Solved CPU usage spikes to 100%, almost randomly.

Specs: Windows 64, AMD X2 4400+ 2.3GHz / 2 gigs
When running most games (modern ones, I'm assuming) and even some webpages, the entire computer runs at least 4x slower (especially noticeable in-game).

I've opened up the task manager and resource manager, but the processes never add up to the 100% usage shown under the performance tab of the task manager.

Not sure if it's relevant, but my physical used memory seems a little high, too (60%~).
CPU usage just peaked again while running a sysem assessment. No processes even over 10.

I've also already run a few virus checks, etc.

70c? thats too high, a good temp is 50-60c on full load.

Open your PC, clean out the dust with a air can at a distance, DON'T use a hoover.

Reapply your thermal paste-http://www.techpowerup.com/printarticle.php?id=134

I am a hardware guy not a software guy but i try to help.

Hidden backround programs use CPU resources aswell, 2GB on a 64-bit OS is not enough for gaming, will perform better on a 32-bit OS because of lower RAM usage.

What anti-virus do you have, some anti viruses like norton use a lot of resources, free anti-viruses are usually lighter.

Thanks for the reply, but after a bit of searching, I found out how to look at my CPU temperature... and it was 70C.

From what I've seen, it looks like this is most likely the culprit.

Still, any other theories or suggestions are welcome!

You've only posted partial specs & what is "Windows 64"? Is that XP, Vista or Win7? 2GB is the minimum for Win7 64-bit so if that's what you have, you shouldn't expect stellar performance. And if you don't have a decent gaming card, you shouldn't expect decent gaming performance, especially on newer graphics intense games.

Bring up Task Manager, Processes tab, click on the column heading for CPU to align the processes by usage. You may have to click twice to bring the hoggish programs to the top. Which one is using the highest percentage?

You should also run MSCONFIG to check your startup programs. Very few are actually necessary, but I've seen systems that have dozens listed. Disable the ones you don't need, then reboot.

You can also use CCleaner Slim to clean out your internet garbage files & check your startup apps.

Thanks for all the suggestions, but it was definitely the temperature.
A bit of dusting and thermal gel, and average temp dropped ~10 degrees. Everything is runnning smoothly again.
