Uninstall some stuff from you PC...Use an antivirus that consumes less RAM.
And don't tinker around X-Live, it brings freezes most of the times.
And use a program called CacheBoost - Its effective and it cleanse up the Cache from useless junk.

I didn't say it happens for everyone... I said it was a known problem.
