Hello everyone, since I bought a new laptop this year in February, I have this problem. When I'm surfing at home, I don't get any BSODs, but when I log in the WLAN at a friend's house, my laptop crashes after about half an hour. At home, I use WLAN as well. The problem also is time-related. It only happens between, lets say, 3 and 10 pm (Maybe because at this time other persons surf in this network?). When I disconnect, I don't get any BSODs. Currently I am in Safe Mode where I don't get BSODs as well. Here is the problem signature and the last minidump file. (I believe that the problem signature is always the same) BCCode: 7f BCP1: 0000000000000008 BCP2: 0000000080050033 BCP3: 00000000000006F8 BCP4: FFFFF80003048E58 OS Version: 6_1_7600 Service Pack: 0_0 Product: 768_1 Event ID is 1031. Oh, and I'm using Windows 7 Home Premium 64bit. Thanks in advance for any help!
