Welcome to the forum.
What version of PrE are you using?
What version of OS are you using?
The answer might well be in those data.
You have not given us enough information to help you.
What version of Premiere Elements are you using and on what computer operating system is it running?
For Premiere Elements to take full advantage of your computer resources it needs to be a version that runs as a 64 bit application in a 64 bit system. If you have Premiere Elements 10, 11, or 12 on Windows 7, 8, or 8.1 64 bit that will be the case. If you have Premiere Elements 11 or 12 on Mac 64 bit, that will be the case.
All others, Premiere Elements will be a 32 bit application running as 32 bit in a 32 bit computer operating system OR a 32 bit application running in the 32 bit compatibility mode of a 64 bit system. Key thought here is that, 32 bit system has maximum supported installed RAM = 4 GB and 3 GB or less of that are available.
Please fill in the necessary details so that we can go from generalizations to what you actually have.
Looking forward to your follow up.
Premiere Elements version 9.
Windows 7 64-bit

As ATR said in reply #2, it takes version 10 or later to be 64bit... your v9 is 32bit and will only show/use what a 32bit program is capable of doing
Thanks for the confirming information.
Please refer to my prior post.
So, the bottom line is that you will need to install Premiere Elements 10, 11, or 12 on your Windows 7 64 bit computer in order for those specific programs to take advantage of the 64 bit system resources.
But, please go the free 30 day tryout route from Adobe before any purchase. The tryout from Adobe is only the current version which is 12. There is a marked change in workspaces after Premiere Elements 10 so be on guard for that.
Please do not hesitate to ask if you need clarification on anything that I have written.
Thanks for the info. I'll try version 12.
