A few months ago, I bought the Radeon HD 5670 512M GDDR5 graphics card. About three weeks ago, when my computer had overheated from gaming too much, I turned the fan speed of the video card up. After I had turned on my computer again hours later after turning it off to do some errands, I had noticed a brown screen with vertical stripes upon entering the desktop. This brown screened popped up maybe 3 seconds after the computer reached the desktop. The screen permanently stayed that way. Of course, my first instinct was to take out the video card, uninstall the driver and reinstall it again. Sometimes that would work, but when the computer would restart again, I still got the brown screen. I thought I had messed up the wiring of the circuit board of the video card. Since the card was still new, I requested an RMA from Sapphire to get a replacement. Today, I received a replacement card. Everything went swell when I had installed the video card. Again though, when I turned the computer off and turned it on after a few hours of not using it, I received the brown screen with vertical stripes. I don't understand why my computer is doing this, or the graphics card even. I did not change any of the settings on the replaced video card. All I did was install the most updated driver.
I reverted back to my old graphics card, the geforce 7900gtx when my Radeon HD 5670 was getting an RMA and I'm even using the geforce at the moment. Everything is working fine with the Nvidia geforce. No brown screen at the desktop.
I was hoping a few of you could help solve this issue. I really want to use my Radeon HD 5670. It's so much better than my 4 year old geforce 7900gtx. If this is any help I have Windows XP.
