AMD Radeon HD 6400M error "Windows has stopped this device because it has reported problems. (code 43)"


May 23, 2015

I have DELL Inspiron 15R-n5110

It has 2 Graphic cards: Intel HD Graphics 3000 and AMD Radeon HD 6400M

Processor: Intel(R) Core(TM) i3-2330M CPU @ 2.20 GHz

6.00 GB RAM

Windows 7 Ultimate SP1 64 bit

I just re-installed everything as my Windows Experience Index was only 3,4 and I wanted to boost it (I had problems with AMD Radeon drivers before)

So when I re-install drivers - it says everything is ok etc. (screen below)

But when I restart my computer - it gives "Windows has stopped this device because it has reported problems. (code 43)" error (screen below)

My Windows Experience Index is 5.6 now and everything works kinda nicely

CCC shows that everything is ok

I have Microsoft Framework 4.5 installed, as well Direct X 11

I just have no idea why on startup my PC can't start AMD Graphic drivers properly

I tried Microsoft programs that fixes problems for you and re-installs the drivers - it didn't worked

I tried once more to uninstall everything, I prevented auto installations with "gpedit.msc" method, then I installed AMD Graphics 6400M first and restarted PC - everything seemed to be OK. Then I installed Intel HD Graphics 3000 and then I got this message -

So I get similar problems all the time when I try to install both AMD Radeon Graphics and Intel HD Graphics 3000 drivers - I just don't know how to make them both to work together.v

Anyone have any ideas what to do ?

BTW all drivers I downloaded from DELL "Drivers and Downloads" section using my service tag. Maybe it has something to do with registry keys ?

When I uninstall drivers - I go through the Device manager and when i uninstall them, I choose to delete all settings to, to completely wipe drivers out of PC and then try to re-install. Nothing works - it still gives me Code 43 error
