I'm experiencing a driver issue I guess with my old & fair hp laptop. The thing is that when working in an application that is resource consuming, such as photoshop & playing a video in youtube chrome), for example I get a few second system freeze & a message that the "video driver hung and was restarted".
This was on the standard HP dual switchable video driver downloaded from hp: https://support.hp.com/us-en/drivers/selfservice/swdetails/hp-pavilion-dv7-6000-entertainment-notebook-pc-series/5046247/model/5076766/swItemId/ob-105178-1?sku=LR167EA
so I decided to follow the steps described on these forums for similar issues - uninstalled all the video drivers from intel, from amd (with the ati uninstall tool). updated the os with all the nessesary (& not so) updates, installed the latest intel driver (https://downloadcenter.intel.com/download/24971/Intel-HD-Graphics-Driver-for-Windows-7-8-64-bit?product=81500)
installed the catalyst driver 17.5.1 (http://support.amd.com/en-us/download/desktop/legacy?product=legacy3&os=Windows%207%20-%2064)
after it I restart my pc aaaand nothing - black screen. reboot again - see the windows welcome screen with freezed loading indicator. so the system doen't boot.
in safe mode see the logs - the ddkmdldr failed to load.
try to launch catalyst control center & see the message that the ati driver is either not installed or installed unproperly & then the catalyst shell tells me that there are no videocard parameters to set.
So I've uninstalled it again & decided to write here - wheather it is a software problem (then what driver version will give me stable work without issues) or hardware (maybe the ati videocard is dead? if so, how to diagnose it to be sure?)
upd: looks like windows starts with latest intel & ati 14 catalyst, but the welcome screen freezes for 2-3 of minutes. what is it?
