cPanel server load acting weird, any ideas?

hey everyone, still wrestling with those pesky cPanel warnings from the last thread. we've tried a bunch of stuff, honest.

the main headache is the server load just won't quit, even after optimizing our site and DB. it's like it has a mind of its own, refusing to chill out.

any thoughts on what else could be causing such stubborn high server load numbers? what specific diagnostix should i be running to finally put this to rest? waiting for an expert reply.
