Partially frozen system

Twice today my mouse (a Logitech USB optical mouse) and keyboard (an old Dell PS/2 keyboard) stopped working. At that point it was a bit hard to tell what else had stopped working, but the second time I was not at the PC when the devices stopped working and the screensaver had kicked in by the time I noticed. Neither the mouse (whose light was now out) nor the keyboard would bring the display back. I would suspect a driver but these 2 devices are pretty unrelated.

Can anyone suggest some debugging action?
I ran Windows_NT6_BSOD_v3.03_jcgriff2_.exe even though this wasn't a BSOD problem. Should I attach the results?

Pat Please look in event viewer

There are several ways to find what the problem is. The best is to go into event viewer (type eventvwr in search). Go to the windows log>application tab.

You want to look for critical errors (they have red in the left column ).

When you find them you want to look for critical errors that say app hang, app crash, or anything that relates to the problem.

When you find them please note the event ID, and the source codes and tell us what they are.

Since opening this thread I've had another freeze and an unexpected reboot (no BSOD). Even so, I'm not seeing anything useful in the logs. (That could be just my inexperience causing me to miss things.)

No Application and Service log entries for today.
Windows Logs - Application: nothing but Info and a couple Warning entries
Windows Logs - System: pairs of significant events for each reboot

Log Name: System

Event ID: 41
Task Category: (63)
Level: Critical
Keywords: (2)
User: SYSTEM
Computer: Patrick-PC
Description:
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

Not exactly helpful info. When my mouse and keyboard stopped working I had no choice but to reboot out from under the frozen system.

The only other slightly suspicious event I see (a Warning that occurs about 11 minute after each reboot) is

Log Name: System
Source: Microsoft-Windows-DNS-Client
Event ID: 1014
Description:
Name resolution for the name dns_registration.domain.actdsltmp timed out after none of the configured DNS servers responded.

None of this seems terribly helpful.
