Hello Thaitobbe,

Please see your last topic started Feb 20th, 2010 and the link I provided previously.

"BEFORE you POST"(READ this Procedure BEFORE Requesting Assistance)

Please start a new topic and provide a HJT log for the initial analysis.

Best regards.

Edit: I see you have also requested assistance at another site.

Posters who start topics at multiple sites for their PC problem waste valuable volunteer resources, so please don't. Our analysts assist people at several forums. A member's user name may be different, the problem will not be. A worse scenario would be to run fixes given at one site unbeknown to the person helping the same user elsewhere.
