Is this a store bought or custom build? With 32 bit W7 OS you'll be limited to 4gb of ram with less actually usable and in this day and age with ram so cheap it's a 64 bit OS world. Bottom line is you should consider maxing out the ram with 2x2gb ram modules and I would look to matching pairs in 1600 mhz from Corsair, Crucial, G Skills or better yet go to the mfgr's site or mobo mfgr's site and look up the approved ram off their site.
As Greg mentioned running CC cleaner that often is way overkill. If you complete the spec's on your rig we can offer better suggestions. Lastly when was the last time you open the rig up and cleaned the fans, cooler fins and such?
