BSOD when entering Sleep mode

My laptop crashes almost every time it attempts to enter sleep mode. When I close the lid or select sleep or hibernate from the start menu, the computer will hang, and it sounds like it is accessing the hard drive. The computer will not respond to any input other than holding down the power button for a hard reset. If left untouched, the machine will eventually crash, and pushing the power button will cause it to boot with a message that the machine had recovered from an automatic shutdown.

This started as an intermittent problem, but now occurs nearly every time the machine attempts to enter sleep mode.

Below is the info shown in the dialog box that pops up after booting from the crash.

Thanks for any and all help!

I followed the instructions that ARC Posted in this thread, and I was able to sleep my machine for the first time in weeks. Will update again if the problem re-occurs.

You cannot blame the computer for it. It is you only who is forcing the computer to run 22 items always in the background.

Free up the startup. Windows does not need any other program to auto start with it, but the auto start programs often conflicts and causes various problems including BSODs.

1. Click on the Start button
2. Type “msconfig (without quotes), click the resulting link. It will open the System Configuration window.
3. Select the “Startup” tab.
4. Deselect all items other than the antivirus and the touchpad driver, SynTPEnh.
5. Apply > OK
6. Accept then restart.

Report us for any further issue.
