Strange problem loading games

[spoony77]

Not sure if this is the right forum or maybe it should be in the windows forum.
I have a strange problem with my windows 10 pc where no games will load on first boot - they always say 'failed to load' or 'error in loading'.
If I reboot my pc everything loads up just fine?
Seems bizarre I know lol.
Anyone shed some light on what could be causing this issue - seems I have a pc that boots like lightening now I have windows 10 but is unusable for gaming till I've rebooted it!!

There are no error codes as such.
It is steam games that I notice it on mainly as the majority of my games are based there but its the same for emulators outside steam as well.
I'm definitely booting from whatever Windows 10's version of shut-down is (some sort of low power state as I can load windows just by pressing the keyboard)....
