A quick and to the point of the issue, and things I have tried to resolve this. The laptop is an i7 with 8GB of (some kind) ram, Win 7 64bit, etc.
Boot and load times are not an issue, however with nearly any program, be it Excel or Photoshop, mouse inputs are beyond slow. I have to hover over a button for a second before it even highlights. It seems that if the programs are open for a little while that it is somewhat better, but still not acceptable for how new the computer is. CPU usage and memory usage are very low and no particular process seems to be hogging resources and causing the issue.
I have formatted and completed a new install within the month, ran the computer with minimal programs installed, with all drivers and windows updates installed with no change. It's not a virus or any kind of malware. I have tried various sizes of virtual memory/ paging file with no change either. I've tried another set of memory modules with perhaps a slight improvement, but it could have been the placebo effect as well. My gaming rig I built works perfectly with none of this nonsense, but I can't figure it out aside from blaming it on something that HP has installed, or with its proprietary drivers that are causing some conflict.
Also, I've tried running an external mouse with the integrated touchpad disabled.
