Windows 7: CPU usage spikes (100%) and windows lags terribly

CPU usage spikes (100%) and windows lags terribly

I have a Dell inspiron e1505. 2 gb RAM.

Essentially I am getting seemingly random spikes in my cpu usage where it ramps up to 100% and windows basically freezes for an extended period of time. Sometimes I simply have 1 google chrome tab open with no other apps actively running in the foreground and I get these cpu spikes. I just did a clean install of windows 7 to try and eradicate this and it persists. I am at a loss as to what the problem is. What is odd is even though the cpu usage spikes at 100% my available memory is almost always nearly around 50% still. So I am just not sure what is happening.

Here is a link to another forum where someone else was trying to help (unfortunately to no avail) High CPU usage, programs crashing, windows hanging - Tech Support Forum

Anyway like I said I eventually just did a clean install but the problem persists. Since the clean install I have not noticed and flash problems with chrome (as per the tech support forum thread) just random cpu spikes.

Any help is much appreciated

Have you open task manager to see what process is using the CPU at the time your load is 100%?

Yeah. No one thing continually pops up. That's why I am so confused.

Could be the hardware doing it then. Try turning off power management for your hard disk. Also run a utility to check the smart data and see if the drive is relocating sectors. Could be the drive dying.
