Hello, I just bought a Powercolor PCS+ 7970 and have encountered an issue where, usually, once I turn my computer on, I receive an error beep (supposedly memory) and the computer doesn't boot. If then I quickly turn the computer off and back on, the computer posts and boots normally. I already RMA'd one of these with a similar problem. I have tried two separate motherboards (ASUS M4A78LT-M and MSI 870-G45, both with newest bios versions) and the issue persists. I also reset the CMOS a couple times without fixing the problem. I have tested the card, the memory, and the PSU in another computer (similarly spec'd) with no problems. Also, a Sapphire 5870 2GB works without any issue in both motherboards. I am not sure if it is a compatibility issue or what. I am wholeheartedly confused and would like any help, thanks. Also, when it was booted, it performed spectacularly running both Furmark and Prime95 simultaneously without error and playing games rather well and benchmarking properly.
