Today, while skype is running in my notebook, it suddenty crashed and closed. I re-try to open it and while it is opening after the login window appears one sec it suddenly hiding and skype begins to use %100 of one of my CPU while it says Signing in..

I wait a lot but it could not signed in. Also it continued to use my cpu %100. I tried many things (restarting, even re-installing skype) but had no luck.

In the event logs there was an event like;

Faulting application name: Skype.exe, version: 5.3.0.111, time stamp: 0x4dac4a84
Faulting module name: Skype.exe, version: 5.3.0.111, time stamp: 0x4dac4a84
Exception code: 0xc0000005
Fault offset: 0x006eb5e2
Faulting process id: 0x1764
Faulting application start time: 0x01cc1b778e56eb5d
Faulting application path: C:\Program Files (x86)\Skype\Phone\Skype.exe
Faulting module path: C:\Program Files (x86)\Skype\Phone\Skype.exe
Report Id: 4f47742a-8789-11e0-a319-f07bcbef9a23

After that I tried to run my skype from the command line with the following command;

"C:\Program Files (x86)\skype\Phone\Skype.exe" /nosplash /maximized

and it fixed.

May be you have the same problem and this information might help to you...

NOT: The path is for the 64bit platforms, if you are using 32 bit windows then you should use;

"C:\Program Files\skype\Phone\Skype.exe" /nosplash /maximized
