Like my previous topic explains, I first started getting blue screen errors when using my computer on a normal day of use, and when watching a youtube video my computer screen blacked out and then causing a Blue Screen error "atikmdag.sys" Then I restarted my computer again and got the message “Display driver stopped responding and has recovered”, then a few minutes passed by and got the same blue screen error "atikmdag.sys". The problem got worse and then I started getting color lines (artifacts) all over my screen on every restart. I updated my drivers or my CCC(Catalyst Control Center) like they call it and the problem continued, but then I was getting a Blue Screen error "atikmpag.sys". I couldn't log into normal mode so it forced me to log into safe mode with networking. I then used Driver Sweeper to uninstall all the remainder drivers related to my AMD/ATI graphics card. I rebooted into normal mode and I was able to finally log in with no Blue Screen errors.
So now I've been using my computer with no drivers installed, so basically I guess my video card is disabled for now. But I still get color lines (artifacts) everytime I turn on my computer, and then those color lines disappear once windows starts. I'm able to watch youtube videos but I'm unable to watch HD videos because my video card has been disabled.
I'm asking the experts, does this mean that my video card is failing? or can it be something else causing "atikmpag.sys" when my drivers are installed? Is there a way to find out if its my video card or something else? I wouldn't like to spend money on a video card and later find out that wasn't the problem. I've had this computer for more than 2 years now and never had a problem until now. Any suggestions? Thanks in advance!
My PC info:
-Dell XPS Studio 435t
-Windows Vista 64
-My video card is a ATI Radeon HD 4850
-My power supply is 475 watts
-6gb of RAM
