I built a PC with Windows 7 Home 64-bit using the R9 270 (Gigabyte R9270C-GD). Upgraded to Windows 10, no problem (this has been about a year ago).
Had to reinstall Windows 10 from USB and now, after about 5 to 10 minutes of it working, the Windows disconnect tone sounds off and the monitor goes black. I've tried moving the card to another PCIe slot and several other things I've read at various forums with no success.
I've also put in a tech support ticket and have yet to hear back from AMD. What I'm really concerned about is reading a forum post at Tom's Hardware that said there was no fix for it at all. Several other posters advised to ditch the card and go with an nVidia card (which I would hate to do, since I've been using AMD cards since they were ATI, religiously.)
After several days of research and several attempts to fix the problem, I'm at the end of my rope and hope someone here can help me out.
Thank you in advance.
