Hi, I run Win 7 on Lenovo Thinkpad T61. These days (3 days ago to now), computer randomly blue scree then shutdown and restart. After logging back in it says that it has recovered from an unexpected shutdown. It says it will check for a solution to the problem but then nothing else happens. I find the error in eventvwr like this: - System - Provider [ Name] Microsoft-Windows-WHEA-Logger [ Guid] {C26C4F3C-3F66-4E99-8F8A-39405CFED220} EventID 18 Version 0 Level 2 Task 0 Opcode 0 Keywords 0x8000000000000000 - TimeCreated [ SystemTime] 2011-06-08T12:52:42.353726200Z EventRecordID 96898 - Correlation [ ActivityID] {9FB38E67-A4AC-485F-A829-ADFF7EBC90B3} - Execution [ ProcessID] 2004 [ ThreadID] 3460 Channel System Computer Lirk - Security [ UserID] S-1-5-19 - EventData ErrorSource 3 ApicId 1 MCABank 5 MciStat 0xf200001010000e0f MciAddr 0x0 MciMisc 0x0 ErrorType 10 TransactionType 256 Participation 3 RequestType 0 MemorIO 3 MemHierarchyLvl 3 Timeout 0 OperationType 256 Channel 256 Length 928 RawData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the minidump link is here : http://cid-f6d8ac2592c69a7d.office.live.com/self.aspx/.Public/060911-57158-01.dmp Often when the win7 is startting , the picture is freeze and I have to force to shutdown it .
