Hi,From your description, is it true that the latest shutdown encounter an error, after that, the computer won't enter sleep mode? Any additional information would be more of help.Better try system restore first. If that does not work either, go to device manager, right click on your display card->propertise->under driver tab->Roll back driver.What is the model of your PC and display card? Install the latest display card driver to check the result.Please upload the C:\Windows\Minidump\020110-27534-01.dmp to SkyDrive and provide us the link for analyzing http://cid-4b2f155953942dc9.skydrive.live.com/summary.aspx The above Windows Live ID is ONLY for collecting troubleshooting information.

Hi rgordon44,Bluescreen needs to analyze the dump file and debug codes. To solid troubleshoot bluescreen issue, it is recommended to take Magon_67's suggestion to collect the crash dump files and contact Microsoft Customer Support Service (CSS) for assistance so that this problem can be resolved efficiently. BTW, I noticed an error 9f, you may refer to:Bug Check 0x9F: DRIVER_POWER_STATE_FAILUREIt did indicate that the issue may related to driver power failure. Best RegardsDale
