Hi I also have such problem which is that my computer always crashs and restart when I'm wifing. (it even crashed when I was typing this message!) I thought it is the problem with the network drive and went to Lenovo(my comp is thinkpad x201i) but they said there's no update available.. I do hope that you can help me and I appreciate it here's the error report: Problem signature: Problem Event Name: BlueScreen OS Version: 6.1.7600.2.0.0.256.48 Locale ID: 2052 Additional information about the problem: BCCode: d1 BCP1: 00000000 BCP2: 00000002 BCP3: 00000000 BCP4: 9124AAB8 OS Version: 6_1_7600 Service Pack: 0_0 Product: 256_1 Files that help describe the problem: C:\Windows\Minidump\011111-21824-01.dmp C:\Users\waynewing\AppData\Local\Temp\WER-40700-0.sysdata.xml THX A LOT!
