Windows 10: Can't shutdown my computer after enable fast startup

When I try to enable fast startup in the power settings, I am unable to shut down properly, Windows will auto reboot after a minute by itself.I have tried deleting and recreating the MSR and EFI partitions, and ensured they are adequately sized, but the problem persists.I also cannot find any relevant error information about event ID "45". How I can resolve this issue?

Abnormal shutdowns with Fast Startup enabled

Thanks Sumit - No, as you say, it's an Intel: i5 (8th gen - 8250U) with Intel UHD 620 graphics, 8 GB RAM and an SSD. I'll have a try with Dell as you suggest. These abnormal shutdowns are definitely not random - they happen on almost all attempts at a
Fast Startup shutdown, though occasionally shutdown and subsequent startup do succeed. Oddly, full hibernate works correctly.

 

Abnormal shutdowns with Fast Startup enabled

Hello - I recently (18/6/2018) set up a new laptop(Dell Vostro 5370) which for the most part is running well, but Reliability History shows frequent "Windows was not properly shut down" events, which a sleep study report from powercfg shows are associated
with transitions into what the sleep study labels as "Shutdown (hybrid)". There are corresponding critical Kernel-Power event ID41 entries in Event Viewer. Turning off Fast Startup seems to work round the issue, but it would be good not to have to do this.
As well as updating everything in sight I have tried the usual checks with DISM and sfc, and run the hardware checks in Dell's SupportAssist, but they show no problem. I have also run the Boot Performance (Fast Startup) assessment in the Windows Assessment
Toolkit, but this just reports that it cannot complete the assessment owing to a system crash. Can anyone suggest any other troubleshooting steps, or remedies? Thanks...

 

Pc problem, randomly doesn't turn on sometimes.
