Hello,

I have problem with my 1 month old Radeon R9 270x. Since beginning while in-game it sometimes freezes computer and shows on screen strips in color depending on what before freeze was showing. Only solution was restarting computer. But that's not all, few days ago I could normally play Battlefield 3 without a single jam @ 50-80 fps on Ultra, now it lags every minute for a 1-2 seconds, which makes it unplayable, it's similar in Battlefield 4, but it doesn't occur in other games, Borderlands 2 for example. I have new Windows installation, tried newest drivers, and beta drivers and I have no idea what else I can do about it. One thing I know is i have 350 watt power supply, this card requires 500 watt minimum, but I can't check if it works on 500 watt.

Computer specs:
ASRock B85 Pro4
Intel i5-4440 @ 3.10GHz
Club 3d Radeon R9 270x
4GB RAM
HDDs: ST3750528AS 750 GB, SAMSUNG HD501LJ 500 GB (storing steam games mostly)
I'm not really sure about my power supply but I THINK it's this:
Antec Basiq BP350 350 Watt Power Supply

I can provide you a photo of strips when freezed if you need to just ask. I'm counting on your help didn't really find anything in Google.
