I've had the PH315-51 for about a month now and from the start, I notice that the cursor would sometimes exhibit "flaky" movement, i.e. stuck-ish / laggy, whenever I launch any random program. I cannot replicate it every time with the same programme, it seems to happen randomly with any program. Sometimes it's when launching Firefox, sometimes File Explorer, sometimes even the Predator Sense. Sometimes it even happens as the browser loads a webpage. I noticed that the same thing happens even with a USB mouse.
I've updated the BIOS and touchpad driver to the latest version available, and the problem still hasn't gone away.
Please help as it is very annoying - the more so knowing the system is actually a powerful one and shouldn't be experiencing this. I also hasten to add that when this happens if any audio or video is playing, they are NOT affected.
If it helps, I replaced the 1TB HDD with a Sandisk SSD and the RAM with an 8GB HyperX 2666MHz module.
TIA.
