Anybody Else Having Major Issues with RAM in Windows 8?

Hello everyone,

I am having an issue with Windows 8 and I was hoping someone in this forum could help me resolve it. I have a desktop with 12gb of ram installed (I use it for video work). For some strange reason, WIndows keeps on popping up messages saying that I am running out of ram. This occurs even when I am just surfing the web. I looked at Windows Task Manager and it stated that my memory was 86% full. This is strange because I looked at the specific programs and all of them don't add up to 86% of 12GB. I have tried changing the virtual page size (change from automatic to no paging to set custom size), but it hasn't helped. I am totally stuck and would appreciate any help!

Thanks
