I have a Dell Inspiron 15 that is four days old. I moved Windows 10 on to this laptop and all the downloads I have on this laptop (to the best of my knowledge) were the same as on my previous laptop.
I noticed at first there was a delay or slowness that I wouldn't have expected with a new machine while typing in Chrome or Firefox or even the start menu. It wasn't a complete halt, but not as fast as I thought it should be compared to my older laptop. I reinstalled Firefox, and that helped a bit. But there still was that lag, especially when bringing up a new tab in any of the browser windows (Edge included).
After a while, I went to the Task Manager. I noticed that the memory percentage, when idle, hands between 45 to 60 percent. The CPU can hold down around 20 percent when idle. When I open any of the browsers or open a new tab, that spikes to around or at 100 percent. If, with no other pages open, I watch a video online, it will stay at 100 percent on the CPU for at least a minute before ramping down.
Needless to say, I found it surprising to see this in a new laptop. There has been no real performance issue in a sense, but it just seems slower at the start and can slow more than I expect while playing a video.
I have run Malwarebytes (clean, twice). Same with SuperAntiSpyware. My Avast gives me no hits in terms of a virus. Troubleshooter finds nothing, as well.
The biggest users seem to be whichever browser is open, Task Manager, WMI Provider Host, Synaptics TouchPad64 and System Interrupts. I even uninstalled Malwarebytes (I since reinstalled) and checked the Task Manager when I opened up Firefox -- the result was a spike to 100 in CPU (it held around 30-35 after a while) when I opened the browser and memory that held around 45-47 percent.
So my questions are -- is this what is causing the lag time or is it just my expectations for a new laptop? Also, if this is my problem, any ideas?
