Thanks for your replies guys, I really appreciate you getting back to me so soon.
Check that the USB plug is not damaged or distorted in some manner. May be just a bit off that it first works and then due to vibration or heat causes a short. Especially if connected via the I/O panel.
Also take a look in Reliability History for error codes, warnings, etc.. Similiar to Event Viewer but much more user friendly. The timeline format can be revealing as well.
Does the old/original keyboard cause any problems?
If only the new Asena keyboard causes the shutdowns then the keyboard is likely defective.
USB indeed. I have tried every USB port on my PC with the same result. Might have a look to see if my USB hub doodad is still around here somewhere.
Reliability History doesn't seem to contain anything of note other than the time and date of the unexpected shutdown/windows was not properly shut down etc.
I have tried two other old keyboards with no issues.
Try other USB ports to rule bad port/bad connection.
How shortly? Seconds, minutes, almost instantly?
See above about the USBs.
It seems to be fine if I leave it plugged in and don't touch it, but as soon as I try to type anything it triggers the shut down.
If it failed immediately, I would suspect a short in the usb connector or wiring.
Since it happens later, I suspect that some sort of keyboard software is being loaded that is causing the problem.
Try loading windows in safe mode. F8. That loads windows with only a minimum of drivers.
Me, I would return the keyboard as defective and move on.
Yeah, the shut down doesn't seem to occur until I actually try to type using the keyboard. Interestingly, only some of the keys seem to work in the moments before the shutdown.
What would I do after loading windows in safe mode?
Unfortunately, I don't have a receipt or anything for it, but it's no big deal as it was a cheapo heavily discounted item (which may say something about the malfunctioning.) Then again, I don't really have money for anything more at the moment, so I'd really like to get this up and running if I can somehow.
Additional: I have restarted in safe mode and can confirm that the issue persists.
