Hi
My Lenovo laptop has been performing really badly sometimes acting normally and sometimes being so slow I couldn't exit applications, randomly restating, having trouble restarting (I found it restarted after an alt-ctrl-del or two from the Lenovo splash
screen but I think it rolled back a recent windows 10 update)
During all this I had one BSOD that said
"the gpsvc service failed the sign-in.
The universal unique identifier (UUID) type is not supported"
- this only happened once - and may be a symptom not a cause.
The issues had started after a recent win 10 update.
I had trouble installing that update and had to update drivers via Device Manager to resolve compatibility issues. (I updated everything I could find - 4 drivers updated and it allowed win 10 update to install)
I checked the event logs and I have numerous warning errors appearing almost exactly a minute apart. (full details below, after I ask for help)
I am not fully aware of the hardware history - I bought it as warranty rebuild - but it has been working fine for about a year so I didn't think there was an issue with the machine. I don't know if these messages have always been there as I had no need
to check logs before.
I have run the hardware scans in the Lenovo Service Centre tool and they came out clean.
Please help - what can I do to identify the cause of my erratic performance problem. The error is technically just a warning -but handling so many can't be good for performance - so do I need to do something about it - and if so what?
Please be gentle with the help - I am a very technical Business Systems Analyst with pretty wide ranging experience, but I am no hardware engineer.
May thanks in advance
Sandra
