Just some added thoughts..not sure how much help they’ll be.
… if the unloved style works on another pc therefore i would conclude that its something in the celeron pc, and not the style
… if i had problems with the unloved style eg the lead in or metronome or an RT
Then i would mute that problematic trak. Eg replacing the metronome with a drum
RT genned on a trak.
… frankly i never bother with the bb metronome…i use a trick ie the first 4 bars of
Any song use an rt a la D.d/D.d/D.d/D.d 4 bars lead in to a song using a 4 bar rt
Where no other instruments play.

As i said before there are various utilities you can run to see if anything is interrupting the audio process…eg

Its all a process of elimination eh ?
Ie try one thing …not that …try another etc etc

Just a nutty idea…does same prob occur in realband ?

Anyhoo thats all i got as ideas.

Frankly i dont like one drive laptops, too many probs ive seen with friends too …and agree with the microsoft product mgr for audio/midi (forgot his name) who owns a pretty snazzy recording rig…and published a very nice paper awhile back re daws.
Ie he runs a desktop.
