Windows 7 professional, 32bit, Critical error, Kernel-Power, event Id: 41' task cat: 63__

In the past 48 hours I have waded through dozens of posts on different forums trying to find solutions to this fundamental problem, one that undermines the whole basis of upgrading from Vista to Windows 7.

I was running Vista Business and decided to upgrade to Win7 Professional, using Windows Upgrade.

All good, until I left my pc on Friday night, came down Saturday morning, and found BSOD, stuck on Memory Dump at 40. Result: no memory dump. When I next left the pc later that day - BSOD. Same on Sunday morning. So I checked in Event Viewer.

Everytime the PC tries to wake from sleep I get BSOD.

Here's the message in Event Viewer:

Log Name:     System

The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

Sometimes the bugcheck code is 000, sometimes 292.

To cut this short I've run debugger on the one partial memory dump, having had to download the SDK amongst other things. That, as it was incomplete gave me:

BUGCHECK_STR:  0x124_GenuineIntel


I've checked all my drivers including Realtek. I've run troubleshooter on the Power Options. I've adjusted the hibernation times, but I'm not prepared to accept a software fault and run my machine at 100% 24/7, just because this upgrade won't allow me to put my machine to sleep and wake up.

I've run *powercfg -h on*

I've tried to track down * error 0x80070057*

I've put my memory, and cpu settings back to stock. They were only slightly adjusted in vtune anyway, and worked perfectly in Vista.

I am running an Acer Veriton M464 E4700 Intel Core 2 Duo @2.60GHz 2Gb Ram

I just don't believe that given all these instances of this happening, especially to people who've upgraded from Vista Business to Windows Professional, that there isn't a solution to it.

I hope someone from microsoft can help. Thank you.


One thing, there appears to be  Acer programs installed, some of which are loading drivers such as the elock2fsctldriver.sys which can be problematic.

I would suggest, at least temporarily, to uninstall all Acer programs.

Also uninstall any NVIDIA programs such as nTune.

Also, the NVIDIA Driver Helper service crashed a couple of times so consider, at least temporarily, disabling this service.

Also, there does not appear to be a Realtek audio driver installed so consider installing the Realtek audio driver available from Acer or try the generic driver from Realtek.

Also, consider entering the BIOS and loading the BIOS default settings.

The Bugcheck 124 you are experiencing is of the MACHINE_CHECK_EXCEPTION variety, there is some info on that in the following link which info is for XP but generally applies to Windows 7:

Also, if the errors occur only when the computer sleeps the problem may be with a specific hardware/driver that does not react well with Windows 7 power management.

You could try temporarily disabling some hardware devices, such as the NIC, and see if that makes a difference. 

Did this solve your problem?

Sorry this didn't help.

Great! Thanks for marking this as the answer.
