My laptop is extremely slow. I just reloaded the OS (windows 10) and it made no difference. I noticed something odd in that when I look in Task manager on the Performance tab, the CPU is only 23% utilized AND the clock speed is ONLY 0.5GHz as shown with the utilization percentage. The advertised clock rate is 2.16 GHz which does show up in the Properties tab as well as in Task manager (as part of the header). It seems like my CPU usage is stuck at 23%. I have only seen it move down to 22% on occasion and never up.
As an example, I used the Detect This PC option on the Dell Support website and it took over 10 minutes for it to respond.
IT appears that my laptop is only running at 0.5GHz. The slowness of the pc would tend to support such a slow speed. For the record, the slowness is in everything from opening Windows Explorer to browsing any website. I changed the Power Plan to High Performance but it made no difference. The laptop has 4G of RAM. Does anyone know why my pc is only utilizing 1/4 of the clock speed?

10 minutes is a very long time. You were able get into your Dell Product Support page and downloaded / installed any drivers onto the system ? Is the computer brand new ( per nyc10036)? What is the exact Dell model number and version of windows? Example: Dell Inspiron 3543 windows 10. If you don't know, type msinfo32 onto search box, stroll down System Model, you should see it now. Lastly, boot into safe mode to see if computer is lagging or going slow.
Using safe mode to troubleshoot problems on your Windows 10 PC
Thanks for your reply. It is an Inspiron 15 3531. Win 10 Pro (most current version). The laptop is about 5 years old. I don't know if it EVER ran better than it does now. It was given to me by a friend. Safe mode made no difference. I also made sure that the Page File memory was large enough (set per MS recommended size).
Does anyone know if there is a way to increase the performance/clock speed?
