Hi, I am using windows 7 on my Hp Pavilion dm4 1024-tx laptop. Today while trying to connect internet to my laptop with my nokia c3-01 phone I faced the BSOD. It happens only when I try to connect to internet with my phone, whether through bluetooth or USB-Cable. Normal bluetooth/USB connections with phone occur without any problem. But I am able to use Wifi as well as ethernet. I tried several times connecting but with the same result, I tried uninstalling the bluetooth driver also. This is the error message I get after log on: Problem signature: Problem Event Name: BlueScreen OS Version: 6.1.7600.2.0.0.256.1 Locale ID: 1033 Additional information about the problem: BCCode: 100000d1 BCP1: 00000038 BCP2: 00000002 BCP3: 00000000 BCP4: 90B0E697 OS Version: 6_1_7600 Service Pack: 0_0 Product: 256_1 It would be immense help if someone can help me out. I don't know what to do, and I am afraid in case I become unable to use wi-fi and ethernet also. I have attached the .dmp file in .rar . Thanks in advance.
