Several windows update error codes

I can't see anything wrong with the WinEVT entries (but I haven't been able to check in detail) - there's no obvious signs of corruption present, and the entries I did inspect in detail all matched up with my own.

Let's have a look at the logs themselves...

Please open Event Viewer
In the left pane, navigate to the Windows Logs
right-click on Applications and select 'Save all events as...' save as Apps.evtx
repeat for the System logs - save as Sys.evtx
Compress both files, and attach to your reply.

...and my apologies, in turn!
Here's some snippets from the logs..

The Steam Client Service service failed to start

STEAM is known to have compatibility problems - and can affect the whole system.
Please uninstall it until we have sorted out the current problems, as it may get in the way.

You have a number of system crashes there. Most are '000A'errors (IRQL failures) which are often caused by driver problems.
Please ensure that all installed drivers are up-to-date.


If you follow the Blue Screen of Death (BSOD) Posting Instructions then I'll ask a BSOD specialist to look over the resulting data, and we'll see what they have to say.
