My Vostro screen flickered twice,and showed a BSOD abruptly.It never went past a very distorted image of "Starting Windows" after that,showing a BSOD each time.I was able to boot it in Safe Mode though.I then disabled "AMD Radeon 6450M" using device manager.I booted it up normally again and it worked!Basically,its running on my Intel card now.However,if I try to switch my gpu to AMD,I get the BSOD.Re-enabling the AMD GPU and rebooting gives me a BSOD as well.After uninstalling my drivers,even re-installation resulted in a BSOD.Midway through the installation,it showed a BSOD and I had to switch to Safe Mode to disable my AMD Card again.Is this a hardware problem or a software problem?How can this be fixed?Any help would be greatly appreciated.
