Here is a suggestion which I found on a Microsoft web site, which makes good sense to me:
Disconnect all external devices, then reboot your computer. If that fixes the problem, then do the following for each device you disconnected, one device at a time:
* Shut down the computer.
* Connect a device.
* Restart the computer.
If the problem returns at any point, then the problem is related to the device you just reconnected to the computer. Reinstall the driver for that device, or install a newer driver for the device.
Here's where I found the information:
Srttrail.txt error and keeps on automatic repairing
If the above doesn't fix this for you, then it would be a good idea to try to read the srttrail.txt file, to see if it has helpful information. See if you can get into Safe Mode - If you can, then you can likely read that file. To get into Safe Mode, restart the computer, then start tapping on the F8 key till you see a menu - choose Safe Mode or Safe Mode with Networking.
