It's back...

I get the hard freeze or hang up, whatever you call it, where the vista circle is spinning, and for 2-3 min you can't do anything. Then all goes back to normal.

This was happening quite a bit a few months ago.
I installed more Ram, and ran a pc cleaner, which helped, wasn't getting any for a while. Now I get them now and then.

Any ideas on what this is ? I think it has to do with system usage etc. someone said maybe virtual memory.....
Any tweaks I can do ?

Vista home premium - service pack 2
Intel (R) CPU 2160 @1.8 Ghz 1.8 ghz
Memory 3.0 GB
32 bit

Try a clean boot. Then re-enable services one by one until you find the one causing the slow boot.
