HI ! Yesterday I opened my computer and cleaned the inside because it was full of dust. After I started it I have gotten a Blue Screen Error quite alot (every 15-30 mins) This is not the first time I've cleaned the inside of this computer and have cleaned a few others too but nothing like that ever happend. I have also tried reinstalling windows and formatting everything but it still happens (a little less often though) View attachment 012813-34062-01.zip I have just got this one again Crash dump file: C:\Windows\Minidump\012813-22546-01.dmp Date/time: 28.1.2013 12:10:49 GMT Uptime: 00:06:54 Machine: Bug check name: VIDEO_SCHEDULER_INTERNAL_ERROR Bug check code: 0x119 Bug check parm 1: 0x1 Bug check parm 2: 0xF10000 Bug check parm 3: 0x0 Bug check parm 4: 0x0 Probably caused by: watchdog.sys Driver description: Watchdog Driver Driver product: Microsoft® Windows® Operating System Driver company: Microsoft Corporation OS build: Built by: 7600.17118.amd64fre.win7_gdr.120830-0334 Architecture: x64 (64 bit) CPU count: 2 Page size: 4096 Bug check description: This indicates that the video scheduler has detected a fatal violation.
