I'm using visual studio 2010 SP1Rel with no extensions and the devenv.exe process continuously uses an entire core, making using the IDE very difficult, if not impossible.
I've noticed that svchost.exe -k netsvcs is also using an entire core.
I've run Process Explorer to try to identify what is happening, and I noticed that both of these processes has one thread that is hogging all the CPU and both threads are in the same function ntoskrnl.exe!KeSetEvent+0x6ca
The stack trace for svchost.exe is
ntoskrnl.exe!KeSetEvent+0x6ca

Has anyone seen this before? I was hoping someone could point me in the right direction as I have no clue how to proceed. I've restarted visual studio multiple times and rebooted multiple time but to no avail. A couple minutes after launching VS, the problem with devenv.exe reoccurs and the svchost.exe -k netsvcs issues comes and goes.
Any help would be appreciated. Thanks
I'm not sure why, but closing most of the files I had open in visual studio seemed to resolve the issue
