Bit of a hard sell on bad hardware as the computer is 1 month old and worked very well using win 7. However, it is possible. Before I bought the machine I went thru the Dell Win 8 upgrade notes
Windows 8 General Upgrade Troubleshooting | Dell and specifically for the M6600
Precision Windows 8 Upgrade Product Support | Dell . I purposely kept from loading software prior to the upgrade so as to reduce the chances of having the exact problems I am having now. I was meticulous in following the M6600 guidelines for upgrading to win 8.
That said, I remembered that in the general guidelines that Dell recommended uninstalling the bluetooh software and reinstalling after the upgrade. I uninstalled bluetooth but did not have to reinstall it as win 8 did it automatically.
Yesterday, after your reply, I shutdown the verifier (machine was just to slow to do anything) and since I have no bluetooth devices, at present, uninstalled the bluetooth and clicked on the delete driver box when presented. I shutdown the computer, it did not bsod. Upon restart the computer stayed in black screen for a long period but when win 8 finally came up the touchscreen and digitizer were working better than ever. I checked device manager and the bluetooth driver was back. I uninstalled it again and shutdown. No bsod, upon restart it took 1m40sec to get to the lock screen and 1m5sec to get to the start page and touch and digitizer were still working also the computer was responding much faster. Device manager still shows the bluetooth driver, aparentlly, win 8 wants the computer to have a driver, however, the driver is not a generic microsoft driver but is a dell driver with a microsoft bluetooth emulator.
I shut the computer down and restarted it 3 more times with no bsods, and upon restarting the computer it seemed to be back to win 7 speeds and responsiveness. Nvidia had another update for the quad 4000 so I updated it and performed a restart and it worked, all seemed okay until last night when the machine blue screened on shutdown. The SF file is attached. This morning it took only 30 seconds from switch "on" to win 8 start screen. All is working but last night's blue screen is annoying.
Could it be that win 8 is loading drivers that are not exactly the ones dell wants for this particular machine or the drivers from dell and msft are not loaded in the proper order? Why does the bluetooth driver keep coming back? Is there a way to uninstall then reload the drivers in the proper order or one at a time?
Thanks
