After putting on my Columbo detective raincoat & hat I find that, if the op's profile is correct, that he's on a Lenovo Ideacentre all-in-one like one of these:
https://www.lenovo.com/us/en/ideacentre/aio-300-series/c/AIO-300-Series
and that he's on PT Express and Windows 10 Home. If you drill down into the specs they're not all that powerful. Some have Intel and some AMD. There's even a model that has a 5400 rpm spinner as system drive and none have more than 8 gig ram.
One more thing - PT Express is only compatible up to Win 7 sp1
