Video playback problem on PC but not on laptop.

[Riley Blue]

A couple of years ago I bought a Crosstour CT9900 action cam to record car trips. It saves MOV files which I convert to MP4 to edit on my PC - or will when I've learnt how. Playback of both file types is good on my Lenovo laptop but not on my PC where video playback 'stutters' constantly. Both are Win10, 64bit.

Where should I be looking to remedy this: processor, memory, drivers or...?

Responses in simple terms please, my knowledge of computer hardware is basic.

It could be a host of issues from drivers, configuration, the app. But I would make sure all updates have been applied to your computer first. Then fire up task manager and check what resources are being used, do you have sufficient memory, what other programs are running, disk usage, performance monitor, Start here.

likely to be either not enough CPU on the desktop, or possibly graphics card not helping to decode the video.

If you right click on the start button on each machine and select "device manager" , what does it say under display adapters ?

Laptop:
Intel(R) HD Graphics Family
NVIDIA GeForce840M

PC:
Intel(R) HD Graphics 4600

Presumably I should update both drivers to whatever the latest version of each is?

4K 60fps

Later drivers may help, as may trying different video playback software, but depending on what video standard it is encoding too that's a pretty demanding resolution/frame rate.
