BSOD- due to .sys extension , possible VGA error ?

Bad News
I have been hit by the bluescreen again and now am logged in Safe mode
with networking i was following the above procedure and when i finished uninstalling
Quickheal and restarted pc i first encountered a " YOUR RADEON DRIVER
HAS stopped responding and has JUST RECOVERED "
then when i was watching a youtube video and reading ur steps and
also scanning using the microsoft security essential my lappy hung and
adobe pluigin crashed twice then i had to forefully restart it . i
had no bluescreen until this point but when i was about to goto device
manager to update the drivers i got hung again and the bluescreen
is showing up now ATIKMDAG.SYS and it wont let me work in normal mode
what should i do next , should i again uninstall all ATI thing and
reinsall drivers ?? thats what i did last time ...Btw when the lappy
is booting..am getting weird pattern of something like "" "" """ """ """ ON SCREEN
please tell me what to do next

When i try to uninstall it says windows cannot access it in safe mode
so i guess i cant uninstall it

couldnot initialise zoomgpu when i tried to initiate that software for videodrvier testing

it shows
NVIDIA
INTEL
AMD ..do i need to remove for all these three ?

i removed for everything now when i goto device manager
i cant see name of AMD RADEON 5650
It just shows STANDARD VGA GRAPHIC ADAPTOR
I tried using recovery disk ..it got stuck in between i forcefully restarted it
i cant do a fresh install as well as this windows installation can pre-installed .

but right now i dnt see any blue screen and its letting me login in normal mode too but the problem is that at bootup screen i get Pattern of many Dots in different color ..its like a mesh of dots ..also the AMD HD RADEON 5650 name dissappeared from the device manager list...when am trying to install software for amd radeon ..either am getting some kind of error or after installation am coming across the bluescreen with the error i mentioned earlier
i dont feel like changina nything to it right now ...i have exam on 16th of this month and i live in a remote place
i will try to use the laptop as it is till that date and then will follow ur suggestion if nothing happens :)
thanks a lot mate ..people like u are helping me and others selflessly i really appreciate it
God bless u

Update ::: I tested few things and now whenever am Installing Drivers for AMD be the basic old version or the one u asked in above post or even the latest one am getting the blue screen ..tried it 8 times different ways and everytime its the same so after logging in safe mode i went to device manager and uninstalled AMD RADEON 5650 whenever am doing this am not encountering bluescreen and its letting me login in normal mode ...after loggin in i follow ur instruction and used the software to remove everything related to AMD ..but as soon as i logging in am getting this ...am not connected to internet but somehow its finding the drivers for above 2 things and installing automatically

Also since i told that i got stuck in between while recovering when am booting in safe mode using the software i read this msg " RECOVERY PARTITION ,First NTFS BOOT SECTOR IS EITHER UNAVAILABLE or Corrupt

Any ideas ? After trying out so many things now i at least know how to get rid of bluescreen - that is just by removing radeon from device manager and not installing amd software
