Help: Resources Draining my Server to Crash

[ajwmedia]

Seems Bi Social Network our most successful site is having issues with our servers. I was asked to get off Rochens shared server, then I paid the larger fee to get my own MVS now it's crashed and they had to reboot it. How can you check to see whats it could be? Is it the theme, the plugins, the component features, the bandwith, I"m so at a lost on this, and don't even have all the money to find a network guy to find out why this would be happening. They had to reboot my server.

They are saying this:

Your sites, in particular bisocialnetwork.com seems to be using a large amount of resources even on your MVS. I'd suggest you review and optimize this site. Ensure caching is on in Joomla's global configuration and check all components are up to date and secure along with all Joomla core installs as well.


All my sites are WordPress, and simple configurations.... would it be GF? Causing this? This is very recent and I've had the site for 2.5 years. The first theme being Church and just moved over to News...

Any help would be great to see what it could be..
