Sure. Here it is with no virtual PC. Note the 1GB free.

That's a dedicated graphics card with 256MB memory on-board, so I don't see why it would be pulling any memory from the system. Do you also have an integrated graphics card? What specific desktop model do you have?

And I would not worry too much about performance. With 4GBs, you are pretty well equipped. Just make sure that you do not have a lot of junk starting with the startups. Only the AV program is really necessary.
Well, I also have Carbonite, Google Desktop, and LogMeIn. I eliminated a bunch of other stuff, but the machine isn't as fast as others with Windows 7 with the same memory and, in fact, can be downright slow at times.

Check out this thread:

Installed memory(RAM): 4GB (2.94GB Usable)

You might not have "memory remapping" enabled in your BIOS, or you may have the maximum memory limit denoted in the msconfig instructions.

Looking at your Resource Monitor, you do not seem to have a lot of page faults. Thus you are not starving from memory. If you post the Resource Monitor again, set the "Hard fault" column such that the processes with the most faults show up on top. Also make the snip such that the graph on the bottom right shows. That will give us a better picture of your paging activity.

The reason for the slow performance is probably your disk. If you installed a small SSD (e.g. 60GB) for the OS, that would cure it.

You might not have "memory remapping" enabled in your BIOS, or you may have the maximum memory limit denoted in the msconfig instructions.
After checking out the memory remapping and msconfig suggestions, take a look at the dell drivers site:

Drivers & Downloads

It looks like there's a BIOS update for your machine as well. That might be good to do, even if it doesn't fix this issue.

The motherboard/chipset only supports up to 4 GB of ram and unless there is a memory re-mapping option available (being a Dell, doubtful), then this is what is likely happening,

The usable memory may be less than the installed memory on Windows 7-based computers

this one explains it further,

The system memory that is reported in the System Information dialog box in Windows Vista is less than you expect if 4 GB of RAM is installed

Quote:
The BIOS must support the memory remapping feature. The memory remapping feature allows for the segment of system memory that was previously overwritten by the Peripheral Component Interconnect (PCI) configuration space to be remapped above the 4 GB address line. This feature must be enabled in the BIOS configuration utility on the computer. View your computer product documentation for instructions that explain how to enable this feature. Many consumer-oriented computers may not support the memory remapping feature. No standard terminology is used in documentation or in BIOS configuration utilities for this feature. Therefore, you may have to read the descriptions of the various BIOS configuration settings that are available to determine whether any of the settings enable the memory remapping feature.
Quote:
Note When the physical RAM that is installed on a computer equals the address space that is supported by the chipset, the total system memory that is available to the operating system is always less than the physical RAM that is installed. For example, consider a computer that has an Intel 975X chipset that supports 8 GB of address space. If you install 8 GB of RAM, the system memory that is available to the operating system will be reduced by the PCI configuration requirements. In this scenario, PCI configuration requirements reduce the memory that is available to the operating system by an amount that is between approximately 200 MB and approximately 1 GB. The reduction depends on the configuration.
Basically comes down to once you reach the limit of what the motherboard support for total memory it doesn't matter whether you have 32 bit or 64 bit Windows, the addressing space needs to come from somewhere.

That is a good possibility as the G33 chipset on that motherboard is supposed to support up to 8 GB,

Intel® G33 Express Chipset - Overview

and it is possible that Dell "fixed" it in one of the 7 bios updates from the date of the one currently installed (1.0.5).
