New problem to do with E6600, one core is constantly on 100%

Hey, as you can see from the previous thread I fixed the problem with windows not recognizing both my cores but now I have a new issue. In task manager and CPU history the first core onthe left is constnatly on 90-100%?

How many programs do have running at start-up?
Have you done a virus scan or checked for ad-ware?

I'm installing windows updates right now so it will have a bit of load on it, but nothing like that is happening on the left. As you can see nothing is using any time except for the updater.

Well how would I know? I haven't heard of it or noticed it before so I doubt it.

Contol panel, System, System Restore.

I found this, don't really know WHAT it is but this could be the trouble.

"What is mscorsvw.exe and why is it eating up my CPU? What is this new CLR Optimization Service?
Short version:

mscorsvw.exe is precompiling .NET assemblies in the background. Once it's done, it will go away. Typically, after you install the .NET Redist, it will be done with the high priority assemblies in 5 to 10 minutes and then will wait until your computer is idle to process the low priority assemblies. Once it does that it will shutdown and you won't see mscorsvw.exe. One important thing is that while you may see 100% CPU usage, the compilation happens in a process with low priority, so it tries not to steal the CPU for other stuff you are doing. Once everything is compiled, assemblies will now be able to share pages across different processes and warm start up will be typically much faster, so we're not throwing away your cycles."

Well, since you are currently updating and loading new software, wait till you are completely done, then give it a few and see if the usage goes down. It could be an IRQ conflict with a card in your system, or a program stuck in a loop. I don't see anything right off either that would keep the one core so high.

I'm with JPub, since the screenshot of your running processes only showed mscorsvw.exe is the only thing other than the idle thread using CPU cycles. Maybe you could do another screenshot of your running processes, this time sort the CPU usage column to have the highest use items at the top. Click the CPU column title like three times and it will sort them in descending order. This will help determine for sure which process is using the most CPU resources. If your convinced that it's not mscorsvw.exe, then wait to take the screenshot until something besides it and the idle process show up at the top of the list. Other than that, here is the link that JITPub and I found:

Are you using a static IP address, and do you have your firewall installed yet?

If you unplug your internet connection, does it still do the same thing?

Now I believe something weird is occurring. Core 0 is nearly used up entirely while the other is idling, and you don't have any processes using up the CPU cylces. When I run a process (UD) which uses all up the resources of one core, even though it is singlethreaded, it distributes the load slightly like 80-20 (that's on individual cores). With yours it's like running the one at nearly 100% while showing that the idle process is running at 97%. This lead me to believe that Windows is still seeing your CPU as a single core in some manner. There is no way that it should be showing 97% on the idle thread and have one core used up like that, it should be saying like 50% on the idle thread.

Now you mentioned that you "solved" a problem where Windows wasn't recognizing it as dual core. If this isn't something to do with a conflict of some type, this maybe something to do with your original problem. Could you provide a link to the other post you mention.

what if you checked show processes from all users?

Have you installed graphics drivers, if not install them and see if that changes anything. Maybe without drivers the CPU is having to handle the desktop display under Standard VGA adapter.

EDIT: Never mind, I just looked back at your first screenshot, I see the nVidia System Tray icon.

I was thinking it coudl be that too but I put everything together again and nothing changed.

Yep sure, here you go http://forumz.tomshardware.com/har [...] 19479.html

I think that must be the prolbme, MPS says it applys to non APCI computers, but every modern computer supposrts APCI?

I thought the dual core hot fix only applied when cool and quiet was being used?

... look at this link.

It looks like your dotnet is screwed up. He addresses two possibilities for why your process is eating all the CPU time. COnsidering it seems he helped write the program its quite likely he knows what he is talking about...

Something was deffintely wrong with the hardware I think, windows installed 3x faster on this AMD 64 3200+ than my E6600
