Hi all,

Since last week I've been experiencing a issue with my PC rebooting without warning. The issue occurs at seemingly random times, and give no error messages. Most of the time it's during full screen applications, but it has occurred once whilst having several tabs with youtube open at one time. There doesn't seem to be any pattern to the frequency either. Sometime's its after half and hour after opening the application, sometimes it's five minutes.

My specs are as follows:

CPU: AMD FX-4350 Quad Core CPU (4.3/4.2GHZ - 4MB CACHE/AM3+)
Motherboard: ASUS® M5A97 LE R2.0 (DDR3, USB3.0, 6Gb/s)
OS: Windows 10 64Bit

I've been trying to isolate the issue without much luck. Last week everything worked fine, and the only new installation since then was a Nvidia graphics driver. I've tried uninstalling and reverting to an older driver, and also installing the latest one that was released today, but the same thing occurs. I've also monitored temperature levels, and everything's fine there. I've tried a system restore, and I've run a memory check, with no issues, but I'm still getting reboots.

In the Event Viewer, the crashes appear as Critical Event 41s (Kernal-Power). Not entirely sure what this means, as the description is pretty vague. I've also disabled auto-restart to try and see a BSOD, but none appears. Just black screen for a second, then restart.

Any help would be greatly appreciated, as I've hit a bit of a wall here.

Many thanks,

The EventID 41 error is the key - but it is not the answer.

The error simply means that Windows shut down - and that Windows doesn't know why it shut down.

More info on this error at this link:  http://support.microsoft.com/kb/2028504


What we do is we look at the errors before the EventID 41 and see if we can find a pattern.
If there is no pattern, then a hardware problem is the most likely issue.  From your description, it seems to be hardware related.

So, while you're waiting for a reply, please get started with these free hardware diagnostics:  http://www.carrona.org/hwdiag.html


Let's have a look at this report.  Please do the following:
- open Event Viewer (run eventvwr.msc from the "Run" dialog)
- expand the Custom Views category (left click on the > next to the words "Custom Views")
- right click on Administrative Events
- select "Save all Events in Custom View as..."
- save the file as Admin.evtx
- zip up the file (right click on it, select "Send to", select "Compressed (zipped) folder")
- upload it with your next post (if it's too big, then upload it to a free file-hosting service and post a link here).

FYI - If we're looking for Event ID 41 errors (unexplained shutdowns), there's more info on that here:  http://support.microsoft.com/kb/2028504
