I've been having a lot of problems with my dell inspiron n5030 laptop with windows 7 64 bit and had to get a new hard-drive, plus do a clean install of windows 7. Now my laptop is running slow. I did some search and one site suggested I check my CPU. I did and it's very high, especially during startup. Within a few seconds it will go between 0% up to 79%! Processes say between 45-51 and physical memory says 26-48%. I've gone to run and typed in msconfig, there are only a handful of programs during startup and a few I was able to remove. What can I do to get my CPU to go down. I'm not going anything and when I do open a program like Microsoft Word, Internet Explorer, Photoshop...etc it's very slow.
