Unknown Proccess in Task Mangager

[manwiththeplan]

My computer has been running very sluggish lately and I'm trying to get to the bottom of what is causing it to do this. I notice upon opening my task manager that I have 6 processes running without any sort of description. They are:

NvStreamUserAgent.exe
csrss.exe
nvxdsync.exe
nvvsvc.exe
winlogon.exe
conhost.exe

When I try to right click and go to the file location or properties page of any of these unknown processes nothing pops up. On the other hand when I right click on a process with a description and select Open File Location/Properties it works normally.

Is it possible that there is something on my computer that is restricting me from looking at the details involved with these unknown process's? If not, how can I check the properties of these processes to do more diagnostics?

This is all abridged notes from http/www.file.net/
I gave you the most likely information, there is more on each process located there.
You shouldn't have much reason to be concerned, however viruses and trojans come in all shapes and sizes meaning technically any of those /could/ be, and if you are very worried I invite you to check on that site about what they suggest doing to make sure.

Hope this helps!
