"Not enough memory available" message when there is...

[CtrlZ]

I am having a lot of trouble getting my computer to stay on for more than a couple of hours ever since installing Windows 7. Since I got past reinstalling all my programs and started actually using the computer I noticed these error messages coming up when I was running iTunes and firefox at the same time. After a while of testing I discovered that in fact iTunes alone was enough to trigger the message. I have since discovered that in fact I don't need to be running anything, and the memory still runs rampant.

At first I thought this was a virtual memory issue. I tried turning that off, which made it worse. I then tried spllitting my virtual memory evenly between my non-system drives. This helped quite a lot, but still the computer will be unuseable after only a couple of hours depending on what I am doing. Eventually if try and continue using the computer the screen will just go completely black.

I have found that in Resource monitor even when I don't run any programs my 'modifed' memory and to some extent my 'In use' memory just climb and climb. I also note that wmpnetwk.exe appears to be using more than its fair share. It drops back every so often, but I have seen it climb to more than 1.5 gig while the system is idle. At the moment it has 4,002,098KB under 'Commit' and 1,155,960KB under 'Working Set'.

Please help me

We need your hardware info. Download HWInfo32 and fill in your details.

I started putting in my hardware once I posted the question. I have included Mobo, CPU, Graphics, OS, RAM. Is that enough? Will HWInfo get what you need on 64 bit windows?

OS Windows 7 x64
CPU Intel Core i5 750 Lynnfield 2.66GHz 8MB LGA1156
Motherboard ASUS P7P55D PRO
Memory SuperTalent Gold Series 4GB (2x2) DDR3-1600 CL9
Graphics Card(s) XFX Geforce 9600GT

HWInfo is stunning - if it won't find it, it doesn't exist. Start by taking out one RAM stick, and then clocking it down to 1333MHz - i5 technically only supports 1333mhz. Then update all your drivers - BIOS, chipset, gpu, sound, ethernet, etc. Then upload a shot of your installed programs and the msconfig startup tab. What antivirus are you using?

Question:

Do you have any other operating systems installed?

I don't have any other operating systems installed. I am running COMODO internet security.
