Why does Windows 7 64-bit stop responding?

By ejames6342 ·
I have a Dell Inspiron 1545 T4200 at 200 Ghz with 3 GB RAM as well as a 2 GB USB key using Ready Boost. I also have 1.3 terrabytes of space in two external hard drives.

After doing a clean install of Windows 7 64-bit I've noticed an annoying problem. About five or more times an hour my PC will stop responding for a few seconds and then it works fine. I just wait 5 or 10 seconds and it is okay. I've noticed that if I don't want to wait I can start task manager and everything immediately unfreezes. It is like a pregnant pause which is kind of annoying.

On a daily basis I scan for viruses, defrag my hard drive and run Glary utilities. I have upgraded to all 64-bit applications where available and I don't run any applications that are not compatible with Windows 7. I've checked the memory for seven passes and it is okay. I have 150 MB left on my c: drive so disk cache space is not a problem. I also ran the windows system file checker and all is fine. All of my drivers are native Windows 7 64-bit drivers and Windows update is run daily.

I can't figure out what is causing this problem. I had no problem with this computer running Vista 32-bit. I would greatly appreciate some ideas here, even if they are only suggestions and not THE solution.
