I have an ATI Radeon HD 5770 (made by Sapphire). I'm currently trying to install Windows, however, my video card is overheating during installation and turning itself off.
I just switched mobos, but it happened on the previous one as well. (the old mobo had onboard video, though) Once windows is installed and the ATI drivers are installed the card stops overheating.
Any ideas on either how to fix the card or get it to work long enough to install windows? As of right now I get ~10 minutes, which is about 20% through expanding files.
