I want to go back to your first post and clarify a couple of things. You said you "just upgraded to windows 7 64bit and went from two gig to 8 gig." Did you upgrade from Windows 7 32bit or something else? Did you use a Windows 7 OEM disk, a full install disk or an upgrade disk to do the clean install? Did you have any issues of any kind during the upgrade like Windows Updates not installing on first attempt, etc?
On the off chance that some glitch may have damaged or corrupted the system files and isn't allowing the memory to be properly recognized, you could try running a system file checker scan from an elevated command prompt (option two.) If any problems are found run the scan 3 times rebooting in between each scan. If SFC is able to fix any problems use your computer to see if the memory is being recognized and if the hardware reserve is other than 0MB.
SFC /SCANNOW Command - System File Checker
If SFC showed problems or not, you could also try doing a repair install which should preserve your user accounts, data, programs, system drivers, etc.
Repair Install
If this doesn't fix things I think a clean install would be warranted. But all of this speculation is based on the assumption that this is a software issue. If you have an undiagnosed hardware issue even a clean install probably won't fix things. And nothing is jumping out at me from your screenshot of Daz Studio 4.
