your removing your wireless adapter.

Maybe the wireless adapter is faulty, or is in need of updated drivers. Failing that, try another adapter and see if that helps.

Thanks for your advice. Strange.. this problem did not occur when i used the same wireless adapter in another computer and i am using the same driver from the cd provided by linksys.
