This issue started about two weeks after replacing the broken motherboard on this computer. The new motherboard is an MSI. When it happens, things like Skype calls, Netflix and Minecraft seem to provoke it (Not all running at once), then when force closing the app taking all the CPU, something else seems to take it, almost as if there's suddenly not enough CPU time to go around. The system has a Intel Celeron D processor running at 3.0 Ghz, 4 GB of DDR3 memory, a 128 MB nVidia Video Card and is running Windows 7 Ultimate.
My attempts to fix this issue have involved the following:
- Re-Install Skype
- Re-Install drivers related to the issue (Audio, video, networking drivers)
- Adding more thermal compound to the CPU (I thought it was maybe overheating, it wasn't)
- Inspecting the processes taking all the CPU with it showing nothing odd.
- Running Malwarebytes, HiJack This and Avast antivirus, removing any infections found.
A restart of the computer fixes it temporarily, but it starts again after running those apps for awhile.
The only thing I have not tried is re-installing Windows, which I would like to avoid as this is my girlfriends computer and she is currently not near by for me to get access to the computer. The best I have is TeamViewer.
Any ideas on how to fix this issue?
