Problem after upgrading to Window 7 Ultimate

Recently I have upgraded from Window 7 basic to Ultimate. Now Bluetooth is not working. I have checked Bluetooth driver and all are up-to-date. Also I am feeling video quality is worse compare to previous. Again all graphic card drivers are latest. Please guide me to solve those problems.
Notebook details –
Aspire 7752G
I5-2450M 2.5 GHz
NVIDIA GeForce 610M with 1 GB Dedicated VRAM & Intel HD Graphics 3000
4 GB DDR3
Thanks.

 

To try and pin down the problem, the drivers should be removed then reinstalled.

Make sure to go to the manufacturer website and download any newer version of the driver.

Uninstall drivers in this order and any separate parts showing in programs and features,

Bluetooth
NVidia graphic
Intel graphic

Reinstall in reverse, Intel first.

 

Thanks for your reply.
I have already installed latest version of driver from manufacturer's web site.

 

i suspect that this is due to scaling enabled by default.

 

Thanks for reply.
I can not find the way to disable scaling. What is the solution then?
Thanks.

 

So then the Bluetooth is working now?

Drivers sometimes have a particular install order and sometimes dependent on another driver being installed ahead of it.

Bluetooth may be dependent on WiFi being there first. If something went badly during upgrade with WiFi integration you'd want to try removing both and reinstalling.
Same thing with graphics. Intel should be ahead of NVidia, but if there are problems then uninstall and reinstall both.

Is the resolution set to the defaults for the LCD or were they changed?

 

Thanks for your reply.
Bluetooth is still not working.
I will try as per your suggestions. What will be the sequence of installation for Bluetooth/Wifi and also for Intel/NVidia?
Thanks.

 

Reboot when prompted.

Uninstall Bluetooth then Wifi.
Uninstall NVidia (there are going to be between 2 and 4 different items, leave the Audio if one is there) then Intel Graphics.

Reinstall Intel Graphics then NVidia.
Reinstall Wifi then Bluetooth.

All of this is to try and avoid doing a clean reimage. Otherwise figuring it out is like finding a needle in a haystack.

If you've searched around and haven't seen any real good fixes for it then you're going find it necessary if unhappy with the dysfunction.

Everything was ok before the upgrade, so that much is known.

Was it a factory image that was on it prior? Do you have specifically a "System Reserved" partition in disk management?

 

I will follow your instructions. Hope it works.
Yes it does have "System Reserved" partition in disk management.
Thanks

 

Good that you have that SR partition, iirc, BitLocker won't enable properly without it if at all.

 

There was Wifi/Bluetooth UI in my PC. After clicking Ctrl+wireless (F3) key the UI appear. From where Bluetooth, Wifi can be activated or deactivated.
After up-gradation I also lost this UI.
I have checked Acer web page. But not able to find something related this.
Any idea for bring it back?
Thanks.

 

That would be a OEM software package to control specific model Hot Keys.

Find the name and download, uninstall then reinstall it.

That may be something worth trying for that problem.

 

Now I found that particular software form Acer webpage. It was located in application section. Its name is" LaunchManager_Dritek_5.1.4_W7x86W7x64"
I have installed and uninstalled then re install. But it does not solve the problem.

"Uninstall Bluetooth then Wifi.
Uninstall NVidia (there are going to be between 2 and 4 different items, leave the Audio if one is there) then Intel Graphics.

Re install Intel Graphics then NVidia.
Re install Wifi then Bluetooth."

I have uninstall all those drivers as per given sequence. But unable to install as per given sequence. While uninstalling it was asking for restart for proper uninstall.
After restart it automatically install all drivers. After PC finises all installation I manually check and update drivers.
But still I am in same condition.
Hope you will show me some more idea to deal with the situalion.
Thanks.

 

I think something went bad with the upgrade but I cannot pin it down in my head.
I've experience that problem before, when uninstalling, upon reboot it would reinstall the drivers on its own. Yeah don't ask me how, I don't know where it was getting the software to even do that; it was on a factory image, so that may have something to do with it depending on the complexities of their driver installations.
The only thing I could suggest is to uninstall "all" those drivers again, reboot when prompted. Do this until they are all out.
Then go into the Program Files folder and delete the folder for NVidia, WiFi, and Bluetooth. I don't think it is a good idea or necessary to do this part with the Intel graphics as it could be too easy to delete the wrong folder. You can also search in explorer and try to find any stray folders.

Hopefully someone else could lend some ideas to avoid having to reimage. If it comes to needing to do that, I can lend you some good tips.

In any case, backup your data thoroughly; don't want to lose that by any accident or oversight.

EDIT:

Forgot to add, when everything is out, reboot again, then reinstall the drivers for IntelGraphics, Nvidia Graphics, WiFi, Bluetooth.

 

Also be sure to have the correct driver as it seems there are either Atheros or Broadcom drivers out there.

I would recommend

system drivers
Network driver
Then intel and nvidia
Them sound
And at last bluetooth ... In that order
