so i just upgraded my graphics card form a nvidia gtx 650 ti boost to a msi r9 270x gaming
first i plugged in my card and uninstalled all nvidia drivers and software, and then i installed the newest beta amd drivers ( catalyst 14.1 ) , after playing battlefield 4 for 10 min i got a bsod
when i restarted my pc i tried playing the titanfall beta and again, after only 1 minut i got a bsod again...
my system specs are:
cooler master gx 450w
8gb corsair vengeance
wd black 1tb
msi R9 270x gaming 2gb
My guess is the power supply , please read the minimum requirement for that GPU , since I have the same GPU , if memory doesn't fail me , it requires at LEAST 500w , also I remember seeing other conditions as well . So please take a look at you graphic card box that it came with , also you can check the website .
I have the same problem as you. After upgrade from GTX460 to 270x I'am getting crashes.. My PSU has 400W (450W peak).. ..did you try another psu?
How did you solve this problem?
first of all: a 400 watt psu is wayyyy to less for a 270x, i could barely run my 270x with a 450w psu
and then i upgradet to a 650w and it fixed (almost) all the problems
second: try and remove all the drivers first with display driver uninstaller, and than instal the drivers back in
