I've had an HP Pavilion Slim for almost 2 years now and it's been having problems almost right out the gate. I've had my sound repeat the last note quickly before crashing and only a reboot of the computer will restore the sound. This doesn't happen all the time but it's irritating. The Desktop Window Manager (DWM.exe) crashes within minutes of the computer starting up and sometimes resets itself but I'm unsure if it's affecting other parts of the computer or OS. IE and Firefox go completely black and lock up forcing a manual close or even a complete computer reboot. The removable media storage and DVD-RW drive will occasionally not recognize devices or will freeze. The Explorer will randomly crash and not allow a reboot except manual reboot. Anytime we're playing Flash games over the internet that's when IE or Firefox are more prone to crash, freeze up, lose sound or cause a blue screen. On the blue screen the reasons for crashing have varied and we have about 2 pages worth of different reasons.
We recently upgraded from Windows Vista Home Premium to Windows 7 Home Premium before the New Year and the problems have persisted.
Examples of the blue screen crash errors we've received are:
Modification of a system code or error
The dxgkrnl has encountered an unexpected fatal error
I recently went through a cleaning session with chamber and he has classified my computer as CLEAN. I appreciate any help and willing to take any suggestions before my wife decides to toss the computer out the second-story window and into a 5 foot snow bank. Thank you for your help.
