GeForce Go 6150 co-processor video / driver fix, Windows 7, DV2000, 64x2 AMD, WinXP / Vista

[Dextro-Middyin]

I wish I had found Daniel's 'dv2000 Windows 7 Updrade Guide' first... it would have helped speed things up! Took me two days to get everything running propperly!

Next Laptop won't be HP... their support bites.

Laymans fix if you can't get anything else to work... Good luck... NO warranties implied!

CHIPSET DRIVERS - Solution on yellow mark with COPROCESSOR

Procedure works on most all 'DVxxxx' model laptops and a few other models as well with the GeForce GO 6150. (Yes I have successfully done it.) No third party apps required. You should upgrade/have 2GB of Ram minimum, 2.5 preferred. (System maxes out at 2.62GB on DV2000 when using 32 bit Win7). A full backup and Bios update should be performed before starting!

1) Go to HP`s site and Download several different drivers for 'GeForce Go 6150', or just 'GeForce 6150', GeForce 6150SE/nForce 4xx, 6 Series, etc. (sp33031.exe/sp39535.exe/and 195.81 from the 'Beta section', etc.) Also grab a few others by searching your computer 'Model/type' for driver updates. Grab the ones for whatever OS you upgraded FROM. (xp or vista). Grab whatever looks close! Be sure to check between 32 or 64 bit OS! (As per Daniel: sp36607.exe for vista)

('search' the HP site for the driver names to find the drivers faster).

DO NOT install any yet after the downloads.

2) Make a 'Restore Point' on your system. See windows7 Help if you don't know what that is or how. Go to Windows Update FIRST. Get ALL updates EXCEPT the one for the Network Card that is available there (unless that IS your model card). Install/Reboot. MAKE ANOTHER RESTORE POINT NOW. This should have fixed the GeForce 'video' driver issue and the SD card reader issues and the Hotkey issues with drivers, etc, but will still leave you with 1 driver issue.

It may be listed as a "co processor" but it is actually the "nForce System Management Controller" that needs the driver. (part of the GeForce software/chip).

3) Go to Control Panel, Hardware and Sound, Devices and Printers. Double click on the computer/drive/icon showing yellow 'errors'.

4) Harware Tab, Properties, Change Settings. Update driver for the missing 'nVidia display card' FIRST... IF not already done/fixed through Windows Update.

Search for driver via 'manual search' in the "C:\Windows.Old" folder created during upgrade to Win7.

*Don't forget to check the "search subfolders" box!

If Windows Update did not work and there is no "Windows.Old" folder on your C: ...you can try again to update the 'video' driver through Windows Update (Microsoft site) immediately after installing Win7. (Plus the bunch of security patches too). Also try any relevant service packs from HP you already downloaded... but follow instructions below if you get ANY 'error' messages. Reboot.

5) Co-processor will still show as error and 'no drivers'. (but video driver should be fixed by now).

6) Try installing 'sp33031.exe' for "nForce" first. Even if it says "not installed" or "failed" or "no drivers for your system" don`t worry. DO NOT try to "re-install" with "Windows recommendations/settings". Just close the dialog box with (X).

The driver is from 06 (5.1.2600.114) but works.

6) Reboot. Go back to Step 3. Do a manual search for the driver for the 'co-processor'. But this time list the location as; C:\Swsetup\sp33031 (or the name of the relevant service pack, if you already tried this one). Again, make sure the "Subfolder search" box is checked.

Driver should install. If it still can't find a driver, you can also use the same method and manually check any service packs in 'Swsetup', or any 'nvidia' folder on C as well.

7) Close the Hardare/Device window. Wait 10-15 seconds. Re-open the window... and with any luck and NO FN HELP FROM HP, your co-processor is now happy.

If that driver didn't work... apply the same method with other similar drivers until you get one that works. For models other than DV2000, after the 33031 and other service packs: try the beta 195.81

After each driver install attempt, even if there were errors: Try to Update the driver again as described above.

'Unistall' the last driver ONLY IF it even actually fully installed, from the "Unistall Programs" link in Control Panel. ***(Be careful not to unistall the existing 'NVIDIA' driver in the list that is for the main video driver you already fixed!!! Only 'uninstall' from the control panel if there are TWO listings for nVidia, but there shouldn't be if you properly 'X' closed any error dialog window as mentioned earlier.

IF needed, due to an accidentally installed wrong driver.... revert to your backed-up "Restore Point" and then start again and try the next driver/service pack.

*** WARNING *** Before even starting all this... Also check your BIOS version!

Backup everything and update the Bios before upgrading to Win7 to avoid a 'stopped fan' issue.

*If you have already upgraded, check your Bios version anyways and update it!

There are instructions on the HP site of how to do it and there used to be a 'bios checking' tool. There was a problem/recall for overheating in the past due to a bad Bios fan algorythem that was frying video cards/displays. Just running Windows Update may not fix a fan from possibly running impropperly/stopping.

I need a beer.
