Honestly given the specs on your computer (from what I've googled based on the model name you posted) I'm surprised you're having the issues you're having. Normally the default "Jabos" plugins work the best (or at least on my system, which is much less powerful). The only explanation I have at this point is that your CPU "is" being throttled, if not by windows itself (since we've ruled this out adjusting the power settings), then maybe by your bios?
Easiest way to check (which I should have had you do originally) would be to download and install cpu-z, which you can get here; http://www.cpuid.com/downloads/cpu-z...1-setup-en.exe. Once it's installed run it, and it should pop up a window showing your system specs, including your processors current clockspeed under "Core Speed". Assuming I've correctly identified your laptop (this? http://www.amazon.com/Compaq-Presari.../dp/B0040JHMZI) it should read somewhere in the neighborhood of 2200 Mhz on Core Speed; if it reads something significantly lower, then your CPU is being throttled by something, which would explain the issue.
Edit: Another thought, a lot of times when you buy a computer with windows pre-installed it'll have all sorts of unnecessary crap preinstalled, and furthermore often they have a lot of stuff set to run automatically when you start your computer, wasting resources and being detrimental to performance overall. Assuming you haven't done this already, you could try disabling unnecessary startup programs if you'd like.
Here's a guide that would do a lot better job explaining the process than I could through this; http://netsquirrel.com/msconfig/msconfig_win7.html

"I think that the problem with this video is it is highly derivative of many popular bands within the genre. Although when viewed on its own merits, it does have a deeper groove. However what it has in groove, it lacks in originality. One can't help but be reminded of such bands as Pearl Jam, White Zombie, Suicidal Tendencies and other bands that bear the mantle of so called "Alternative Rock". One is even reminded of Lorie Anderson when she wore curlers. Hehehmhm! This video speaks less to the heart and more to the sphincter. In closing, I think Korn would do well to learn more from -"
