I can't find ANYONE who knows how to solve this problem so any help would be appreciated. I have just recently upgraded my RAM from 512 mb to 2 gigs. Physically I replaced 1 stick of 512 ram with 2 sticks of 1024 ram. Right off I assumed everything worked right. When the machine booted CMOS recognized the new ram just fine. When I got into Windows I check real quick in Control Panel/System to make sure Windows recognized it and it showed my installed 2 gigs just fine. What made me question was that nothing was running any faster. I was shocked by that seing how I just boosted my RAM 4 TIMES what it was. I opened Windows System Information and found that for some reason Windows was still only seeing 512 megs of RAM. In fact the information shown didn't even make any sense because it showed that I had 512 megs of total memory and 1,800 megs of AVAILABLE memory. So my problem is that my computer knows there is 2 gigs of memory there but is only using 512 megs of it. Has anyone had this happen before? Once again, any help is greatly appreciated. Here is a screenshot too if it helps.
