Help diagnosing a "freezing" problem
Solution 1:
Can you please try to do my procedure here and answer with a link to the trace in a comment, I'll look into it.
Just start to run it each time before you do a Skype conversation or watch a Flash video...
When looking at your trace I see several values spike up to 100% after Skype: CPU, I/O and so on...
I/O isn't really 100% because it just can't update the graph anymore because of the hang, so let's ignore that.
One of your CPU cores is up to 100% because of the System process, and more specifically DPCs.
So, right clicking on the DPC CPU Usage graph and going to Summary Table reveals this:
NDIS is the Network Driver Interface Specification, which indicates that network related stuff is going wrong.
This makes sense, because you are calling with someone over a connection or streaming a video over one.
There are probably dropped or bad packets that are causing your device or driver to fail...
Thus, you should first try to do the following two possible solutions:
Get the latest network drivers for your system, not from the CD. If you have latest, try an older version...
Replace the network card if that doesn't help.
This should normally solve the issue, as I've often seen network drivers cause these problems.
If not, feel free to report back to us so we can look further into the problem...
Solution 2:
My advice is to check that the firmware for the OCZ Vertex 2 is the latest. I built a computer for a friend with that SSD and we had a lot of problems until I updated the firmware on the SSD. And I hope you are running it in AHCI mode.
Solution 3:
Just a guess, is there a 64-bits version of Skype ? Have you tried the 32-bits version ?
I had a vaguely similar problem with 32/64 java VM.
Have you tried changing your webcam and mic ? Updating their drivers ?
Have you tried turning it off and on again ?
